About Me

Why I Build

I'm a final-year Computer Science undergraduate, specialising in Machine Learning.

Over the years, I’ve been involved in Hackathons Healthcare Ops Tech Consulting
Through it all, I’ve found that the most fulfilling work is the kind that helps people. Teaching others and building tools that make someone’s day easier is what resonates with me most.

That’s what drew me to Tech – the ability to scale impact. A single well-designed system can solve problems far beyond what one person could do alone.

With Machine Learning, there’s an added layer of intrigue: bio-mimicry. Systems that evolve and learn like we do. The idea of nurturing digital intelligence from scratch fascinates me.

I’ve worked in domains ranging from Medical Crisis Response and Telehealth, to GenAI R&D and Enterprise AI Systems Whatever the challenge, I show up with curiosity, ownership, and the drive to build tech that actually helps people.
