About

👋 Senior full-stack engineer, 19 years in, over 100 jobs delivered here at a 100% Job Success Score. Give me a spec and I'll build it front to back, by hand. I write the code myself and I understand every line of it, so when something breaks at 2am I'm the one who can actually fix it instead of guessing at it. Most of what I ship keeps running long after the demo, because it was built to. I've been writing code since I was 13. Nineteen years later there isn't much I haven't had to build, debug or rescue. New stack, new API, new platform, I pick it up fast, because after this long the fundamentals don't change and the rest is just documentation. WHAT I WORK IN Most of my work is Node.js, TypeScript, React, Next.js and PHP, on Postgres, MySQL, MongoDB and Redis. REST and GraphQL APIs, WebSockets and real-time systems, AWS, Docker and CI/CD. I also cover the automation and integration side when a project calls for it: WordPress, Shopify, Zapier, n8n, Make and GoHighLevel. Python when the job needs it. I BUILD FROM SCRATCH, ALL THE WAY DOWN Custom WordPress themes and plugins, not page-builder assembly. Custom PHP portals with their own auth, dashboards and admin tooling. I've even built the page-builder engine itself: a multi-tenant white-label site builder with WYSIWYG editing, reusable blocks, templates and per-tenant branding that generates and serves live sites for multiple clients at once. If it can be coded, I can build it, and I'd rather build the right thing than bolt together five plugins and hope they hold. SYSTEMS I'VE BUILT IN PRODUCTION A commercial IP-reputation and fraud API doing sub-3ms responses at 99.9% uptime, with API-key auth, rate limiting, batch endpoints and live docs. A multi-provider ad platform on the Meta and Google Ads APIs with OAuth: campaigns, ad sets, analytics, billing and automated rules. A real-time AI sales assistant built as a Chrome extension, with server-side token minting, streaming responses and a compliance guardrail th
