About
Senior Full Stack Engineer with 13+ years building products end to end across mobile, web, and backend. Lately a lot of that has been consumer fintech: fast shipping, real money involved, and not much room for sloppy releases.
I obsess over two things: the experience users get and the experience developers have building it. So I push for work that actually helps the business, not just demos, and I put time into tests, automation, and keeping the codebase something both the team and AI agents can still work with a year from now.
Used to startup chaos (vague specs, sharp turns, owning things end to end). I mentor when I can. Remote only. Bilingual in English and Spanish. Mostly TypeScript, React / React Native, Node.js, and GraphQL.

- Owned the React Native (Expo) app and worked across our NestJS backend. Shipped Credit Builder; it reached $45K+ MRR in about two months.
- Migrated Apollo/GraphQL to REST with TanStack Query and Zustand, and moved business logic into services and view models, which gave us improved code maintainability and reduced frontend complexity.
- Built a backend-driven UI system enabling dynamic control of features, components, and copy without app redeploys, accelerating iteration speed and reducing reliance on OTA releases.
- Designed and implemented an event-driven backend architecture that decoupled modules and allowed scalable reactions to payments and onboarding events.
- Established testing practices from scratch, adding unit and end-to-end coverage (including web onboarding) to increase reliability and reduce production risk.
- Automated mobile release pipelines (OTA updates and App Store deployments), enabling high-frequency releases and faster feature delivery cycles.
