Hi, I’m Pavel.

I’m a Senior Software Engineer with over 10 years of experience building backend systems, APIs, and distributed applications.

I created this blog to share my knowledge, document my findings, and organize ideas that I find valuable in my work.

You’ll find articles covering both fundamental software engineering concepts and more advanced topics. Some posts explain core principles that every developer should understand, while others explore technologies and ideas I’m currently researching.
