Hi, I'm

Pritz Belleza

Senior Front-End Engineer

I brought Storybook and Chromatic into production, co-led a 2026 design-system rebrand, and I'm growing into full-stack. I care deeply about component quality, visual regression testing, and tooling that makes teams move faster.

Experience

Where I've worked and what I've shipped.

Software Engineer, Front-End

Huckberry

Building React/Redux features for a high-traffic outdoor retail platform. The biggest thing I've shipped here: stood up Storybook from scratch (config, CI pipeline, full component library) and brought in Chromatic so no UI change lands without a screenshot review. Co-led a company-wide rebrand, wiring design tokens from Figma all the way through to component migration across checkout, nav, and core UI. Also contributed to the Rails backend and ran A/B tests that moved conversion metrics.

Software Engineer

Appen

Two and a half years at an Australian AI/data company. Architected the centralized data collection platform that became core infrastructure: a multi-format client/API model that drove tens of millions in AUD revenue. Also built a global telephony app handling ISDN/VoIP calls across multi-million-dollar projects, a time-tracking system with role-based access, and Python automation that cut a significant chunk of manual project-manager work.
