I am building Dewy, an early-stage construction technology platform focused on construction buyout and subcontractor quote intelligence. The first MVP is intentionally narrow: users should be able to upload subcontractor quote/proposal documents and receive structured outputs showing included scope, exclusions, assumptions, qualifications, cost structure, alternates, allowances, and potential risk flags. I have already developed the product concept, construction logic, early workflows, and prototype direction using Codex/AI tools. I am not looking for someone to invent the product from scratch. I need a senior AI product engineer who can review what I have, determine what is usable, define a clean MVP architecture, and help turn the current direction into a working private beta. Initial scope: * Review the current prototype/code/product materials. * Identify what should be reused vs. rebuilt. * Recommend the MVP architecture and tech stack. * Define the AI document-processing workflow. * Design the structure for file upload, extraction, editable results, and export. * Help create a realistic build roadmap, timeline, and budget. * Potentially continue into hands-on MVP development if there is a strong fit. Ideal experience: * Full-stack SaaS / MVP development * AI / LLM application development * OpenAI API or similar model integrations * Document extraction or document intelligence workflows * PDF/DOCX parsing and structured data extraction * React / Next.js * Python * APIs and backend workflows * Supabase/Postgres or similar database experience * Vercel or similar deployment experience * Ability to work with a non-technical founder and translate business goals into a practical build plan This is not a full enterprise platform build yet. The first MVP should stay focused on one core workflow: Subcontractor quote documents in → structured buyout intelligence out. Please respond with: 1. Relevant AI/document extraction projects you have built. 2. How you would approach the MVP architecture. 3. Whether you recommend starting with an audit/roadmap before build. 4. Your hourly rate and availability. 5. Whether you are interested in ongoing build involvement after the initial review.

Developer needed to launch a family organizer app (backend + accounts) Short version I’ve already built a working prototype of a family management app. It looks and behaves the way I want. What it can’t do yet is the “behind the scenes” part: save information in one shared place so every family member sees the same thing on their own phone, let each person log in, and send reminder notifications. I need a developer to build that part and get the app live so my family can actually use it on our phones. One thing that matters a lot to me, please read carefully: after you finish, I need to be able to keep changing and improving the app myself, working with an AI assistant — without having to hire or contact anyone again. So everything you build has to be handed over to me completely, written cleanly and simply, and explained well enough that an AI assistant can understand it and help me make future edits. No locked-down systems, no “only I can touch this” setups, no surprise dependencies. I own all of it. What the app is It’s a private organizer for my household (two parents, six kids). It has five sections: • Today — a daily summary for each person (their schedule, their tasks, family meal/afternoon plans). • Schedule — a weekly calendar: who’s driving which kid to which school, each parent’s work day and hours, kids’ activities, meal and afternoon plans. • Chores — daily and weekly tasks you can assign to specific people, and check off when done. • Lists — grocery and supply lists. • Tonight — an evening summary of chores that still aren’t finished. The look, layout, colors, and how everything behaves are already done. I’m not asking you to design anything. I’m asking you to make it real and shared. What I need you to build 1. One shared place to store our information (the part it’s missing most). Right now, anything I type only saves on the device I typed it on. My wife’s phone and the kids’ devices don’t see it. I need all our information kept in one shared online location so that when anyone makes a change, everyone else’s device updates too, within a few seconds. 