ElevenLabs Conversational AI Expert — Long, Multi-Node Voice Agents with Tool Calls Project type: Hourly Experience level: Expert Duration: Short-term engagement with potential for ongoing work About the project We're building voice agents on ElevenLabs Conversational AI (Agents Platform) that run long, complex calls of 20+ nodes in the workflow builder, with multiple tool/function calls along the way. The agent is embedded directly into our app (using the ElevenLabs SDK) rather than the ElevenLabs widget. The agents work, but we're fighting duplicate questions/answers. The agent re-asks questions it already asked, or repeats information it already gave, at different points in the call. We need someone who has actually built and shipped long-running ElevenLabs voice agents (not just simple single-prompt bots) to help us fix the structural setup so calls stay coherent end to end. That covers workflow/node architecture, state handling, prompt design, tool orchestration, and our client-side integration. What you'll do ● Audit our current agent: workflow node structure, system/node prompts, tool definitions, and conversation flow. ● Audit our client-side integration (the ElevenLabs SDK embedded in our app): session/connection handling, event handling, client tools, and how local app state stays in sync with the conversation. Reconnects, double-fired events, or repeated client-tool calls can also cause re-asks. ● Diagnose the root causes of the duplicate question/answer behavior. Possible culprits include context/state not being tracked across nodes, overlapping node responsibilities, prompt ambiguity, retrieval/knowledge-base issues, or client-side state/event problems. ● Redesign the node graph and transitions so each node has a clear, non-overlapping job and the conversation can't loop or re-ask. ● Improve state/variable management across nodes: dynamic variables, captured data, and how it's passed forward so the agent "remembers" within a call. ● Tighten tool/function calling: when tools fire, how results are handled, error/timeout handling, and avoiding redundant calls. ● Address context-window and long-call degradation, plus turn-taking behavior that causes drift. ● Recommend the right structural patterns for flows this long (single agent vs. multi-agent/agent transfer, sub-agents, branching). ● Document the fixes and the patterns so our team can maintain and extend the setup. You're a strong fit if you have ● Demonstrable hands-on experience with ElevenLabs Conversational AI / Agents Platform. Please reference specific agents or projects you've built. ● Experience with the workflow/node builder for branching, multi-step calls, not just a single system prompt. ● Experience embedding ElevenLabs in a custom app via the SDK (React/JS, WebRTC/WebSocket), not just the drop-in widget. ● Solid grasp of tool/function calling (client tools and server tools/webhooks), including error handling. ● Strong prompt engineering for voice, plus understanding of LLM context windows, state, and conversation memory. ● Experience debugging long conversations for looping and repetition, including intermittent, hard-to-reproduce cases. ● Bonus: knowledge base / RAG, dynamic variables, multi-agent transfer, post-call analysis, and the ElevenLabs API/SDK. To apply, please include 1. A short description of a long, multi-node ElevenLabs agent you built: how many nodes, what tools, and what it did. 2. How you'd approach diagnosing duplicate question/answer issues in a 20+ node flow (a quick paragraph, since we want to see how you think). 3. Your availability and rate. Applications that just say "I'm an AI expert" without specific ElevenLabs experience will be skipped. We're looking for someone who has lived in this platform.

Custom iPad Client Closeout, Feedback & Review Automation Platform Developer Project Overview We are a high-end residential design-build firm seeking a developer to create a custom iPad-based client closeout platform. The system will be used during final project walkthroughs to conduct a structured satisfaction survey, capture referrals and testimonials, generate personalized AI-powered review content, and guide homeowners through the Google Review submission process. Our goal is to create a seamless, professional experience that increases client engagement, captures valuable feedback, improves our online reputation, and strengthens long-term client relationships. This project will be used by our team in homeowners' residences during project closeout meetings and should be designed to be simple, intuitive, and completed in just a few minutes. Desired Workflow 1. Team member conducts an in-person closeout survey with the homeowner. 2. Responses are entered into the iPad application. 3. The system evaluates client satisfaction and identifies highly satisfied clients. 4. AI generates a personalized review draft based on the client's actual responses. 5. The client reviews and edits the review if desired. 6. The client enters or confirms their Google account information. 7. The system directs the client to our Google Review page and facilitates the review submission process. 8. Survey results, testimonials, referral opportunities, and review data are stored in a database and/or Google Sheets. Survey Questions The application should allow us to customize and modify survey questions over time. Initial questions may include: Overall Satisfaction * How satisfied are you with your overall experience? * Did the completed project meet or exceed your expectations? * Would you hire us again for future projects? Communication * Were we responsive to your questions and concerns? * Did you feel informed throughout the process? Design & Construction Experience * Were you satisfied with the design process? * Were you satisfied with the quality of workmanship? * Did our team effectively solve challenges that arose during the project? Referrals & Advocacy * Would you recommend us to friends or family? * Would you be willing to provide a referral? * Would you be willing to participate in a future case study or testimonial? Marketing Permissions * May we use photos of your project in our marketing materials? * May we use portions of your testimonial or review in our marketing materials? AI Review Generation Based on survey responses, the application should generate a natural, authentic review draft. Example: "Working with Marvista Design + Build was a wonderful experience. Their team was responsive, professional, and highly organized throughout the entire process. We especially appreciated their communication, attention to detail, and commitment to quality. The finished project exceeded our expectations, and we would gladly recommend them to anyone considering a remodeling project." The generated reviews should vary in language and structure so they feel authentic and personalized. Additional Features Testimonial Capture * Collect written testimonials * Optional voice-to-text testimonial entry * Store testimonials in a searchable database Referral Capture * Identify clients willing to refer others * Capture referral contact information * Track referral opportunities Net Promoter Score (NPS) * Include NPS scoring * Flag dissatisfied clients for internal follow-up * Prevent unhappy clients from being directed toward public review requests Reporting Dashboard * Review completion statistics * NPS tracking * Referral tracking * Testimonial tracking * Historical reporting Data Storage Preferred integrations include: * Google Sheets * Google Workspace * Airtable * Cloud database solutions We are open to recommendations.

