Summary
🤩
Rockstar🎓
Top SchoolGrzegorz Uriazs is a Principal Software Engineer and founder with a decade of experience building secure, blockchain and DeFi systems, and a strong background in Erlang/Elixir core development. He co-founded Hocus, a self-hosted Codespaces alternative that attracted 3k+ stars and Hacker News front-page attention, and led high-stakes engineering at Student Coin where he designed a hot wallet that processed millions on launch day. At æternity he contributed to core protocol work—state channels, consensus research, and an Erlang-to-Purescript transpiler—demonstrating deep distributed-systems expertise. Passionate about cybersecurity and hacking, he blends offensive security curiosity with production-grade DevSecOps and Kubernetes practices. Comfortable across research and hands-on delivery, he pairs academic rigor from selective programs (RSI, University of Warsaw) with a knack for shipping resilient crypto infrastructure.
