The Right Tool for the Job.

I don't chase the hype. My approach to engineering is grounded in pragmatism and impact. I believe in using established, reliable tools to solve actual business problems efficiently.

While my core expertise lies within the React and TypeScript ecosystem, I maintain a strong focus on web fundamentals—semantic HTML, robust CSS, and accessible design. I am constantly expanding my toolkit to build more holistic, end-to-end solutions.
