JakubBugyi
Software QA Engineer who writes code &
Frontend Developer who breaks things
before your users do.

I bridge the gap between quality and craft.
I'm a Software QA Engineer and Frontend Developer with a passion for building things that work and look great doing it. My background spans both sides of the development process: writing clean, interactive UIs and making sure they're bulletproof through rigorous testing.
Based in Slovakia. When I'm not hunting bugs or building components, I'm probably exploring new frontend techniques or contributing to open source. I believe great software is a product of both creativity and discipline.
A toolkit built for both building and breaking, on purpose.

I don't just build interfaces.
I do both, and that's rare.
Most developers specialize in one lane. I operate across both, which means I catch issues earlier, communicate across teams better, and ship software that works beautifully from the inside out.
Let's connect and build
something great.
I'm currently open to new opportunities: full-time roles, freelance projects, or just a good conversation about tech. Drop me a message.
