Selected work — the systems I've led and shipped. Most of it lived in private repos, so these are the stories instead: the problem, my role, the stack, and how it landed. The open source is below, and the full timeline is on my CV.
Led a team to launch a personalized web app for a consumer health company — the experience branches by login state and by what users answered earlier, surfacing tailored suggestions as it goes. 11 markets, two months, shipped on time. One small launch-day hiccup, then smooth sailing.
Tech lead on a video-consultation health platform — a React / Next.js frontend on a NestJS + GraphQL backend, wired to Auth0, Daily.co and Stripe. I own delivery across the whole stack, and built an Integrated API that bridges legacy data into the new platform.
Directed delivery of EasyMD — the first health video-conferencing app in Central America, shipped as both web and mobile. Also delivered the Nicaragua Azul museum site and an immigration law-firm document app. Apollo Server Express + MongoDB backends, React / React Native frontends, Heroku CI/CD.
Led maintenance and security hardening of a large Node.js monolith — patching authorization, CSRF and XSS holes — then led the team that blueprinted its move to a NestJS microservices architecture. Also shipped design-first agency frontends and an internal ordering chatbot.
A TUI on top of Taskwarrior for task management and PR review. Built with OpenTUI + Solid on Bun and shipped through a Homebrew tap. The tool I open every morning.
An elegant NestJS-based product monitoring system, with its own Homebrew tap for the companion CLI.
A Claude Code status-line plugin that surfaces your usage right in the prompt — session and weekly limits, reset times, colored progress bars.
