Hi 👋, my name is

Marek Honzal

I build scalable frontends

I focus on architecture, state, and the parts of frontend you don't see.

At Apify, I'm a Senior Engineer shaping the public web toward world-class.

A Bit About Me

I believe the web should be not only usable, but maintainable - for the teams who build it.

That’s why I focus on frontend architecture, state management, and developer experience - the parts of engineering that help codebases grow without growing painful.

I didn’t start my career in tech - I spent 7 years in sales and marketing before taking a hard turn into software development. That pivot led me through an intensive bootcamp and into building everything from greenfield MVPs to design systems and internal platforms used by global teams.

Today, I work as a Senior Engineer at Apify, based in Prague, Czechia, fully focused on hands-on engineering. Before that, I spent several years at Applifting, where I balanced engineering with supporting the leadership of a 20+ person frontend team - mentoring developers and shaping tooling and practices.

I created this site to share what I’ve learned - and what I’m still learning - about building better frontends, growing as a developer, and tinkering on side projects that challenge how we think about code.
