Tell about yourself, your interesting and significant tasks, something complex in your career, what you are proud of.

I have been developing in C# for several years, specializing in creating scalable and maintainable applications. One interesting project was developing a performance monitoring system for a large client, where I had to integrate multiple data sources and ensure high processing speed.

A challenging task was optimizing the performance of a multithreaded application, where data races and deadlocks occurred. I managed to identify bottlenecks and rewrite critical sections using appropriate synchronization primitives.

I am proud that my solutions helped improve the stability and performance of the product, as well as implement best practices of clean code and automated testing within the team.
