gte.xyz is a DeFi trading platform on MegaETH: portfolio tracker, AMM, token launchpad, central limit order book (CLOB) and perpetuals in one app.

As the sole frontend engineer, I built all 5 surfaces from zero to a public testnet used by over 1 million users in under a year.

Wallet login and transactions run on Privy and Viem. Balances, PnL, positions and orders update in real time over WebSockets.

App Switcher lets Coinbase users move between products, like Help Center and Tracer, from a single menu.

I built it in React and TypeScript, with i18n and Amplitude analytics, and worked with each product team to integrate it.

An A/B test measured a 0.45% lift in cross-product engagement among retail web users.

Coinbase sign-in for around 200,000 daily users, with OAuth for Apple and Google and sign-in with an Ethereum wallet, such as Coinbase Wallet, MetaMask or WalletConnect.

I built the flows in React and TypeScript, accessible (WCAG) and cross-browser.

Rendering and caching work on these flows cut load time by 20%.

Unified Signup 2.0 is one account creation flow shared across Coinbase products.

I led it, adding sign-up with Apple and Google and A/B testing the new flows behind feature flags.

Sign-up conversion went up 35%.

IntelliAgent is a real estate operations platform for Fathom Realty agents in North Carolina: prospecting, fee tracking and deal management in one place.

I built it in React, TypeScript and GraphQL for about 3,000 users, and designed the internal design system it shares with 2 other platforms.

I also replaced a manual process with automatic invoice generation for every transaction.
