Senior Full-Stack Engineer (TypeScript · React · Node.js) based in Mallorca, Spain. I build web products and run them in production end to end: code, tests, CI/CD, infrastructure, monitoring.
Portfolio and case studies: dtpf.es · LinkedIn
11 applications in production, 8 of them public, 88,000+ automated tests behind them. Each app deploys from the same pipeline that runs its tests, so a red test never deploys, and each app has its own staging.
