Designed the core experience for a Solana lending protocol that later scaled to hundreds of millions in TVL

As the only designer on a team of six, I designed the core experience for mrgnlend — a decentralized lending platform — from scratch. The product later scaled to hundreds of millions in TVL, becoming one of the highest-TVL lending protocols on Solana. I also branded Omni, an AI agent powering crypto, and handled all video promotion and marketing using Premiere and After Effects.
