YieldFi — core engineering team at a DeFi protocol founded by YC alumni. Scaled to ~$200M peak TVL, $5M+ yield paid out, 60,000+ wallets and 13+ chains across 40+ strategies. I worked directly with the founders on product definition, not just delivery, and owned the entire frontend surface plus three production backend services.
- GM Markets — permissionless, wallet-native trading for tokenised stocks, ETFs, commodities and FX across Arbitrum, Base and Ethereum. Real-time vault data, rewards tracking, on-chain yield dashboards,
<300msperceived latency. - YieldFi V2 & V3 — multi-vault investing with points accrual across Curator-listed vaults, and yield-bearing token investing with major assets.
- Curator Dashboard — private analytics and control panel for vault managers: share analytics, token performance insights, configuration for new vault deployments.
- Gateway, Vault & RWA services — Node.js backends with Redis caching, consuming Alpaca APIs to power live stock charts, real-time trading data and portfolio positions.
- yfi-components — multi-brand component library on CSS design tokens. Cut new-product launch time 50–60%, powering 4+ brand rollouts, 7 applications and 50+ reusable components.
- PerfDash — API benchmarking, Lighthouse Web Vitals, build analysis and interaction-latency testing across multi-region, multi-device and throttled CPU/network. Cut p95/p99 latency pre-deploy.
- Telegram Web App + marketing bot — notifications, broadcast messaging, error reporting, user engagement.
Before that — Bamboo Rose (2022–2025)
- Implemented micro-frontend architecture with Web Components and Shadow DOM, migrating React builds from CRA to Vite inside an NX workspace — a 3× improvement in developer experience and company-wide adoption for frontend projects.
- Architected Br-Components, a centralised UI library adopted across teams as the single source of truth for UI.
- Led end-to-end delivery of Image Source Management, collaborating with product to refine requirements, running code reviews, and integrating an MFE into a legacy Java app with a Drag & Drop UX.
- Owned the Rose Clipper Chrome Extension (Manifest v3) end-to-end — development, performance tuning, security hardening, Chrome Web Store deployment and ongoing maintenance.
- Implemented PKCE OAuth2 authentication, integrating with the platform's Common-Login (SSO) application.
