Summary
🤩
Rockstar🎓
Top SchoolJonatan Kasperczak is a cybersecurity-focused SOC Analyst and seasoned software engineer with a decade of experience blending incident response, systems administration, and backend development. Based in Warsaw, he moved from Nokia's WS CyberSec/sys-admin role into a SOC Analyst post at EMCA while concurrently advancing a Master's in Artificial Intelligence, demonstrating a strong bridge between operational security and AI research. An active open-source contributor in the Elixir and Erlang ecosystems, his work spans core projects like Erlang/OTP and Elixir itself as well as numerical/ML libraries (Nx, Axon, Bumblebee) where he implemented performance-sensitive tensor ops and PyTorch model loaders. He also improves developer tooling and UX, contributing Elixir support to Monaco Editor and enhancements to Livebook and ExDoc, showing full-stack instincts beyond pure security. Notably, his contributions touch low-level runtime refactors and high-level ML integrations—an unusual combination that helps him reason about both system robustness and model deployment.
