I design and ship production web and mobile products end to end. Recent work includes a multi-tenant field-service SaaS (Django, PostgreSQL, Stripe billing, Docker on AWS), an embedded Shopify analytics app (OAuth, Admin GraphQL, app billing, privacy webhooks), an AI English-speaking iOS app (React/TypeScript, Capacitor, FastAPI, Azure Speech, StoreKit 2 subscriptions with server-side verification), and an AWS market-data platform with external monitoring, versioned backups and a verified restore drill. I focus on clear requirements, automated testing, security, and maintainable code.
