Passionate about building scalable backend systems and full-stack applications that make an impact.
About Me
I'm a fourth-year Computer Science student at the University of Toronto. I'm passionate about backend engineering and full-stack development, building software that scales and solves real problems.
Currently, I'm working as a Software Developer Intern at RBC on the U.S. Cash Management team, building Java Spring Boot microservices for high-volume corporate payment processing. Previously, I interned at Traveltical and Appy.yo. I'm always looking to gain more experience as a software engineer and take on new challenges.
My long-term goal is to move to the United States and work as a software engineer where I can make a real impact, building products that people actually use every day.

Experience
Software Developer Intern, U.S. Cash Management
Royal Bank of Canada
- Built and maintained Java Spring Boot microservices supporting high-volume U.S. corporate payment processing within RBC Global Payments.
- Reduced end-to-end payment preprocessing latency by ~40–60% by introducing API versioning (v2) and parallelized Camunda workflows.
- Improved service scalability and fault tolerance by aligning backend services with Azure deployment patterns and offloading non-critical workloads to Spot VM capacity.
- Increased service reliability by implementing comprehensive unit tests using JUnit and Mockito, achieving 80%+ code coverage in a regulated banking environment.