Your recommended technical approach for this project. 5. Estimated timeline and budget range. 6. Any suggestions for improving the workflow described above. We are less concerned with a specific technology stack and more interested in finding the right development partner who can help us create an exceptional client experience.

I'm building a medical education app for nurse anesthesia students called Remy at remyanesthesia.com. Built in Lovable with Supabase and React. The app is working but has several bugs I need fixed. Bugs to fix: Questions always appear in same order — need randomization Answer choices always in same order — need shuffling Select all that apply only allows one selection Bottom navigation disappears during flip card sessions Flip card drug name too large on mobile I will add you as a collaborator on my Lovable project. Estimated 3-5 hours. Looking for someone with Lovable and Supabase experience.

We're building a data-driven platform in the beauty/cosmetics space. We've already collected a very large volume of scraped product and brand data, and it's messy - inconsistent formats, duplicates, missing fields, mixed languages, and unreliable values. Your job is to turn that raw data into something clean and reliable, and to build the web application on top of it. This is not a quick gig. We're looking for someone to stay with us for roughly a year and grow with the product. What you'll be doing Building and maintaining a Next.js (App Router) front end and back end Designing and managing our Supabase setup (Postgres schema, RLS policies, auth, storage, edge functions) Cleaning, normalizing, and deduplicating large beauty datasets (this is a major part of the role) Building data pipelines to process and validate incoming scraped data Writing transformation/normalization logic (units, brand names, categories, ingredients, pricing, etc.) Setting up data-quality checks and monitoring Iterating on features with us as the product evolves You should have Strong production experience with Next.js and Supabase (please point to specific projects) Solid SQL/Postgres skills - not just ORMs Real experience cleaning and normalizing large, messy datasets (Python/pandas or similar is a plus) Comfort working with scraped data and all the inconsistencies it brings Good written English and reliable communication Ability to work independently and own your part of the product Nice to have Experience in e-commerce, catalog, or product-data projects Familiarity with data pipelines / ETL tooling Some ML/NLP experience for entity matching or text cleanup Budget We expect this to run around $4,000–$5,000 USD per month depending on experience and hours. This is a long-term commitment, so stability and quality matter more to us than the lowest rate. To apply, please include: Similar past work - links or short descriptions of Next.js + Supabase projects, and at least one data-cleaning/normalization project you've done. Your time zone and your typical available hours - we need to know there's reasonable overlap. Your expected monthly budget within the range above (or your rate if hourly). Applications that don't address all three points will not be considered. A short note on how you'd approach cleaning messy beauty product data is a big plus. We read every proposal carefully and respond quickly to strong candidates. Looking forward to working with you.

We are seeking an experienced mobile app developer to create a fully functional MVP that combines social features with an AI chat component. The app should be clean, stable, scalable, and ready for early user adoption, not just a clickable demo. Specific details about the app’s concept and logic will be shared under NDA.

About Charles River Apparel Charles River Apparel is a wholesale apparel manufacturer specializing in outerwear, rainwear, corporate apparel, and activewear. We do not sell directly to consumers. Our primary customers are promotional products distributors, decorators, screen printers, embroiderers, and corporate apparel buyers. Many of our customers are repeat buyers who know our products well and visit our website to browse products, check inventory, review product details, download assets, and place orders. Our goal is to improve the visual presentation of our website (https://www.charlesriverapparel.com) while maintaining the functionality our customers rely on. Project Objective We are looking for a designer to help us visualize what a refreshed version of our website could look like. We are not looking for a complete website redesign, UX strategy engagement, or development project. The purpose of this engagement is to create a visual direction that our leadership team can evaluate before determining what changes should be implemented. Current Environment Our website is powered by the CMS included within our ERP platform. While we have flexibility to modify HTML, CSS, and JavaScript, and can work with our ERP vendor to create custom content blocks when needed, we are not looking to fundamentally rebuild the platform. For that reason, concepts should be grounded in realistic enhancements that could reasonably be implemented within an existing enterprise CMS environment. The challenge we are trying to solve is not technical implementation. The challenge is defining the vision. We want to answer a simple question: "If Charles River Apparel were to modernize the visual design of its website, what could it look like?" Deliverables Please provide: • 2-3 homepage concepts • Desktop designs are sufficient for this phase • Concepts should remain aligned with our existing brand identity while presenting a more modern and polished experience • Focus on visual design, hierarchy, navigation treatment, imagery, typography, merchandising, and overall user interface We are open to creative ideas but would like concepts that feel achievable within the constraints of an existing enterprise platform. What We Are Not Looking For • Website strategy documents • User research • UX audits • Information architecture redesign • Customer journey mapping • Functional specifications • Development work • Coding or implementation recommendations Examples of Things We Would Like You to Consider • More contemporary homepage presentation • Improved use of photography and lifestyle imagery • Modern navigation styling • Better visual merchandising of products and categories • Cleaner use of whitespace and typography • Stronger visual storytelling while maintaining a professional B2B experience What We Need From You Examples of similar eCommerce, B2B, wholesale, or apparel-related design work. Estimated cost to create 2-3 homepage concepts. Estimated turnaround time. Confirmation that you can review our current website and work within the practical constraints described above. We are looking for a designer who can quickly translate an existing brand and website into a compelling visual concept that leadership can evaluate and use to guide future implementation decisions.
