About

Senior full-stack engineer building with security in mind. Currently the sole developer across a multi-brand technology platform — independently scoping, building, and shipping high-impact projects for clients including Red Bull, Beavertown, and Peak Performance.

Certified in eWPT and eJPT alongside Harvard's CS50 Cybersecurity, with practical experience across the offensive security toolset. A developer perspective that goes beyond writing features to understanding how web applications actually get broken.

Comfortable owning the full product lifecycle — infrastructure, DevOps, API design, front-end delivery — moving across the stack and across shifting priorities without losing momentum. Background spans product engineering at scale, early-stage startup development, and commercial consulting.

Sets up the CI/CD, writes the API, ships the front end, audits the server, and keeps everything running — often all in the same week.
