About PredictPix
PredictPix is a community forecasting platform built for the Pi Network. Users make predictions on real-world events using Pi — demonstrating collective intelligence and real network utility (not gambling or speculation).
Our MVP is nearly complete and already deployed on DigitalOcean. Both backend (FastAPI) and frontend (Next.js 15) are live and connected to Supabase. We’re looking for a strong full-stack finisher to polish, stabilize, and finalize the Pi Testnet launch version.
What’s Already Working
FastAPI backend (predictpix.service) Next.js 15 frontend (predictpix-ui.service) Supabase (Postgres) database synced and live Nginx + SSL + Cloudflare configured Branding, theming, and market creation complete Pi Browser validation key deployed
What’s Left to Do Milestone 1 — Integration & UI Finalization Wire remaining data calls for /account, /leaderboard, and /admin pages Add leaderboard endpoint (aggregate user accuracy, participation, and results) Fix modal + JSON fetch issues (Prediction Details, History, Recent Activity) Confirm REST ↔ Supabase data consistency Verify CORS, Nginx, and domain routing for Pi Browser access Match visuals to reference screenshots and confirm full mobile responsiveness
Deliverable: PredictPix runs cleanly in the Pi Browser, with all pages functional and accurate Supabase data.
Milestone 2 — Testnet Deployment Readiness Confirm smooth operation on the DigitalOcean droplet (backend + frontend + Nginx) Ensure HTTPS, SSL, and domain routing are stable Validate that all prediction submissions, admin resolutions, and leaderboard updates complete end-to-end Prepare README.md and setup docs for GitHub (so new contributors can run the app locally) Provide a short video walkthrough or checklist verifying launch readiness
Deliverable: Fully deployable PredictPix MVP, operational in Pi Browser on the Pi Testnet, with database and admin tools functioning as expected.
Bonus (Optional Milestone) — Verified Pi SDK Integration Implement Pi SDK login + payments flow for Pi Testnet (non-custodial) Connect front-end SDK actions to new backend verification routes (/api/pi/payments/init and /complete) Verify transactions using PI_SERVER_API_KEY and confirm test-Pi movement on the Pi Testnet Update database entries to mark predictions as “paid” upon successful transaction Provide a brief demo video showing an end-to-end transaction in Pi Browser Deliverable: Functional Pi SDK payment integration verified on Testnet (Pi moves between test wallets successfully). Bonus: $150 released upon verified completion.
Ideal Developer
Solid experience with FastAPI + Next.js (App Router) Strong Supabase / PostgreSQL query + RPC skills Skilled in debugging deployed apps (not just new builds) Knowledge of async Python, fetch handling, and JSON structure validation Familiar with Ubuntu 22, Nginx, and DigitalOcean server configs (Bonus) Prior exposure to Pi Network SDK or blockchain testnets
Functional /account, /leaderboard, and /admin pages Verified prediction submission and resolution flows Mobile-ready, responsive UI for Pi Browser Fully deployable PredictPix MVP on Testnet Clear documentation + walkthrough for QA Optional Bonus: Verified Pi SDK payment integration with test-Pi
Timeline
Approx. 7 days from project start for Milestones 1 & 2 (+2–3 days optional for Pi SDK bonus milestone)

Why You’ll Enjoy This Project
You’ll be the developer who ships one of the first real Pi Network utility apps — PredictPix — to full testnet usability. Our goals are defined and you’ll work directly with the founders (no middle layers) to finalize the launch.
