Communications & Fundraising Specialist (DevComm) — Freelance Contractor | Remote | $50–$70/hr | Starting ~5–10 hrs/week | CST availability preferred (9a–4p) I'm looking for a nonprofit fundraising communicator — someone who is comfortable with donor stewardship, grant writing, and advocacy communications, and who brings a deep, lived fluency in progressive movement work. If your background is primarily in social media content, general marketing, or brand work with no experience in the nonprofit or social justice world, this is likely not the right fit. —— WHAT THIS ROLE IS This is a contractor position supporting my consulting practice, which serves clients working in abortion access, information democracy, freedom of the press, and cybersecurity education. The communications I produce straddle two lanes simultaneously: high-stakes fundraising and sharp advocacy storytelling. The person I'm looking for thinks in terms of donor relationships, movement strategy, and good-looking visual deliverables. —— PRIMARY RESPONSIBILITIES — Short-form content drafting — newsletters, op-eds, talking points, and similar deliverables that require a distinctive activist voice and genuine command of hope-based, intersectional framing; urgent calls to action and relationship-centered stewardship that move people to organize and take action, not just inform them Platforms: MailChimp, WordPress, Canva, Google Docs — Grant writing — drafting and editing 6-to-7-figure grant applications, LOIs, and funder reports with precision, fluency in program language, and a strong narrative arc. This will be an area I own in the beginning of onboarding, then share with you as you get comfortable with each nonprofit and their mission. I'm not going to throw you into the deep end here. Platforms: Google Docs, Google Sheets, grantee portals (Fluxx, etc.) — 1:1 donor communications — highly personalized stewardship and cultivation writing for major donors and individual funders (not listserv blasts); this will also include documenting and tracking donor stewardship touch points — helping plan when to reach out to whom, how often, and with what relevant updates Platform: Gmail — Funder research — identifying and profiling prospective foundation and individual donors aligned with client missions; I have a funding brief template I need help filling out for each donor/funding opportunity; knowledge of the major progressive funding landscape is strongly preferred Platforms: Instrumentl, Google Alerts, Guidestar, fundraising listservs, 990s — Light admin support — file organization, tracking deadlines and deliverables; a few hours per week at most Platforms: Google Workspace, Google Calendar, Instrumentl —— WHO YOU ARE You have genuine, demonstrable experience in the nonprofit and progressive advocacy worlds. You're familiar with how the communications department often straddles the fundraising department, and you are comfortable oscillating between the two. You bring: — Fluency in the language of intersectionality, feminist movement work, and progressive advocacy — not as buzzwords, but as a framework you actually think and communicate in. You know who Kimberlé Crenshaw is. — Hope-based communication instincts — you know how to write toward a vision, not just against a threat. — Comfort in tech-adjacent fields — cybersecurity, information democracy, the threat of AI, and digital rights have a learning curve; you're not intimidated by it, and ideally you've written in or around these spaces. — Knowledge of the major progressive funding ecosystem — you recognize the names, the priorities, and the culture of the foundations and intermediaries doing the most in this space. — A history of authentic major donor relationships — you've done the relationship work, not just the writing work. (I'm not expecting you to come with donor contacts and their emails — I just want to know you're comfortable helping a nonprofit build those ties authentically.) —— ON AI I need applicants to be upfront about the use of AI and LLMs. The work of my clients is often highly confidential, and given the nature of the fields I specialize in, I am very intentional about preventing Big Tech and AI companies from harvesting sensitive data. If you regularly use AI as a drafting or editing tool and have refined that workflow to the point where the final product is indistinguishably yours — that's not a disqualifier. We can discuss comfortable boundaries around where and when to use it. However, we cannot have work that doesn't reflect your own ability at its core. Please do not submit AI-generated writing samples or application materials. We're evaluating your instinct, your ear for activist language, and your ability to write in service of a cause — we'll be able to tell. —— WHAT TO SUBMIT Your application and samples should prove four things: 1. You know how to write persuasively. 2. You're well-versed in progressive and intersectional activism. 3. You have a fundraising background, preferably in or adjacent to the areas my clients work in. 4. You can create professional, eye-catching visual materials. If you're curious what I mean by that last one, you can see some of my work here: www.whatwesay.org/samples/ Whatever supplemental materials help prove the above are welcome. I will say — I'm a sucker for a good cover letter. Files should be submitted as PDFs. If files are large, upload to a shared drive, provide the link, and ensure permissions are open to outside viewers. —— ABOUT ME Hi! My name is Bevyn Howard. I live in Austin, and I am desperately hoping to turn Texas blue. My background is in Rhetoric and Writing — and since I didn't want to become a lawyer, I decided to use my persuasive skills to advocate for social justice missions I care deeply about. These include fighting racism, sexism, authoritarianism, and systemic power imbalances. As an undergrad, I completed my thesis on "White Feminism" and the ways white women perpetuate racism within the feminist movement. I left my previous full-time position due in part to burnout, so mental health and a flexible, sustainable working relationship matter deeply to me. I'm a WNBA fan, a distance runner, a weightlifter, and a cat parent to two Siamese who will absolutely make an appearance on video calls. Sorry in advance. Anyone who works with me is expected to have opinions, push back when they have a different idea, appreciate dry humor, and know that I value them for who they are — not just what they produce.

