Consulting
I've shipped production DeFi infrastructure across Lens Protocol and Push by Aave Labs — from smart contracts to backend systems processing millions of events per hour. I take on technical advisory and hands-on engagements through Synchronicity Labs, the software engineering studio I founded.
