About

Protocol-focused blockchain engineer specializing in DeFi integrations and developer education. I build production systems from smart contracts to full-stack applications, and translate complex protocols into content developers actually use.

Currently: Junior Blockchain Developer at DeFiConnectCredit - Learning production DeFi integration (Aave v3, Uniswap, Curve, GMX) under senior engineers. Contributing to architecture review and internal documentation.

Background: Uniswap Hook Incubator (UHI7) Graduate | School of Solana Student | Core Protocol Engineer at TruthBounty


Featured Projects

Privacy Chronicles — Privacy Education Through Storytelling

Content Creation Track Winner, Zypherpunk Hackathon | Zcash & Mina Foundations | Live Demo

5-episode comic series (70+ pages) explaining zero-knowledge proofs and shielded transactions through narrative. Built immersive 3D solar system experience where each planet represents an episode, plus accessibility-first voice narration.
