Full Stack AI developer · Toronto
I build AI applications at Intact’s Data Lab, from their interfaces to the services behind them.
2025 to Present
Intact Insurance · Data Lab
I spent a year leading frontend development for production AI applications. Since then, I’ve expanded my scope to include backend development and automated testing. I’m currently building an end-to-end test suite to improve confidence in production deployments.
2022 to 2023
IBM · Canada Software Lab
Built Python automation estimated to save internal account-management teams more than 500 hours of manual work per week.
Selected work
Professional experience
Led React and TypeScript development for a year, extending shared application code for additional teams.
Migrated a FastAPI/PostgreSQL backend from synchronous to asynchronous I/O across database access, downstream-service clients, and API endpoints.
Building an end-to-end test suite that provisions real AWS resources and invokes services directly. Also write Vitest and pytest tests, maintain GitLab CI/CD pipelines, and contribute to infrastructure through Terraform.
Undergraduate thesis · 2024
Built a pipeline to generate 15,000 Leela Chess Zero evaluations and compare nine compact models. The convolutional models fit the training data more closely but did not beat the linear baseline on held-out positions.
Engineering capstone · 2023
Worked on CT-image preprocessing and results analysis in a five-person capstone with Trillium Health Partners. Evaluation on 78,545 public test images showed strong overall detection alongside substantial weaknesses in individual hemorrhage subtypes.
