2.5 years shipping DeFi products at a $1M-funded startup. 5 production bridges. 3 hackathon wins. From Figma prototyping to smart contract integration — I own the full product lifecycle.
About Me
The Engineer Behind the Product
I'm the frontend engineer who built every user-facing product at a venture-backed blockchain startup — from cross-chain bridge UIs to DeFi vault platforms to a modular B2B neobank SDK. If users touched it, I designed and built it.
Over 2.5 years at Nexus Network → Raga Finance, I shipped 5 production Arbitrum Orbit bridges for client chains, architected a 3-tier integration SDK, and designed all UI/UX from scratch in Figma. The company raised $1M from Hashed Emergent, Mask Network, CoinIX, and BreakOrbit.
It started at ETH Online 2023. Our hackathon project won the Polygon bounty, secured pre-seed funding, and became the company. Since then, I've kept competing — winning Unite DeFi 2025 and building a Uniswap v4 hook at ETH Global HackMoney 2026. I specialize in TypeScript, Wagmi/Viem, and modular frontend architecture that scales.