Job title: Researcher — Automated Cataloging for Mixed Media Collections (Barcode + Location Tracking) Category: Market Research / Research & Analysis Type: Fixed-price · Budget: $2,000 · Duration: 6 weeks · Experience level: Intermediate Overview We’re looking for a curious, detail-oriented researcher to produce a structured, professional research report (~10 pages) on the best available tools and workflows for cataloging mixed physical media collections (vinyl, CDs, books, films, video games, etc.) using barcode scanning or other direct-entry technology. Key Research Question What is the best physical media cataloging software with barcode scanning (or other available technology) and location tracking for mixed media collections? Context Collectors of physical media require an efficient method to catalog items. Manual data entry is time-consuming and prone to error. Barcode scanning presents a solution, but the optimal workflow depends on the collection’s size, the technical requirements of the database, and the need to catalog items with or without standard Universal Product Codes (UPCs). Objective Identify and evaluate available methods, products, programs, and other resources for creating a comprehensive digital inventory of a physical media collection using barcode scanning or other available technology for direct entry into a database. A user should be able to quickly identify the location and location history (which user had it last and where) of the media by querying an application. Also, provide a cost analysis of each option and how it scales based on collection size. What You’ll Do Conduct independent research on the assigned topic. Gather, review, and summarize academic papers, industry reports, and expert commentary. Synthesize findings into a clear, well-organized report following our standard Research Report Template. The report should reflect independent thinking, strong synthesis, and clear communication — not just a data dump. Who You Are Strong writing and analytical skills. Comfortable reading academic papers, summarizing complex ideas, and identifying key themes. Curious, self-directed, and able to manage your own workflow and deadlines. Excellent written English and ability to cite sources clearly. (Bonus) Familiarity with AI tools like ChatGPT, Elicit, or Perplexity for research support. Requirements Complete one ~10-page report within 6 weeks. Follow our provided report structure and formatting. Provide full references for all sources used. Disclose and fact-check any AI-assisted work per template guidelines. Meet weekly for 30–60 minutes to provide project updates to Advisors.

I’m looking for an AI Engineer to help build an automated red-teaming product based on open-source models. This is a short-term, hands-on project for around 2 months, with an expected commitment of about 20 hours per week. The goal is to build a specialized red-teaming engine that can generate adversarial prompts across different risk domains, severity levels, and attack strategies — then automatically run those prompts against target AI models to identify bad cases, failure patterns, and safety gaps. 🔍 What you’ll work on Build red-teaming systems on top of open-source LLMs, including fine-tuning, prompt optimization, evaluation pipelines, and model orchestration. Design automated prompt generation workflows across risk domains such as self-harm, hate, violence, sexual safety, misinformation, fraud, cyber, and other high-risk areas. Generate prompts across different harm levels, from benign edge cases to policy-borderline and clearly unsafe scenarios, while maintaining structured taxonomies and evaluation criteria. Run automated tests against target models such as Gemma, Llama, Qwen, or other open-source / closed-source models to surface jailbreak patterns, over-refusal, under-refusal, and policy inconsistencies. Build feedback loops that turn model failures into stronger red-team prompts, improved eval sets, remediation recommendations, and continuous safety testing. 🧠 What I’m looking for Hands-on experience with open-source LLMs, fine-tuning, LoRA / QLoRA, RAG, model evaluation, and LLM inference pipelines. Familiarity with AI safety, red teaming, adversarial prompting, jailbreaks, safety evals, or trust & safety systems. Ability to build end-to-end systems, including data pipelines, model serving, eval harnesses, scoring, dashboards, and automation workflows. Bonus if you’ve worked on model safety, content moderation, policy evaluation, agentic testing, or automated eval infrastructure. ⏳ Project setup Duration: around 2 months Time commitment: about 20 hours per week Format: flexible / remote-friendly Stage: early-stage build, from 0 to 1 🚀 Why this is interesting This is not about manually writing red-team prompts one by one. The goal is to build a scalable system that can continuously generate, test, categorize, and learn from model failures — helping teams understand where AI models break, why they break, and how to improve them. If you enjoy working with open-source models, AI safety, red teaming, and fast 0-to-1 product building, I’d love to chat. Feel free to DM me if this sounds like you, or if you know someone who might be a good fit.

