Hire the Best Product Designers in Concord, CA

Principal Product Designer with 15+ years making complex products feel simple, trustworthy, and intuitive. I've led design teams at Chase, JPMorgan, Invesco, and shipped products for Ogilvy, TabaPay, FastWill, Anthony Pompliano, and many startups. My work covers AI products, fintech, payments, legal tech, blockchain, and web3, across institutions managing hundreds of billions in assets and startups shipping products. I design AI-powered products and vibe code as a core part of my workflow. Using Claude Code and Figma MCP, I run an iterative design-to-prototype-and-back process that cuts concept-to-prototype time by 50%, generates multiple design directions faster, and produces near-production specs that reduce design-to-engineering back-and-forth. My approach is behavioral design. Understanding how people actually think, decide, and act shapes every design decision I make. That understanding drove a 12% increase in Zelle adoption at Chase, a 75% conversion improvement at FastWill, a legal tech platform for estate planning, and a 45% adoption increase for Respond, a B2B SaaS platform for law enforcement operations. What working with me looks like: → 50+ clients across fintech, web3, and AI spanning SaaS, B2B, B2C, and dashboard products → Vibe coding and AI-assisted workflows that move from concept to near-production prototype fast → Effective leading design teams, partnering cross-functionally, or operating as a sole contributor → Systems thinking built to scale beyond the project If you're building in fintech, AI, or web3, let's talk.
