Full Stack Developer

Full-Stack Developer | Web3 Builder

Frontend developer turned generalist who thrives on solving complex problems. Started building design systems at scale, now crafting DeFi protocols at an early-stage startup.

I love untangling challenging technical problems and always think holistically about the entire product ecosystem. Rather than just coding features, I dig deep to find optimal solutions that balance user needs, technical constraints, and business goals.

Not afraid to wear multiple hats—from planning and design to backend, DevOps, and custom tooling. I believe great products come from understanding every layer of the stack and how they interconnect.

Recent work includes building multi-chain DEXs, memepad platforms, and lending protocols across the Ripple ecosystem. The more complex the challenge, the more excited I get to dive in and find elegant solutions.

Always learning, always shipping. Confidence comes from preparation, not ego.
