I build product platforms from ambiguous ideas to reliable, scalable customer experiences.

What I'm looking for

I'm looking to own meaningful product problems from early ambiguity through production, using rapid prototyping, strong architecture, and iterative feedback to build experiences that last.

At GoodHabitz, I lead frontend architecture for the transition from a monolithic frontend to independently deployed micro-frontends. I build shared systems engineers can rely on, including a design system and the frontend for an LTI 1.3 integration used by enterprise customers inside their LMS platforms.

I work best when the problem is still taking shape. I use rapid prototypes and iterative feedback to turn unclear requirements into real product decisions, including GoodHabitz’s Lessons learning experience, while improving activity reporting and reducing server load by about 60%.

Previously at LeanScale, I built e-commerce and food-ordering products across React, Next.js, Node.js, and TypeScript, while supporting technical leadership through planning, reviews, feedback, and proof-of-concepts. At Durmaplay, I was the sole engineer responsible for products end to end, from early ideas through multiple production iterations.

I enjoy designing systems that stay useful as products evolve, from backend-for-frontend APIs and design systems to testing pipelines and infrastructure. I also use spec-first workflows with Claude Code to explore options quickly, delegate implementation work, and focus my time on technical direction and review.
