Summary
👤
Senior🎓
Top SchoolGrzegorz Wierzchowski is a data scientist and developer with 10 years of experience, grounded in an applied mathematics degree from Uniwersytet Jagielloński. He blends systems-level programming (C++, Rust) with data-focused languages (Python, Julia) and strong SQL skills in PostgreSQL to tackle back-end and scientific problems. Passionate about open source, he favors building transparent, reproducible tools for medicine and bioinformatics rather than commercial marketing or surveillance domains. Comfortable working remotely full- or part-time, he prefers roles that combine algorithmic rigor with practical data engineering. An analytical thinker, he brings a researcher’s mindset to production systems and a clear stance on ethical software choices.
