About me

Curiosity,
made practical.

I’m a junior developer drawn to the part of technology you can see, feel and use.

Front-end development is where logic becomes an experience. I enjoy using JavaScript to turn an idea into something clear, responsive and genuinely useful.

My interests stretch from UI/UX and API integrations to AI-assisted applications and creative technology. I’m still learning, always asking better questions and happiest when solving a practical problem with a team.

The useful details matter more than a wall of logos: the problem, the thinking, the build and what I learned.

Go a little deeper

There is always
more to discover.

I care about the details beneath the interface—the small decisions that make an experience feel natural.
