Before you apply read this first.: This is not a standard contract. We are not looking for someone to build something and disappear. We are looking for a developer who genuinely cares about people experiencing homelessness and wants to be part of something that actually changes lives. If that is not you, this post is not for you. If it is keep reading. What Is Operation Iron Gate: Operation Iron Gate is a physical intake hub in Vallejo, California built specifically for the unsheltered. Any homeless person can walk through our door and receive help no matter what barriers they are carrying, no matter what their documentation looks like, no matter how many times they have been turned away before. The rule is simple: nobody gets denied. We call it Yes by Default. Instead of looking for reasons to say no, we look for the next valid move. Every single time.When someone walks in, a case gets opened immediately. Every barrier they are facing gets documented. A next step gets started before they leave the building. And the system tracks every single movement of that case every action, every referral, every handoff until they actually receive the resource they need. Not a phone number on a piece of paper. The actual resource. It sounds too good to be true. That is exactly why we built the technology to make it real. What You Are Building — Phase 1 Only: We are currently hiring for Phase 1 only. This is the core platform build. We are keeping it focused. Once the pilot launches in Vallejo and the system is proven in the real world, we will move into the AI layer and long-term development. But right now we need Phase 1 built right. The platform is called DSAS the Digital Steward Authorization System. It is the brain of Operation Iron Gate. Here is what Phase 1 covers: * Case creation engine when someone walks through the door, a case opens immediately. One screen, one submit. * Barrier capture system every barrier the person is facing gets documented and connected to a next action. * Yes by Default enforcement a denial without a legal reason code is blocked by the system itself at the database level. * Three-tier triage system urgent cases get a 2-hour movement deadline with auto-calculated countdown. * Steward escalation queue hard cases route instantly to senior reviewers who make binding decisions. * MDO Live View: real-time monitoring screen showing every active case, who owns it, where it is stuck, how long it has been sitting. * Automated alert engine fires when a case stalls, when a deadline is missed, when a partner does not respond. * Glass Dashboard public-facing transparency layer showing the community how the system is performing in real time. * All data feeds automatically from the system. No manual entry ever. * IGAC credential system when someone arrives without ID, a credential is issued immediately on Day 1 so the case can keep moving. * 7-role permission matrix enforced at the API level on every endpoint. * Append-only audit trail tamper-evidence logging. Nothing gets deleted or edited after it is written.. The full technical specification is already built: * Every database field is named. * Every logic rule is written. * Every automated alert is defined. * Every role permission is mapped. You are not figuring out what to build. You are building something that is completely designed and ready to be coded. Technical Requirements Required: * Strong backend / full-stack development 3+ years building complex platforms * Relational database expertise PostgreSQL or MySQL complex logic enforced at the database level * Role-based access control enforced at the API level * Automated alert engines time-based and condition-based triggers * Append-only audit logging with tamper evidence * Real-time data feeds * REST API development Strongly preferred: React or similar framework for front-end interfaces. Mobile-responsive design Access Points may operate from tablets and phones. Civic tech, social services, healthcare, or government platform experience. We are open to your stack recommendation. Tell us what you would use and why. Who We Are Looking For: We need someone who is technically strong. But more than that we need someone who reads about Operation Iron Gate and feels something. Someone who understands that every field in this database is a real person's life. Someone who will flag a problem in the spec before building it wrong. Someone who stays when things get hard. Someone who wants to be part of this mission not just compensated for it. If you are only here for the money, this is not the right fit. If you want to build something that matters we want to talk to you. Compensation: Read This Carefully: This is a fixed-price contract via Upwork with milestone-based payments. Here is exactly how it works and why we structured it this way. We are paying in four milestones. Every single payment is tied to something real being delivered and confirmed not just promised. * 25% on project start you have skin in the game from day one and so do we. * 25% when the database and core logic is confirmed complete confirmed by the developer handoff checklist, not by your word alone. * 25% when the full intake flow and MDO Live View is confirmed complete again, confirmed by the checklist. * 25% at final sign-off when every single item on every Tier 1 handoff checklist is confirmed complete Nobody gets paid until something real is delivered and confirmed. The checklist is the protection for both of us. You cannot say something is done and collect payment if the checklist says otherwise. That is not a lack of trust that is how professional projects get built correctly. There is one more thing we need in this contract and we want to be upfront about it. The contract will include a scope change clause. That means if we ask you to build something that was not in the original specification something we did not think of, something new that becomes a change order and gets priced separately. It does not get quietly absorbed into the fixed price and it does not become a source of resentment on either side. You build what is specified. Anything beyond that gets negotiated openly and fairly. Fixed rate. Milestone payments. Handoff checklist as the payment trigger. Scope change clause in the contract. That is how we protect Pathfinders for Hope's mission funding and make sure you get treated fairly too. Additional terms: * NDA required before any specifications are shared * Work-for-Hire Agreement required before development begins all code belongs to Pathfinders for Hope * Rate is negotiable based on experience To Apply: Submit your proposal with your answers to all eight questions, a description of your most relevant project, your recommended stack, your honest Phase 1 timeline estimate, and your rate. We are building the operating system that proves homelessness can be solved one city at a time. If that is the kind of work you have been waiting for, we want to hear from you.

