# Tomasz Woznica
Architects large-scale distributed systems and tackles core banking mainframe migrations.

## About

Tomasz Woznica architects large-scale online systems. While his foundation is in .NET and C#, he treats languages strictly as tools to solve hard problems—often diving into Node.js, Python, or COBOL when the job demands it.

At mBank, he tackles complex infrastructure migrations. Recently, he helped move a core banking system from a legacy mainframe to a distributed platform. His work centers on building C# runtimes that match raw mainframe processing speeds, ensuring thousands of banking operations finish within strict daily windows.
