01 / Profile

Curious about how things work. Committed to making them better.

My experience spans full-stack development, mobile applications, and AI training and evaluation. I enjoy connecting those perspectives: thinking about how software feels to use, how it works underneath, and how it can evolve over time.

Across independent projects and team environments, I value clear communication, thoughtful technical choices, and learning through building. I’m interested in work that gives me meaningful problems to solve and people to learn alongside.
