Senior software engineer
Hi, I'm Mariusz Redzimski
I’m a senior software engineer building reliable backend systems and web applications. My work spans .NET, distributed systems, and frontend architecture with React, Next.js, and Angular.
I care about what happens beyond the happy path: how systems handle failures, how teams investigate problems, and how easily the next developer can understand the code. Here, I share practical lessons on testing, performance, and building software that holds up in production.
