About

About Me

I'm a full-stack software engineer with 2+ years building and maintaining production web, backend, and mobile applications, primarily in TypeScript and JavaScript.

I work across the stack — from Angular and Flutter front-ends to Node.js/Express backends with third-party API integrations — and I'm comfortable owning reliability and scale, including re-architecting a processing pipeline that cut a 2-day job to about 6 hours.

I'm also hands-on with AI developer tooling — LLMs, prompt engineering, and AI agents — and I hold a B.Sc. in Software Engineering from Braude College.
