About me:

Hi, I'm Szymon Miks Software Engineer based in Lębork, Poland.

I'm interested in software engineering, craftsmanship, clean architecture, clean code, design patterns and pragmatism in software development.

Occasionally, I blog about topics related to software engineering.

I'm still learning and developing my soft and programming skills. I'm always looking for new opportunities and challenges to grow up my skills. I love Python and the whole environment and community around this language.
