Sole designer of mrgnlend - the core lending experience that scaled to hundreds of millions in TVL

As the only designer, I designed mrgnlend's core borrowing, lending, portfolio, and risk-management experience before launch and through the protocol's early life. I left before the points program and the major growth phase; Solana then entered a major bull market in late 2023, and the product foundation I designed remained in place as the protocol scaled to hundreds of millions in TVL, eventually peaking above $800M. I ran user research and worked closely with engineers, and also branded Omni, an AI agent.
