Summary
👤
Senior🎓
Top SchoolJakub Kowalski is a freelance software developer with nine years of experience specializing in cryptocurrency mining infrastructure, blockchain-related work, and language-agnostic engineering practices. He has repeatedly adapted and extended CryptoNote and other mining pool codebases single-handedly, delivering features like SSE-based miner streaming, GeoLite2 geolocation, and high-performance C/C++ and Rust bindings for Cuckoo PoW verification. Comfortable across Node.js, Go, PostgreSQL, Angular, and cloud platforms (GCE, Azure, Docker), he combines backend systems design with practical DevOps and front-end polish. His work spans many PoW algorithms (Ethash, Cuckoo, KAWPOW, Autolykos v2, Blake3, BeamHashIII) and includes production optimizations such as unified TCP/TLS ports and fee reductions. Based in Greater Poland, he pairs pragmatic product delivery with a deep curiosity about cryptography and low-level performance engineering—his public Open Zcash Pool repo reflects an early phase, not his current code quality.
