The War

The War. What a frightening title. Well, since 5 AM on the 24th of February this became a reality for all Ukrainians. I vividly remember how I was woken up and told that it started. Sounds of rockets exploding around the city woke up sleeping people in Kyiv. We started packing stuff up. No panic, just methodically preparing for the worst.

API Client with C# Source Generators

Ever since the c# source generators were announced, I was wondering what are real-world examples where one would reasonably use them. I am working on web applications, but I do not seek performance gains on a gigantic planet-level scale. This crosses out most performance use-cases for me. What I do write at work is web APIs, sometimes facing other services. That is the direction I want to explore.

Hello, blog!

I usually keep everything to myself or colleagues, but Scott Hanselman inspired me to start inviting other people to accompany me during my adventures. I read that My words are wasted, so I decided to try writing about things I discover, work with, and have something to say about.
