};About
Practical engineering, clean delivery, and just enough frontend drama.
I studied Software Development & Network Engineering at Sheridan College and have hands-on experience across enterprise microservices, cloud data workflows, and full-stack product delivery.
My strongest work sits where backend reliability meets product experience: designing APIs, shaping data models, improving test suites, debugging production issues, and turning technical requirements into interfaces people can actually use.
