Aaron Effendi

Full Stack Developer

A tech enthusiast who thrives on challenges and learning. I believe programming isn't just about writing code, it's about problem-solving and communicating ideas clearly. The question I always ask on every project:

“How do we make this simpler?”

01. about me

Who I Am

I'm a Full Stack Developer who genuinely enjoys the craft, from wiring up a trading protocol at the backend to making the frontend feel effortless for the person using it. Over the years I've worked across fintech, AI, Web3, and enterprise software, but the through-line has always been the same: find the simplest solution that actually works, and build it well. I'm drawn to hard problems, curious by nature, and I think the best code is the kind nobody has to think twice about.

I enjoy working at the intersection of complex backend systems and polished frontend experiences, whether that means integrating a trading protocol, wiring up an AI pipeline, or crafting a smooth UI that makes it all feel effortless.
