Senior Full-Stack Engineer · AI-Native — React · TypeScript · Node.js · AWS Bogotá, Colombia · Remote on US time zones
I build web, cloud and mobile products end to end, from data model to production deploy. 7+ years shipping for US and LATAM companies.
I use AI as a pipeline, not as autocomplete: specs first, then generation with Claude and Cursor, then tests and review standards that keep the output production-grade.
- Introduced spec-driven AI workflows that cut feature cycle time by ~40% on a production rewrite of a consumer financing platform.
- Built the MVP that secured $1M in funding.
- Built a React component library adopted by 100+ engineers.
- Integrated Plaid and Stripe payment flows processing $10K+/day.