2. A login for each family member. Simple and family-friendly: you open the app, tap your name from a list, and type a PIN. Once you’ve logged in on your own phone, it should keep you logged in so you don’t have to do it every time. Every person — both parents and all six kids — gets their own login. Parents can edit everything; kids mainly see their own stuff and check off their own chores. The app already has a built-in “who’s using this” concept; your login system just needs to drive it for real. 3. Notifications to people’s phones. • Every morning, each person gets a notification with their summary for the day. • Every evening at 8:00 PM, each person gets a reminder of any chores they haven’t finished that day. The app already knows exactly what each of those messages should say — I just need them actually delivered to phones on schedule. 4. Shared photo proof for kids’ chores. When a kid marks a chore done, the app already makes them take a photo as proof. Right now that photo is stuck on the kid’s device. I need those photos saved in our shared location so my wife and I can see them from our own phones. What “done” looks like • My family can install or open the app on our phones and each log in with our name and PIN. • A change one person makes shows up on everyone else’s device. • Morning summaries and 8:00 PM chore reminders arrive as phone notifications. • Kids’ chore photos are visible to the parents on their own devices. • It runs reliably without me needing to babysit it. Very important: I need to be able to maintain it myself afterward I work on this app with an AI assistant, and I plan to keep improving it that way for a long time. So I’m asking that you: • Hand over everything — all the code, all the accounts and passwords, all the settings — in my name, owned by me. Nothing stays under your account. • Write it cleanly and simply. Please don’t over-complicate it or add tools and layers that aren’t truly needed. The simpler and more standard it is, the easier it is for me and an AI assistant to understand and change later. • Comment and document it in plain terms: what each part does, where things live, and how to make common changes (like adding a person, changing a notification time, or adjusting a list). • Write a short “how it works” guide for a non-developer — how to find things, how to change them safely, and how to undo a mistake. • Avoid lock-in. Use widely used, well-known building blocks (the kind an AI assistant will already understand), not anything obscure or proprietary that only you would know how to maintain. • Do a handoff call or video walking me through it so I’m comfortable taking it from there. If anything about how it’s built would make it hard for me to edit later on my own, please tell me up front. To apply, please tell me • A short note, in plain English, on how you’d approach this — especially how you’ll keep it simple and easy for me to maintain myself afterward. • Whether you’d build it so it works on iPhones and Android (and whether that’s a website-style app or an installable app — explain the trade-offs simply). • A rough estimate of cost and timeline. • One or two examples of similar things you’ve built. A few notes • This is a private app for my family only — not something I’m selling. It doesn’t need to handle thousands of users, just the eight of us. • Privacy matters: it includes my kids’ photos and our daily whereabouts, so it needs to be kept private and secure. • I already have the full working front end (the part you see and tap). I’ll share it with the right person. You’re building the engine behind it and getting it onto our phones.

Add Tests, Security Audit for Credit Cards, Possible Refactor: Vibe-coded Social Graphify + Lovable: Do not use ai to write your proposal, or for any of your communication. I do not need AI or an AI detection tool to know. It's obscene. I can't trust Claude to make tests. It always slyly reverts when making a productive change to changing the tests to mock data. So I need a human to implement them. Full-stack web dev js, python, llm's. Additional background or interest in: Graph Theory, Graph Neural Nets, Graphical Probabilistic Models, Bayesian Neural Nets, Category Theory, Pre-Deep Learning Natural Language Processing (Cfg's, etc.), Semantic Web Tech (rdf/owl/xbrl), Library Sciences, Pre-LLM Machine Learning (+Stat/Econometrics/etc.), Federated Learning and Crypto is appreciated.

