Senior🎓
Top SchoolYorick Terweijden is a founder and seasoned software engineer based in Berlin with 13+ years of hands-on experience building high-performance distributed systems, system software, and developer tooling. He specializes in Go, gRPC, SQLite, and automation with Ansible, and has repeatedly delivered high-throughput data pipelines (including a CSV→SQLite converter achieving ~1.23 GB/s) and scalable job distribution systems that replaced legacy components like Gearman. Yorick has driven infrastructure transformations—scaling fleets from tens to hundreds of servers, deploying CEPH, and participating in ISO 27001 certification—while mentoring and recruiting engineers who progressed into leadership roles. His open-source contributions span projects such as Newscoop and replication-manager, where he focused on backend robustness, proxy architecture, and CMS migration to modern frameworks. Curious and pragmatic, he combines deep low-level systems work with research-oriented prototyping (LLM schema exploration, PDF and XML streaming tools), making him effective at turning complex technical challenges into production-ready solutions.
