My Story

How I've evolved as a developer over the years.

Learning to Make Things Exist
Middle School

Programming sparked my curiosity when I learned QBasic in middle school. But it truly got my attention when I realized it could do real things, not just print text on a screen. Most of my first projects were remakes of games I enjoyed playing when I was younger.

Developing for the World
High School

I began seeking validation. Whether it was in the form of user feedback from projects I'd shipped, prizes from things I'd built for competitions, or cold hard cash; I had subconsciously internalized the feedback-iteration loop as a developer.

Intersection of Disciplines
Late High School & Early College

As I learnt more about the world, my interests shifted. I began to view code as a facilitator for other fields, a tool to amplify ideas that exist outside the Computer Science sphere. This helped me explore fresh ideas that I previously would not have fully appreciated.

Product-Driven Mindset
Present

Over the years, I went from creating software purely for the sake of writing code to developing helpful products that solve real problems. Of course, I still enjoy the development journey and all the decisions that come with it, but my primary motivator is now the value my work brings to people.
