Philippus Baalman
Scala Developer at ZorgDomein
Netherlands
Summary
🤩
Rockstar🎓
Top SchoolPhilippus Baalman is a seasoned Scala developer and former ScrumMaster with 11+ years of experience building resilient, reactive systems using Scala, Akka/Pekko and modern CI/CD practices. He blends hands-on backend engineering—contributing to high-profile open-source projects like Akka, Scala (2 & 3), sbt and akka-http—with product-focused agility gained from leading teams and scrum adoption. At Wehkamp and now ZorgDomein he applied functional and reactive principles to real-world retail and enterprise systems, while earlier roles show deep web and migration experience from PHP to modern stacks. His open-source work ranges from compiler and library fixes to maintaining clients like elastic4s and automation for dependency updates, revealing attention to correctness, compatibility and developer experience. Curious and pragmatic, he rekindled a passion for functional programming via Coursera courses and carries that λ-first mentality into production-grade systems and tooling.
