Full-stack web developer with 20 years building data-driven web apps, payment & billing systems, and end-to-end third-party integrations. I work fluently in JavaScript, HTML/CSS, and PostgreSQL, and I've shipped e-commerce and Stripe payment flows (Elements/Checkout + webhooks), automated billing, invoicing, and metered-billing platforms, and REST API / webhook integrations — including remote delivery for a US-based company with daily US-timezone collaboration. I'm comfortable across the modern JAMstack: Netlify hosting and serverless/edge functions, Google Calendar API sync, and AI/LLM integrations, and I've published mobile apps to the App Store and Google Play. I build reliably, document my work, and ramp quickly on new tooling such as Supabase/PostgreSQL (Auth, Row-Level Security, Edge Functions). Available to start immediately, with several hours of daily overlap with US Eastern Time.
