Pav Osmolski - Senior Web Developer, Software Engineer and Open Source Developer

Portfolio LinkedIn

Web by trade. Open source by habit. Occasionally lost in graphics APIs.


About me

I'm a UK-based senior developer focused on front-end engineering, full-stack web development and polished user experiences. My day-to-day stack centres on JavaScript, React, Vue, PHP, WordPress and the modern web.

Outside conventional web development, I build and maintain open-source software across developer tooling, audio software, graphics/rendering and game modding. I particularly enjoy taking complicated systems apart, understanding why they behave the way they do, then making them cleaner, faster and easier to use.

I tend to gravitate towards projects where engineering, UI/UX and a slightly unreasonable amount of curiosity overlap.

What I care about

  • Building interfaces that feel considered, fast and accessible
  • Clean component architecture and maintainable front-end systems
  • Useful automation rather than automation for its own sake
  • Improving mature projects without losing what made them good
  • Documentation, validation and release workflows that make software easier to trust
  • Open-source work that solves an actual problem
