Iterations Per Feature

I'm a self-driven full-stack developer and creative director who builds production-grade web applications, interactive games, and AI-powered SaaS platforms — end to end, from architecture to deployment.

I own the entire stack: Next.js frontend, Supabase database, Railway backend services, Vercel deployments, Stripe billing, Python async workers, and third-party AI API integrations. No handoffs. No gaps.

I've built multi-service production infrastructure, payment systems, authentication flows, real-time leaderboards, background job queues, and AI content pipelines — all as a solo founder.

Currently open to full-stack or frontend roles where shipping quality product is the culture, not the exception.

Bot Infrastructure

Production Services · Python Async

Designed and maintain three concurrent Python async bot services running 24/7 on Railway — TempleBot (community automation), V5 Bot (playable game character + lore via Google Sheets CSV), and SRCerer (Sorce support notifications). Each runs an independent asyncio event loop with exponential backoff retry logic, Supabase PostgreSQL integration, and Stripe webhook handling. Architected as Railway Worker services — not cron jobs — for continuous uptime.
