Vytautas Preikšaitis

Senior Frontend Developer · 9+ years in web

I'm a self-taught software engineer who switched careers to pursue what felt like a calling. What started as curiosity turned into nearly a decade of building products that people actually use — from marketing analytics dashboards to real-time multilingual meeting platforms serving thousands of users.

I care most about building things that work well and are pleasant to maintain. I've led frontend teams, broken monoliths into micro-frontends, shipped WebRTC streaming features, and championed testing practices that let teams deploy with confidence. I'm at my best when I can combine technical depth with product thinking.

Right now I'm expanding into full-stack development, digging into AI tooling, and exploring creative coding with WebGL. I'm always looking for the next interesting problem to solve.
