About

I'm a Computer Science student at the University of Ottawa who genuinely enjoys solving hard problems; the kind where you're stuck for a while and then it just clicks. Outside of that, you'll probably find me playing or watching basketball and soccer, checking sports stats way more than I should, or losing track of time in Rocket League.

Languages
Go Python Java SQL C / Bash JavaScript / TypeScript
Backend & Systems
FastAPI React Node.js REST APIs AWS Linux / Unix Git JUnit
Databases

Projects

A few things I've built, learned, and broken... along the way.

Project 01
Go / Networking

Net-Pulse

A Go diagnostics engine that checks whether a host's services actually work: DNS, ports, TCP, verified TLS, and HTTP, through a bounded worker pool. Untrusted targets are re-checked at connect time to block DNS rebinding.

Project 02
Python / AWS Security

CloudSentry

A read-only AWS security scanner where 12 deterministic checks decide every finding and Bedrock AI only explains it. React dashboard, 100+ tests in CI, deployed on EC2 with zero open inbound ports.

Go / Systems

PC Sentinel

A Windows system monitor shipped as one Go binary with an embedded React dashboard. Transparent health scoring, alerts with hysteresis so they don't spam, and an optional AI assistant grounded in measured data.
