about

Co-founder at Volo since July 2026. Previously a founding engineer at Parabol Labs, where I worked on Parabol, a stablecoin protocol backed by U.S. Treasury Bills and overnight repo markets. My projects also include Rosetta, a block-level yield router for the Hyperliquid, Base, and Ethereum ecosystems.

Specializing in end-to-end blockchain infrastructure development, from smart contract architecture to production-ready applications. My expertise spans comprehensive SDK development (@parabolfi/core and @parabolfi/server), scalable AWS DevOps infrastructure, rigorous smart contract development and testing frameworks, and modern frontend applications built with Next.js v15.

Technical proficiencies include advanced performance optimizations, intelligent caching strategies, state management with TanStack Query, server-side actions, RESTful and GraphQL API design, comprehensive logging and monitoring through Sentry and PostHog integrations, secure SIWE authentication systems using Privy, blockchain data indexing with The Graph and SQD indexers, DeFi protocol integrations including Morpho lending protocols, extensive vaults and markets knowledge, and seamless integrations with leading swap aggregators including LiFi, Enso, and Relay protocols.