I'm an independent inventor (Massachusetts LLC, patent-pending) developing a portable sports-training device that uses a projected laser line and a global-shutter mono camera to measure the angle of a small metal striking surface at the moment of impact. Target accuracy is ±0.5° on the angular measurement, with measurement latency under 2 seconds, and direct-sunlight robustness as a key engineering risk. This is an end-to-end Phase-0 feasibility engagement. The working assumption is laser-line + global-shutter mono camera with bandpass filtering, but I want your read on whether that's the right approach for this accuracy and these conditions. I have a strong lean, not a closed decision, and I'd rather you push back early than build something the wrong way. Once we align on the approach, you'll spec the bench rig (camera model, laser modules, filters, optics, baseline geometry, target mounting); I'll source the parts from your BOM and either ship the components for you to assemble or assemble and ship a built rig, your preference, whichever fits your workflow best. From there you capture data under controlled and outdoor conditions, develop the detection and calibration pipeline, and deliver a working codebase plus a written accuracy/robustness report. Hardware is returned to me on completion (or retained for a follow-on engagement if we both want to continue). What you'll deliver: 0. Approach review + rig spec. A short written deliverable (2–4 pages) covering: (a) your read on the proposed sensing approach, affirm + refine, or argue for an alternative with reasoning and a specific recommendation; (b) a bench-rig BOM with specific parts (camera model, laser modules, bandpass filters, optics, mounting, target plate) sized for the working distance and accuracy spec; (c) laser-to-camera baseline geometry with your reasoning, and recommended calibration targets. I'll source the parts from your BOM. We'll decide together whether I ship components for you to assemble or assemble and ship a built rig, whichever you'd rather. 1. Rig assembly or acceptance + baseline capture. Receive shipped parts (or built rig), assemble or validate alignment as appropriate, confirm basic optical performance against the M0 spec, then capture a baseline dataset (~200 frames per configuration) under controlled indoor lighting. Photos of the as-built rig and a setup diagram included. 2. Detection pipeline. A Python/OpenCV module that extracts the projected laser line with sub-pixel accuracy from frames at 60–100 fps. Sub-pixel line fit (Steger, Gaussian, parabolic) or weighted centroid, your choice with a short justification. 3. Calibration framework. Documented procedure and accompanying script for mapping pixel displacement to angular displacement of the target plate, accounting for camera intrinsics, lens distortion, and laser-to-camera baseline geometry. Validation against ground-truth rig angles. 4. Robustness data capture + analysis. Re-capture under (a) bright indoor with mixed daylight and (b) direct outdoor sunlight, for both laser variants with and without matched bandpass filters. Quantified accuracy + jitter per condition. 4–8 page PDF report comparing visible-red + bandpass vs. near-IR + matched bandpass. 5. Stretch (optional milestone): First cut at deriving angle-at-impact from a short pre/post-impact image sequence, pseudocode or working prototype, whichever fits the time budget. Deliverable format: Well-commented Python module(s) in a Git repo I'll provide, a README that walks a junior engineer through running the pipeline end-to-end, the captured datasets (raw frames + ground-truth angles), and a PDF report. What I'm looking for: - Comfort giving an unambiguous engineering recommendation: "use this approach with these parts" or "don't and here's why, and here's what to do instead." Phase 0 succeeds or fails based on the judgment in Milestone 0 as much as the algorithm in later milestones. - 5+ years of practical computer vision work, with shipped projects involving line/edge detection, sub-pixel feature localization, or structured-light triangulation. - Comfort doing your own benchtop work; mounting, alignment, basic optics handling. - Strong Python + OpenCV; comfort with NumPy/SciPy for the line-fit and calibration math. - Camera calibration experience (OpenCV calibrateCamera, distortion coefficients, projective geometry). - A workspace where you can run an outdoor sunlight test safely and legally with a Class-2 visible-red laser and a Class-1 IR laser module. - Bonus: prior work with laser triangulation, structured-light scanning, or sports/motion-tracking applications. - Bonus: experience deploying CV pipelines to Raspberry Pi or ESP32-S3-class hardware (potential follow-on scope). Engagement: - Fixed-price (preferred): $5,000–$7,500 total, paid across 5 milestones (approach review + rig spec → baseline capture → detection pipeline → calibration → robustness report). - Hourly alternative: $70–$140/hr with a 75-hour cap, then re-scope. - Duration: 5–7 calendar weeks (approach-review phase happens up front; ~1 week round-trip shipping after rig build). - Weekly 30-min check-ins (US Eastern preferred; flexible). - Hardware: shipped to you fully insured at my cost. Returned (insured, my prepaid label) on completion, or retained for follow-on engagement. - Possible follow-on: porting the pipeline to Raspberry Pi / ESP32-S3, IR laser variant tuning, integration support for the next prototype phase. Before we start: Short NDA + IP assignment signed before I ship the kit, share the technical design doc, or grant repo access. Upwork's standard terms transfer IP on payment, but I want a standalone signed PIIA on file as well, routine, less than 1 hour of your time. To apply, please include: 1. 1–2 examples of prior CV work involving sub-pixel localization, line fitting, or laser/structured-light triangulation. Paragraph + GitHub or paper link. 2. Three or four sentences on your approach to extracting a sub-pixel laser line centroid from a single frame. 3. Confirm you have a workspace where you can run both indoor and outdoor (direct-sunlight) image captures with a small bench rig, and that you're comfortable assembling the shipped kit. 4. Whether you prefer fixed-price or hourly, and your proposed milestone breakdown. 5. Without committing to a final answer until you've seen the full spec, a quick take: do you think projected laser line + global-shutter mono camera is the right sensing approach for ±0.5° angular accuracy at 60–100 fps under direct sunlight, or would you steer me toward a different approach? Two or three sentences. Looking forward to talking with strong candidates. Jason
