Summary
🤩
Rockstar🎓
Top SchoolSebastian Wilzbach is a Staff Software Engineer with 13 years of experience building production fintech systems in Rust and a deep passion for compilers, functional programming and open source. He has a strong track record contributing to the D ecosystem—working on the D compiler, package manager DUB, LDC and the vibe.d web framework—bringing maintenance, tooling and language-level improvements. His background spans language design and runtime work (Storyscript, BRYTER) as well as modernizing legacy platforms into event-driven microservices (Scala, Rust). Based in Cyprus, he pairs academic training from TUM and Helsinki with hands-on experience across backend, build systems and testing infrastructure. Notably, he often focuses on long-term code health—refactoring, removing deprecated features and improving build/test tooling—rather than one-off features. Colleagues rely on him for thoughtful, low-level solutions that scale from compilers to fintech services.
