Rockstar🎓
Top SchoolJakub Wieczorek is a software developer with 13 years of experience building high-performance back-end systems and data pipelines, now focused on Rust for reliable, production-grade software. He has engineered extreme-write storage architectures and real-time log ingestion at scale, previously optimizing a log analysis platform to handle billions of events per day. Comfortable across languages (Rust, Python, C++, Perl), he combines practical systems design with a scientific background—holding an MEng in Technical Physics—which informs a methodical approach to debugging and performance tuning. An active open-source contributor, he improved build, testing and UI snapshot infrastructure for the well-regarded cargo-geiger project that detects unsafe Rust usage in crates. Based in the Cracow area, Jakub is drawn to technically challenging projects and the mathematical elegance behind systems, blending theoretical curiosity with hands-on delivery.
