About Me

Passionate full-stack developer crafting exceptional digital experiences

With over 7 years of experience in full-stack web development, I specialize in building modern, accessible, and performant applications with React/TypeScript on the frontend and .NET/Node.js on the backend. My journey started with a curiosity about how websites work, and it has evolved into a passion for turning complex requirements into clear, intuitive user experiences that are reliable in production.

I care about writing clean, maintainable code, with good tests and clear architecture, and I enjoy working closely with product and design to ship features that actually solve real problems. I like staying up to date with modern tools and best practices and sharing what I learn through code reviews, pairing, and helping other developers grow.