About Savvix AI: Savvix AI is an AI-powered SaaS spend visibility and audit platform built for founder-led agencies. We help $1M–$10M agencies find and eliminate the SaaS waste hiding in their stack - dormant tools, ghost seats, overbilling, and subscriptions tied to employees who left months ago. We’re post-pilot, coming off a strong cohort, and entering our first official go-to-market phase. The Opportunity: We’re looking for a scrappy, relationship-driven BDR to own the top of our funnel. This is a contract role with commission and an equity grant - meaning you’re not just booking meetings, you’re building something alongside us. If you’ve sold into founder-led businesses or professional services agencies and you know how to earn trust before you pitch, this role was written for you. This role has a defined path to full-time: upon hitting defined revenue milestones and a successful funding event, this contract position converts to a full-time Account Executive role with end-to-end pipeline ownership. What You’ll Do: Your primary job is to get qualified discovery calls on the founder’s calendar. That means: -Identifying and researching marketing, PR, creative, and professional services agencies in the $1M–$10M ARR range -Executing warm outreach through LinkedIn, email, phone - prioritizing network-sourced introductions over cold volume -Running multi-touch follow-up sequences (expect 6–8 touches per prospect across channels before a response) -Qualifying prospects against ICP before booking — agency size, SaaS stack complexity, and the presence of a founder, finance, or ops lead managing subscriptions manually -Documenting and passing off each booked meeting with a brief prospect summary What You’re Not Doing You’re not closing deals, running demos, or handling objections post-call. Your job ends when the meeting is confirmed and the handoff notes are written. Who You Are: -You’ve sold into or worked within founder-led SMBs or agency environments — you understand how these operators think and what earns their attention -You’re a natural relationship-builder, not a high-volume cold caller. Warm intros and community-driven outreach are your default, not your backup plan -You’re persistent without being pushy - you understand that silence isn’t a no and that varying your channel matters more than changing your message -You’re comfortable working independently in an early-stage environment where the playbook exists but is still evolving -You have strong written communication skills and can adapt Savvix’s founder-story framing to feel authentic, not scripted -Familiarity with the agency or professional services space is a strong plus Compensation: This is a commission-based contract role with an equity grant for early contributors. Commission is paid per qualified meeting booked that advances to a discovery call. Specific rates discussed in the interview process. Path to Full-Time: This contract role is designed to convert. Upon hitting defined revenue milestones and a successful funding event, you’ll move into a full-time Account Executive position with end-to-end pipeline ownership — discovery through close. The specifics are worked out in the contractor agreement, not in the job posting, because we’d rather set those numbers with the right person at the table. Why Now: We’re coming off Demo Day (June 9) and moving into active GTM. The pipeline framework is proven, the playbook is documented, and the founder is ready to hand off top-of-funnel so she can focus on closing and product. You’d be the first sales hire. That comes with real upside.

Project Overview We are building an AI-powered voice receptionist agent for a dental practice client. The agent will handle inbound calls 24/7 — booking, rescheduling, and canceling appointments, answering FAQs, and escalating complex situations to a human. The voice layer is built in Retell.ai and the orchestration/automation flows run in n8n, with integration into a dental practice management systems. This is a hands-on build role, not consulting. You will design, configure, and iterate the agent working directly with our founding team. What You'll Build: Conversational voice flows for new and returning patients (booking, rescheduling, cancellations, FAQs, insurance questions, urgent/emergency triage) Clean escalation paths to human staff when the agent can't handle the call n8n workflows connecting the voice agent to the practice management API for real-time schedule reads/writes HIPAA-conscious configurations and tool choices throughout the stack Performance tracking and iterative prompt/flow improvements based on real call feedback Seeking an Expert Who: You've built multiple production voice agents, ideally in healthcare or dental, and can own the full stack from architecture to delivery. You think critically about latency, barge-in behavior, edge cases, and HIPAA compliance — not just happy-path flows. Requirements: Deep expertise in Retell.ai — prompt tuning, latency optimization, interruption/barge-in handling, LLM selection, and cost modeling Advanced n8n automation — complex branching logic, dynamic data handling, external API integrations, and error recovery Experience with dental or healthcare organizations — you understand how practices operate, what front desks actually deal with, and how to translate that into agent logic HIPAA awareness — you know which tools and configurations are appropriate for PHI workflows Track record of full-cycle delivery: scoping → build → pilot → iteration Nice to have: Dentrix Ascend integration, NexHealth, prior AI receptionist or appointment-booking agent for a clinic/practice. 📋 To Apply, Please Answer Have you built a production voice agent with Retell.ai? If yes, briefly describe it. What's your approach to managing Retell.ai per-minute costs on an inbound call agent? Have you worked with dental or healthcare clients before? What was the workflow? Paste a relevant n8n workflow screenshot or describe your most complex flow.
