SOFTWARE ENGINEER

About Me

Product-minded software engineer building reliable web experiences.

I specialize in frontend and full-stack product development with React, TypeScript, Next.js, SvelteKit, GraphQL, and modern web architecture. At Houzz, I have delivered marketplace search and browse improvements, CMS-driven campaign platforms, experimentation workflows, and 3D and AI-assisted product integrations.

I work across product, design, backend, platform, personalization, and data teams to turn ambiguous requirements into maintainable releases. My approach combines product thinking with production debugging, QA planning, feature flags, analytics, and release monitoring.
