About

I'm a DevOps & Cloud Engineer with a full-stack background, having personally architected, deployed, and maintained systems serving 1M+ monthly users in remote-first, globally distributed environments.

I design infrastructure for repeatability — every project I ship can be torn down and redeployed with a single command using Terraform and Ansible. I operate with an ownership mindset: comfortable as the sole technical decision-maker or as a contributor within larger engineering teams.

My academic background in GIS, Mathematics, and Computer Science from the University of Toronto gives me an analytical edge, and I'm currently studying for the AWS Certified Solutions Architect — Associate certification.
