Software Engineer
who ships with quality .

I build enterprise platforms with Java full stack, automate delivery with CI/CD, and make sure it all works because I test it too.

About

The engineer,
behind the code.

Most engineers pick a lane: frontend, backend, or ops. I chose to understand the whole pipeline, because shipping a feature means nothing if the tests don't cover it, the deployment breaks, or the observability is missing.

Currently at Orange Cyberdefense, building Angular security portals and Java/Vert.x microservices serving enterprise cybersecurity clients across multiple countries, working within international Agile teams.

My background spans full-stack development (Java, Angular), DevOps (Docker, Kubernetes, CI/CD, GCP), and quality engineering (TDD, BDD, Playwright, SonarQube). Three disciplines I believe belong together, not in separate silos.
