Full-Stack Developer for AI Email App

Project Description I'm looking for a developer to build a production-ready web app called "InboxAsk" — a tool where users connect their real email account(s) and ask natural-language questions like "find all invoices from this month" or "extract all links from the thread with Carl," and get a clean, accurate answer back. This is a real product for real users — not a demo. It needs to: - Connect to actual Gmail and Outlook accounts via OAuth (not mock data) - Use a real LLM (OpenAI or Anthropic API) to interpret the natural-language request and generate the answer - Actually search/process the user's real inbox content to produce results - Support multiple connected accounts per user (Gmail and/or Outlook) - Be secure and reliable enough to hold other people's private email data I have a full functional and design spec written out already (shared once we connect) covering: - Onboarding flow with a real "connect email account" step supporting both Gmail OAuth and Outlook OAuth - A dashboard with a prompt input bar where users type requests - An LLM-powered query layer that interprets the request and pulls the right data from the connected inbox(es), via Gmail API and Microsoft Graph API - Three result display types: lists (e.g. invoices), links (with source email context, open/copy actions), and attachments (with preview/download actions, file-type icons) - A request history/tracking page (past requests, status, timestamps, re-run capability) - A settings page (manage connected accounts, disconnect, add additional accounts) ## Ideal tech stack (or similar) - React + Tailwind CSS - Supabase (Auth, database, storage) - Gmail API (OAuth 2.0) and Microsoft Graph API (OAuth 2.0) — both required - OpenAI or Anthropic API for query interpretation and response generation - Clean, responsive, mobile-friendly UI — modern SaaS aesthetic (think Linear/Notion), not a generic template look Please flag in your proposal if you have prior experience with Gmail API and/or Microsoft Graph OAuth verification — this is a strong plus. ## Deliverables 1. Fully functioning production web app (all pages/flows above) connected to real Gmail and Outlook accounts 2. Supabase project set up with schema, auth, and secure handling of OAuth tokens for both providers 3. LLM integration wired up and working end-to-end against real inbox data 4. Source code handed over via GitHub repo, with basic setup/deployment documentation 5. Guidance on what's needed for Google and Microsoft OAuth verification submissions ## Ideal candidate - Strong React + Supabase experience - Direct prior experience with Gmail API OAuth and/or Microsoft Graph API — please confirm this specifically in your application - Experience integrating LLM APIs (OpenAI/Anthropic) into product features, not just chatbots - Security-conscious with handling of user credentials/tokens and private data - Good eye for clean UI/UX — please include 1-2 portfolio examples of clean dashboard or SaaS UI work, plus any project involving a real email/OAuth API integration ## Timeline Open to discussing based on proposed scope and milestone structure. ## To apply Please include: 1. Whether you've built a Gmail API and/or Microsoft Graph integration before, and a link/description if so 2. Your realistic estimate of timeline for this full scope at $650 3. Links to 1-2 relevant past projects (SaaS dashboards, LLM-integrated products, or email API work) 4. Your availability to start
