Summary
👤
Senior🎓
Top SchoolPrzemysław Szczepaniak is a Staff Software Engineer based in London with 13+ years building systems-level and large-scale web infrastructure at Google, grounded in a Computer Science degree from Wroclaw University of Technology. He is polyglot and practical—fluent in C/C++, Rust, Java, Go and Python—and has shipped work across distributed computing, reliability engineering, embedded systems, GPU drivers, Android platform internals and graphics. His contributions span deep system architecture (modifying Android core libraries and namespaces) to cryptography maintenance in widely used open-source projects like Conscrypt, showing a blend of low-level correctness and production-readiness. Colleagues rely on him for automating and scaling complex services, improving observability and making fragile platform components robust. He’s equally at home auditing native cipher definitions as he is reworking build systems and library loading behavior, reflecting a hands-on engineer who prefers solving hard problems over theatrical tech.
