Joaquin Perez
As a designer, I bridge UX and engineering—refined instincts paired with technical depth. Using AI-assisted development, I prototype fast and ship real products: LLM-powered chat interfaces, API integrations, SaaS features, and dev tooling. I push for owning the loop: decide, build, ship, observe, iterate. Fewer handoffs, faster signal. Product isn't a phase—it's the whole cycle.
