I build software that thinks, moves and ships — from a quadruped robot patrolling on ROS 2, to a production backgammon game, to an AI front desk for local businesses on Next.js. Currently looking for my next software engineering role.

01 — About

Engineer by training,
builder by habit.

I'm a Computer Science graduate from Queen's University, based in the Greater Toronto Area. I like working across the whole stack — from ROS 2 nodes running on a quadruped robot, to Next.js dashboards, to the Python scripts that quietly save a team hours every week.

At Gold Line I partnered with a senior developer to ship a full-featured backgammon game to production, then engineered an autonomous security robot: a Unitree quadruped that patrols the building on its own, simulated in NVIDIA Omniverse before it ever touched real concrete.

Outside of work I was an active member of QMIND (Queen's AI & ML club) and QGDC (Queen's Game Dev club), and I run a small studio building custom-coded websites and AI automations for local businesses.
