Alexandros Petrache

Software Engineer

I develop solutions that make a change.

Node.js, TypeScript, CI/CD, React.js and more!

About

I'm a software engineer based in Athens, Greece, specializing in building scalable web applications. My journey began in May 2022, and I've rapidly progressed from learning the basics to developing complex full-stack applications and leading development teams.

Currently, I lead the Web Development team at AgoraLabs, where we're building innovative healthcare data solutions with AI. I focus on CI/CD pipelines, Kubernetes infrastructure, performance optimization, and integrating AI/ML into production systems. I've achieved significant results including 20x faster build times and 100x+ performance improvements.

I'm highly organized, prefer structured approaches, and adapt quickly to new environments. When I'm not coding, you'll find me working out, hiking, or reading books.
