A full-stack LMS shipped to production at fpyacademy.com. Every lesson includes a context-aware AI tutor (Llama 3.3 70B via Groq) that grounds its answers in the live lesson content — a lightweight RAG pattern, streamed token-by-token with the Vercel AI SDK. Plus a course builder, quiz engine, role-based access, and PDF-exportable learning plans. 100+ commits.
An end-to-end operations platform coordinating field reps across 3,000+ retail stores. Unifies three Airtable bases and Supabase (PostGIS) into one real-time map dashboard with a route optimizer (NN → 2-opt → 3-opt), Kalman-smoothed GPS check-ins, and in-app turn-by-turn navigation. Result: reps log visits 4× faster. Built at Collab Collective Studio.
A "Twitter for on-chain real estate" where investors post tokenized property deals and earn DeFi yield. Engineered for scale and security: Fan-Out-on-Write feeds (500-post materialized timelines), Sign-In with Ethereum with replay protection, HMAC-signed sessions, CSRF middleware, and CSP hardening — all covered by 29 Vitest tests.
An open-source SaaS that automates the entire content cycle: it monitors RSS feeds and Reddit every 6 hours, scores trending topics with AI (Gemini 1.5 Flash + Groq Llama 3.3), and drafts LinkedIn posts, blogs, and newsletters for human review. Per-draft AI transparency — tokens, cost, and prompt used — at roughly $0.001 per trend. End-to-end tested with Playwright.
