About me

Hi, I’m Cornerstone, and I’ve always been the guy who can’t stand clunky websites. So, I decided to build better ones: fast, intuitive, and easy to use.

I've worked with startups and teams to build scalable, user-focused products using TypeScript, React, Next.js, and TailwindCSS. What I enjoy most about frontend engineering is how it blends logic with creativity — every project is a puzzle waiting to be solved with code that not only works well but looks great.

My love for the web started young, fueled by curiosity about how websites actually worked. That curiosity turned into a drive to build interfaces that feel natural to use. One of my proudest moments was developing a web app for a masters student that was later selected among the best in her class.

So, if you're looking for a frontend developer who builds clean, scalable, and user-friendly experiences — let's create something great together.
