Profile

About

Vancouver, Canada

I'm studying Computer Science at the University of British Columbia, expected to graduate in 2027. In parallel, I'm building software in industry at Optum (UnitedHealth Group), where I work on enterprise-scale healthcare SaaS.

I'm strongest where backend systems, DevOps, and product reliability meet: building services, improving deployment pipelines, writing automation, and helping teams ship with more confidence.

Edge

Strengths

The useful pattern in my work is not just writing features. It is keeping systems deployable, observable, tested, and easy for teammates to reason about.

Cloud-native platforms

I build and maintain microservices that run in modern cloud environments, with attention to reliability, deployment flow, and operational clarity.

Automation and delivery

I like tightening the path from code to production through CI/CD, repeatable test suites, and tooling that keeps releases predictable.

Quality under real constraints

I work across the stack to diagnose bugs, test performance, assess security risks, and turn issues into practical improvements.
