about

Blockchain engineer and entrepreneur with over a year of hands-on experience running my own blockchain company. Currently architecting and developing Parabol, an innovative stablecoin protocol that natively embeds risk-free returns through U.S. Treasury Bills and overnight repo markets, alongside Rosetta, a block-level yield router for Hyperliquid's ecosystem.

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.
