Full-stack dev (Next.js + AI) — Day-trading SaaS — Revenue share, no upfront pay

Short pitch

Build a subscription web app for day traders: gated proprietary indicators + an AI tool that analyzes uploaded chart screenshots and suggests Entry / Stop-Loss / Take-Profit. Looking for one experienced full-stack developer (or a 2-person team) willing to work on a revenue-share basis.

Compensation (read carefully)

• No upfront payment.
• Paid from monthly recurring revenue once the product launches 5% of MRR
• This is a real risk-sharing arrangement. If you need cash up front, this is not the right gig and I respect that.

Scope (MVP, ~6–8 weeks solo)

• Next.js 14 + TypeScript + Tailwind + shadcn/ui
• Auth (Supabase or Clerk), Postgres
• Stripe subscriptions (Free trial / Pro / Elite) + customer portal + webhooks
• Gated indicator catalog (Pine Script + downloadable files, license keys)
• Screenshot upload → Vision LLM (GPT-4o or Claude Sonnet) → structured JSON with Entry/SL/TP + confidence → annotated overlay
• Plan-based rate limits, history dashboard
• Marketing site + legal pages (ToS, Privacy, Risk Disclosure)
• Deploy to Vercel; private GitHub repo handed over

Out of scope (MVP)

Broker/order execution, mobile app, backtesting, social features.

You probably fit if

• 3+ years shipping production Next.js/TypeScript apps
• Have integrated Stripe subscriptions end-to-end before
• Have shipped at least one feature using a vision LLM with structured output
• Comfortable working autonomously against a written brief

How to apply
