Senior Product Engineer
React · TypeScript · Vue · React Native · Payments · AI
Product engineer with 15 years in web. React, Vue and React Native, with a focus on payments. I build with AI agents every day.
A few things I've built
Product · Self-hosted
A private family hub that runs on my own NAS and installs on my phone as an app: the home's papers, renewals, health and a shared calendar in one place. Full-text search over 10,000+ documents, passkey and Face ID security, and two-way Google Calendar sync. Nothing leaves the house.
Product · Live
Tells you what to watch tonight and where to stream it in Spain. It learns your taste and only suggests what's on the platforms you already have. Built and run on my own.
Open source · AI tooling
My open-source AI toolkit for coding: reusable agents, skills and a workflow that work across Claude Code, Cursor and Codex.
Work · AI tooling
An AI tool I built so anyone on the team could debug payment issues fast. It reads our tickets, logs and data, keeps a library of past cases, and I taught around 20 engineers to use it.
Work · Payments
Six years building checkout and payment methods — Apple Pay, Google Pay, BNPL, wallets — on web (Vue) and mobile (React Native), with Stripe, Autopay and dLocal. I shipped features from idea to production.
Also building: QuickTrip, a React Native trip planner with a Fastify + PostgreSQL API, and F1FanWiki, Formula 1 stats in React.
Product-minded · AI-native
I work spec-first with AI agents, and stay in charge of quality and the decisions. I like being close to product and design, and leaving things better than I found them.
