Introduction

Developer focused on building interactive, modern web experiences.

I specialize in the MERN stack with a strong foundation in Java and Python. Blending solid engineering principles with an eye for UI and animation, I create digital products that are not only performant but also memorable. Whether it is solving complex problems or contributing to open source, I am driven by a passion for community and constant learning. I also use an AI-augmented workflow for faster prototyping, refactoring, and documentation while keeping architecture and quality decisions human-reviewed.
