Product design engineer

I design and
build product
interfaces.

I connect product design and front-end engineering, from workflows and prototypes to accessible interfaces in production.

Current focus: design systems

Building the design system used by roughly 3,500 engineers and designers.

See how I designed and built interfaces for complex workflows, with clear ownership and outcomes.

IVFCRYO shipment detail interface design showing shipment status and readiness information

Client work · Fertility logistics

IVFCRYO

Getting five parties ready before a shipment moves.

A shared workflow for patients and staff shipping fertility specimens between clinics. I owned design and front end, and partnered with engineers on the backend.

Product work · Home child care

Logatot

Less paperwork. More time with the actual children.

A voice-controlled platform for recording meals, naps, and attendance during the day. I led front-end work on a three-developer team, from interaction design to reusable components.

From design
to production.

My work spans product workflows, interaction design, and front-end implementation. The case studies make my role and contributions explicit.

Design decisions you can follow

I map workflows, prototype interactions, and work through loading, error, and recovery states with designers and engineers. The case studies show the decisions I owned and why.

Front-end engineering that carries the design through

I build the interfaces as well as design them, including the state changes and accessible behavior that static mockups leave open. Logatot shows my work on voice input, repair flows, and shared UI.

Shared foundations for a consistent product

Reusable components and clear interaction patterns help complex interfaces hold together. My current design systems work and public component library show how I support that foundation.
