Zachary Guerrero
Design Engineer / UX Engineer
Design Engineer and UX Engineer with 10+ years across enterprise SaaS, insurance, and membership platforms. I work where product design and implementation overlap: framing workflows, designing interactions, building interfaces, and staying involved through launch. At Member Splash, I have shipped payment capabilities, redesigned member check-in, and improved the developer environment while working with Customer Success, support, and engineering. I work in React, Vue, Next.js, Python, and PHP. I ship with an AI-orchestrated development workflow: an orchestrator directing specialized subagents, with human review gates at every stage.

- •Identified and remediated a sensitive-data exposure in an API response by rewriting the handler so the data was no longer returned.
