Building software, mostly with AI.

Bart Stefanski
BARTWAW · 2026

I'm Bart Stefanski — a software engineer working remotely from Poland. I've been writing code since I was 12 and professionally since 2019, mostly around React, Next.js, TypeScript, Node.js, and the web-performance work that makes real products feel good.

Today I lead one of the teams at ZEN.COM. Before that I spent four years at Blazity wearing several hats (tech lead, head of engineering, head of open source).

// Beyond software

I box, amateur in the gym, and a pretty obsessive fan outside of it. If there's a big fight on, I'm watching it. Also a Lego fan, there's always a set half-built on my shelf.

I'm also genuinely into AI, optimistic about where it's going and paying close attention.

// Dream job

Not actively looking, but always open to hearing about interesting opportunities. What I'm after:

  • Autonomy over my work and real decision-making power
  • Small teams that move fast
  • AI, drone software, edge computing, or anything that feels like a Palantir-type problem
  • The company can be big as long as the team isn't

What I'll pass on:

  • Software houses, body leasing, outsourcing
  • Corporate structures where every decision needs a document and a month of approvals
  • If I can't ship something this week because someone hasn't signed off on a Confluence page, it's not for me

If that sounds like your team, reach out.
