AI Design Engineer <-> Product Technologist
Joaquin Perez
I bridge UX and engineering — refined design instincts paired with real technical depth. I prototype in React and TypeScript, ship production interfaces, and use Claude Code as my default development workflow. Storytelling skills and editorial instinct from the entertainment industry shape how I structure experiences and make decisions about what stays and what gets cut. I push for owning the full loop: decide, build, ship, observe, iterate. Fewer handoffs, faster signal.
