About

Engineering precision, design sensibility

I turn ideas into functional, well-structured web and mobile products with React, React Native, TypeScript, Node.js and C# — from Figma design to production delivery.

Every detail supports growth: solid architecture, reliable data and interfaces that communicate clearly.

I don't just ship pages: I ship systems that evolve safely and create real value for users and businesses.

Front-end & mobile

Modern stacks chosen by product strategy, not by the trend of the moment.
