About Me

I am a third year double degree student studying Computer Science and Business Administration. I love designing and developing unique UI/UX experiences and discovering new use cases for technology, especially automation related. I work across many programming languages, but I particularly enjoy C++ for its efficiency and my understanding of the compiler and CPU execution of the language.

I also have a heart for teaching and sharing knowledge. I teach 12 piano students through the Royal Conservatory of Music (RCM) and am building RCM-aligned apps to give them tailored, take-home learning. I'm passionate about solving problems at the business-technology intersection.

Where I've Worked

Jan 2025 - May 2025

Software Developer Co-op

Brock Solutions

Upgraded the SmartSort BHS at SLC international Airport from v10.5 to v14.0, executing ∼ 60% of the backend database migration and configuration while enhancing system performance through automated deployments and custom SmartSort services for oversized baggage
Wrote/debugged SQL stored procedures for baggage tracking/reporting, fixed CBIS logic bugs (double-counting) to improve throughput metric accuracy
Executed FAT validation checks, verifying new configurations in the customer-facing web client meet requirements prior to deployment
Traced end-to-end data flows across SmartSort services (e.g. Configuration Publisher, engines SMH/SAM/CoCoS) to troubleshoot defects and enforce architectural consistency
Worked daily with software, HMI and controls engineers to integrate new field devices (e.g. throughput counters, ATRs, EDS, diverters) into SLC’s BHS expansion, routinely resolving mismatched device configurations uncovered during controls testing.
