MarginFi

Founding Product Designer for the fastest growing borrow/lend in DeFi

As the only designer on a team of six, I designed mrgnlend — a decentralized lending platform — from scratch. The product grew from $0 to over $300M in assets, becoming one of the highest TVL protocols on Solana. I also branded Omni, an AI agent powering crypto, and handled all video promotion and marketing using Premiere and After Effects.
