Background

About

Antonio Ruiz Brocal

Antonio Ruiz Brocal

Full-stack developer · Berlin

I'm a full-stack developer based in Berlin with 3+ years of hands-on experience in HTML, CSS, JavaScript and modern frameworks — mainly React, TypeScript and Node.js.

My strongest work so far is Ambulancias GoRuiz: a production platform I designed and built for ambulance scheduling and operations. I focus on clear UX for everyday users, reliable authentication and code that a small team can maintain.

I'm especially interested in healthtech, B2B SaaS and operations software — areas where I understand the domain from the inside.

Languages: English · Spanish (native) · German (B1–B2)

Path so far

  • Now
    Emergency Medical Services (EMS) — Spain & Germany · current role
  • 3+ yrs
    Web development · courses, personal projects & GoRuiz in production
  • Before
    Hospitality & driving instruction · team leadership, client-facing work, operations

Previous careers shaped how I work under pressure and with non-technical teams — they complement my development experience; they don't replace it.

How I work

I ship with the same habits I use on GoRuiz: version control, CI on every change, and Docker where environments need to match production. For speed I use AI-assisted tooling on routine work — always reviewed before merge. Architecture, auth and business logic stay mine.
