About

I live by a simple loop: Build; Measure; Learn. For me, coding isn’t just about syntax; it’s about shipping products that actually work. By day, I’m crafting seamless mobile experiences (iOS & Flutter) at GoTo Group. I’ve spent over 3 years deep in the mobile ecosystem, obsessing over smooth UIs and scalable architectures. But I can't sit still. I’m also a builder who loves solving problems for others. I built Investorsync to crack the code on fundraising, aggregating a database of 100k+ investors for startups. 👉 My Playground: Mobile: Flutter, iOS, React Native (I care deeply about UI performance!) The Fun Stuff: Tinkering with ML (TensorFlow/PoseNet) and Backend (Node/Python). 👉 Current Status: Building at GoTo, writing code, and always learning. If you're a founder looking for investor connections, DM me—I’m happy to share my database to help you out.
