Web3 frontend engineer focused on wallet UX, onchain security, and reliable data-heavy interfaces.

I build practical applications with React, TypeScript, Next.js, and Ethereum tooling. I also contribute bug fixes and regression tests to established open-source projects.

Open to Web3 frontend and React / Next.js frontend opportunities.

A Web3 security toolkit for inspecting token approvals, calldata, and EIP-712 signatures.

• Analyzes ERC-20, ERC-721, and Permit2 approvals
• Supports wallet-based revocation with chain validation and transaction simulation
• Built with Next.js, React, TypeScript, wagmi, viem, RainbowKit, and TanStack Query
• Tested with Vitest and Playwright

Turns an onchain transaction into a short animated visual story using RPC data directly.

• Decodes transaction activity without requiring a wallet connection or indexing API
• Presents transfers and contract interactions through an animated timeline
• Built with Next.js, React, TypeScript, viem, TanStack Query, and Framer Motion
• Includes unit and browser-level tests

A privacy-first browser extension that reveals onchain identity when hovering over Ethereum addresses or ENS names.

• Resolves ENS identities and validates Ethereum addresses
• Detects contracts and EIP-7702 delegated accounts
• Uses multicall for efficient onchain metadata lookup
• Built with React, TypeScript, viem, WXT, and Shadow DOM isolation
