About

I'm Marios Konnaris, a frontend software engineer with a passion for building interfaces that are both technically sound and genuinely delightful to use.

I believe great frontend work lives at the intersection of engineering rigour and design sensibility — writing clean, maintainable code while obsessing over the details that make a product feel exceptional.

Whether I'm architecting a complex React application, fine-tuning CSS animations, or optimising for Core Web Vitals, I bring the same care and attention to every layer of the stack.
