Sole designer at a DeFi yield optimizer with $584M peak TVL and 12,000 monthly users. Owned design end to end: research, core dApp redesign, design system and the delivery process with engineering

• Shipped a cross-vault transfer feature 4 days after a token delisting, cutting the deposit flow from 9 steps to 6
• Set up user testing from zero: launched a field-testing program in the product’s 10,000-member Discord and validated the new search and filtering in 98 unmoderated sessions

• Established the design and delivery workflow across product, design and engineering

Beefy collects no user analytics by design, so design decisions were validated through usability testing.
