About Fernando
Software engineer with 10+ years building web and mobile products. My specialty: frontends in React, Next.js, React Native and TypeScript that scale well and don't fall apart at the first refactor.
At Ka.app I worked on digital payments and crypto: SEPA Instant transfers, EUR fiat integrations, KYC, instant conversions. A domain where bugs cost real money, which taught me to be careful about what I ship to production.
I've delivered in fintech, automotive, legal tech, security and catering, always in distributed teams. I have enough backend (Node, Postgres, Mongo, Docker) to talk on equal terms with any API team, which saves meetings.
Clients come back for three reasons: I deliver on time, I communicate without noise, and I flag when a technical decision is going to cost more down the line. If that fits what you're looking for, let's talk.
