I'm a senior full-stack engineer with 25 years of web experience — 20 of those remote, well before it was a default. I've shipped hundreds of projects for clients including MIT, Harvard, AWS, Condé Nast, Foreign Affairs, GreenWave and Perfumerías Unidas (Peru's largest beauty retailer). PHP and Laravel have been constants in that stack since they were the modern choice; today I lean on Laravel 12 + Inertia + React 19, plus the queue/Reverb/broadcast story for anything real-time.
Recent work
- AgentPost (2025 — present, founding engineer, solo). MCP-first disposable email service for AI agents. Laravel 12 + Inertia + React 19, Postfix pipe-transport into queued jobs, real-time push via Reverb. Shipped solo end-to-end, including DevOps and a multi-agent Claude Code workflow.
- Higher-ed WordPress engagements (Harvard, MIT, and others — 2021 — 2024, agency-mediated). Senior PM and editorial WordPress lead. Content structure, ACF schemas, implementation guidelines, design liaison, multi-engagement PM across several clients.
- GreenWave (2018 — 2026, lead architect / PM). Two web platforms + a React Native mobile app for an ocean-farming NGO. React, Laravel, WordPress, AWS Cognito, and several third-party APIs unified into one product surface.
- Earlier. 11+ years as lead frontend at GoodFolk LLC on Condé Nast (WIRED, GQ, Vanity Fair), Foreign Affairs, MIT and Manhattan Institute platforms; an L5 stint at AWS OpsCenter Console; independent UX-and-conversion work in California, including a Y Combinator startup under NDA.
How I work
I take on a small number of engagements each year — usually one to three at a time — because senior craft and AI-augmented delivery only multiply if the project gets the attention it deserves. Solo most of the time; for larger engagements I bring in a small bench of long-term collaborators (designer, mobile specialist, backend partner). 3 — 12+ month engagements, retainer or milestone. Shorter diagnostic work considered.
