About me

Szymon

Senior full-stack engineer, 15+ years. Laravel, TypeScript and Astro — custom websites, online stores and web applications, with the same person on the architecture, the code and the design. Spoko is Polish for “cool, easy, no stress”: that’s where the name comes from, and roughly how working together should feel.

Background and approach

I've built everything from front-end interfaces for international e-commerce platforms to web applications and sites written from scratch. My core stack is Laravel on the back end and Astro, Vue and TypeScript on the front, and I own the whole system — architecture, implementation, deployment and support. Every project gets a solution shaped around it, on a current stack.


AI tools are part of how I work: code review, automated tests, content editing, architecture decisions. That isn’t corner-cutting. Automated checks catch problems before they reach production, which leaves me time for the parts that actually move your business.


The rest is detail work — collaborating with UX designers, implementing SEO, setting up monitoring. I keep dependencies current and adopt new technologies early, so your project launches on a stack that won’t be dated in a year.
