Nico Kastunowicz

Front End Engineer

I build accessible, pixel-perfect digital experiences for the web and mobile.

I’m a developer passionate about creating pixel-perfect user interfaces that blend thoughtful design with robust engineering. I specialize in translating design systems and visual concepts into polished, high-quality web and mobile experiences, where detail, motion, and usability matter as much as clean, maintainable code.

After spending the past five years as a full-time developer, I’m currently transitioning into freelance work. I’m excited to collaborate with design-driven small businesses and startups, helping turn strong visual ideas into carefully crafted digital products.

Previously, I’ve developed software across a range of environments — from agency work delivering multiple smaller projects to being part of development team building a complex enterprise application. This experience allows me to adapt easily, whether refining fine visual details or scaling robust front-end systems.

Outside of work, I’m a climber and mountaineer, and I enjoy the occasional game of chess. Challenge me!
