Summary
🤩
Rockstar🎓
Top SchoolPiotr Justyna is a seasoned senior consulting software engineer with 12+ years of experience building and rescuing large-scale, high-throughput systems, currently based in Dublin and working at LexisNexis Risk Solutions. He excels at simplifying and optimizing unreliable architectures—redesigning legacy APIs, introducing containers, .NET Core, AWS ECS, CI/CD and observability to achieve predictable, low-latency production behavior. A pragmatic leader and “firefighter,” he pairs hands-on coding with coaching and team formation, regularly deleting cruft and driving maintainable, side-effect-free design. Nighttime explorations in Haskell and Erlang inform his focus on correctness and performance, while his public GitHub reflects a bias toward rapid POCs and practical open-source contributions.