The tool runs 75 standardized queries across six AI platforms in parallel, captures structured responses and citations, and writes results to an Excel template for analysis. What you're building A Python application with three components: Six API adapters: OpenAI (ChatGPT), Anthropic (Claude), Perplexity, Google (Gemini), xAI (Grok), and SerpAPI (for Google AI Overviews). All hit the official APIs and return a normalized response object. Async orchestrator that fires all 75 queries in parallel across the six platforms, handles retries and rate limits, tags client domain and competitor mentions in real time, and writes results to a provided Excel template. Streamlit UI for click-to-run operation, with engagement metadata input, live progress monitoring, results preview, plus Google Drive upload and Slack notification integrations on completion.

Upwork Job Description Title: AI Agent Coach — Teach Me to Set Up & Build Agents with Claw (Beginner-Friendly, 1-on-1) Overview I'm a business owner who is comfortable with software but not a developer. I want to learn how to set up and use an open-source AI agent platform ("Claw" / OpenClaw-style agent framework) to build my own AI agents. Most importantly, I'm looking for someone who is genuinely comfortable explaining things in plain, non-technical terms and can help me build a strong, lasting understanding — not just get something working. What I'm Looking For You'll act as my personal coach and guide. The #1 requirement is teaching ability: you can take technical concepts and explain them simply, check that I actually understand, and build my confidence step by step. The goal is for me to truly understand how everything works so I can set up the platform and build agents on my own afterward. Teaching is the priority — not doing it all for me. Scope of Work Walk me through installation and setup from scratch, explaining each prerequisite in plain language Explain core concepts in beginner-friendly terms: what an agent is, tools/actions, prompts, memory, and how the pieces fit together Help me connect API keys and any required accounts safely Build 1–2 simple agents together so I learn by doing Show me how to test, debug, and troubleshoot when something breaks Pause regularly to make sure I understand before moving on Provide a short written "cheat sheet" or recording of our sessions so I can refer back About Me Comfortable with platforms like Google Workspace and basic automation Not a programmer — please explain things without heavy jargon, or define terms as we go I learn best by doing, with clear step-by-step guidance, and I like to fully understand things Ideal Candidate (Most Important) Excellent at explaining technical topics in simple, non-technical language Patient, encouraging, and focused on helping me genuinely understand — not just finishing the task Proven experience setting up and building AI agents (please share examples or a portfolio) Hands-on experience with Perplexity (including Comet / Computer) and Claude workspace is strongly preferred Comfortable with live screen-share sessions and teaching in real time Available for follow-up questions between sessions Format & Logistics Live 1-on-1 sessions via screen share (Zoom/Google Meet) Estimated 3–5 sessions of 60–90 minutes each (open to your recommendation) Sessions recorded for my reference To Apply, Please Include A brief description of your experience teaching beginners and building AI agents
