Who You Are

A builder: You go from problem to prototype to production, closing gaps and creating real experiences.

Craft-obsessed: You hold high standards for clean, performant, accessible UI—even when shipping quickly.

Intuition-driven: You make smart architecture decisions, evaluate tradeoffs, and move forward even with ambiguous requirements.

GenAI-minded: You approach UI design and development from the perspective of GenAI applications, understanding how to create interfaces that best enable and represent GenAI functionality.

Frontend-first with full-stack awareness: React is your primary tool, with strong Angular capabilities. You understand how frontend connects to backend services.

Outcome-focused: You build around the user’s real experience, with every component and interaction considered.
