Work Experience

  • Leading the client-side architecture for Angstrom, a MEV-aware DEX — designing how the trading interface connects with protocol data, backend services, indexing systems, and on-chain execution flows.
  • Building the Angstrom web app with Next.js 15: multi-chain EVM wallet flows, live protocol state updates, on-chain execution, and real-time trading feedback across a Uniswap v4 hooks-based trading product.
  • Implementing a Rust backend gateway that consolidates subgraph data, off-chain indexed state, and RPC reads into frontend-optimized APIs for high-performance trading flows and protocol analytics.
  • Building multi-chain subgraphs on Goldsky with a custom AssemblyScript npm package to decode Angstrom-specific encoded data during the indexing pipeline.
  • Working end-to-end across product and engineering — refining UX flows, reviewing interface decisions, and translating user feedback and Google Analytics insights into product improvements.
  • Applying AI-assisted development workflows with Claude Code, Codex, and Gemini to accelerate implementation, debugging, and product iteration.
  • Delivered a full DeFi ecosystem (Swaps, Lending, Perps, Governance) and BeraJS, a modular Web3 SDK for EVM-compatible hooks and actions.
  • Implemented scalable data layers using GraphQL subgraphs, Apollo Client, and Goldsky for real-time state management.
  • Integrated advanced analytics tools like Google Analytics and Hotjar to drive data-informed UI/UX optimizations.
  • Led team sprints in Jira and conducted design reviews in Figma, utilizing Next.js 14, Wagmi, Viem, and Tailwind CSS to build high-fidelity interfaces.
