Zachary GuerreroI own features end to end.
For 10+ years, I have been fixing the same problem: teams that need one person to own the full cycle. Research, design, code, deploy, iterate - no handoffs, no translation loss.
I design in Figma, build in whatever stack the team uses, deploy on whatever infrastructure fits, and measure what moves. No design theater - just shipped features that move metrics.
End-to-end ownership. Full-stack delivery. Any stack, full cycle.
Design, code, infrastructure, deploy, monitor. I own every layer of the product lifecycle. From fintech platforms to ISP tools to membership systems, I build experiences that users trust and businesses count on.
Ship from First Sketch to Deployment
I design end-to-end product experiences from user research to high-fidelity prototypes, then build them in code. No handoff tax, no translation loss.
Ship with Confidence, Not Guesswork
I validate solutions through user interviews, usability testing, and competitive analysis before writing a line of production code.
Ship Faster Because the System Scales Itself
I build design systems that keep teams aligned and accelerate product development. Reusable components, documented patterns, scalable architecture.
Ship in the Tools Your Team Already Uses
React, Next.js, Vue, Python, PHP, WordPress - I work in whatever stack the team uses and adapt without ramp-up time.

What's in My Toolkit
Research & Testing
I validate before I build. Watch what users do, not what they say.
Design
Tools I Use
- •Figma (daily driver)
- •Pen & Paper (early ideation)
- •Whimsical (flows, maps)
- •FigJam (collaboration)
What I Do
- •Wireframing & prototyping
- •High-fidelity mockups
- •Design systems
- •Visual design & branding
My Approach: Sketch first, prototype to validate, then build systems that scale.
10+ Years Building for the Web
React, Next.js, TypeScript, Tailwind CSS. I don't just design it—I can build it.
