Hi, I’m Mike! 👋

Background

#

I’m a full-stack software engineer and technical leader with a decade of experience across diverse industries. Based in Silesia, Poland 🇵🇱, specializing in web technologies.
I thrive on complex problems that actually matter to users. My toolkit spans Go, Ruby, JavaScript/TypeScript, and whatever else gets the job done.
When not coding, I’m usually playing video games, reading any weird fiction book I can get my hands on, speedcubing, or experimenting in the kitchen with my beautiful fiancée.
