Senior full-stack engineer, 15 years, shipping production systems end-to-end solo — 104 completed contracts at a 5.0 rating on Upwork since 2011, so the track record is third-party-verifiable. Sole engineer on a multi-tenant SaaS platform for 3 years (50+ admin modules, Shopify e-commerce, Stripe billing, real-time chat). Also ship AI products (Gemini-powered English tutor with native iOS app, autonomous Claude/GPT content pipelines) and trading systems (Go-based Polymarket bot, Solana copy-trading, full algo-trading platform with live exchange APIs). Deep Shopify/e-commerce + CRO specialty. Available immediately, full-time or contract-to-hire. Happy to start with a short paid trial task so you can judge the work, not the résumé.
