About

I build full-stack products end-to-end —
from backend systems to polished interfaces.

I'm Nicole — a full-stack engineer focused on turning messy product requirements into usable, reliable software. I work mostly in React, Next.js, React Native and Expo, with TypeScript, AWS, PostgreSQL and Express on the backend.

At Parfour, I build across the web, mobile, and cloud stack: internal admin tooling, the Next.js web app, real-time streaming experiences, digital scorecards, social features, and AWS-backed services for auth, storage, and processing.

Before moving into full-stack product engineering, I worked in QA across mobile and web apps. That background still shapes how I build: I care about edge cases, clear feedback, accessibility, and interfaces that hold up outside the happy path.
