Tomi
Architects.Senior Frontend Engineer specialising in real-time trading interfaces, DeFi protocols, and complex financial UIs that handle live onchain data.
Six years of shipping real products.
I specialise in the hard parts of frontend — real-time trading interfaces, complex DeFi UIs, and onchain interactions that feel instant. As the sole frontend owner across multiple live protocol products, I've shipped everything from lending platforms and perpetuals trading interfaces to a public-facing TypeScript SDK. I've won hackathons and built things with real TVL and real users.
Kasu Finance
RWA lending platform bridging DeFi and TradFi — built the full lending interface, portfolio dashboard, and KYC-gated onboarding from the ground up.
Unlimited Leverage
Onchain perpetuals trading platform on Arbitrum — architected the real-time trading interface with TradingView charts and sub-second WebSocket price feeds.
Spool V2 SDK
Public TypeScript SDK for the Spool V2 protocol (now Yelay) — designed the full API surface to abstract smart contract and subgraph interactions, enabling internal and third-party developers to integrate without touching the contracts directly.
Spool
Permissionless DeFi yield middleware (now Yelay) — built the frontend for risk-managed smart vaults and DAO governance, supporting portfolios with millions in TVL.
ETH Seoul Hackathon 2022
Decentralized science platform for milestone-based research funding and on-chain IP ownership via ipNFTs — built the full frontend including IPFS/Filecoin integration and smart contract interactions. in 4 days
WAMM
Subscription tracking app with Gmail scanning to auto-detect recurring charges — built with Next.js, Google OAuth, and automated renewal reminders via email. Shipped end-to-end using AI-assisted development.
