Work Experience
Sep 2025 – Dec 2025
Software Developer — Python / Backend Co-op
National Research Council Canada (NRC)
- Designed and implemented a FastAPI backend with RESTful endpoints serving ML predictions and geospatial data for building energy analysis.
- Engineered an ML model achieving 80% accuracy using 8–10 features; exposed predictions via API routes with SHAP explanations.
- Integrated zero-shot vision models (95% accuracy) and RAG pipelines, orchestrating outputs for retrofit recommendations under federal security standards.

My Projects
OC Transpo Live — Real-Time Bus Tracking
Full-stack web app displaying real-time bus arrival predictions for Ottawa transit stops. FastAPI backend with Postgres caching, a live GTFS-RT data pipeline, and an ML model (Random Forest/XGBoost) to improve arrival accuracy during delays.
Cross-Listing Desktop App (onelisting.ca)
Desktop app for bulk cross-listing products across eBay, Facebook Marketplace, and Kijiji. Features AI-powered listing generation from images, real-time profit/fee calculation, thumbnail generation, and secure credential storage.
Insulin Pump Simulator
Interactive simulation of the Tandem t:slim X2 insulin pump using Qt and C++. Simulates CGM data visualisation, bolus delivery, personal profile management, and Control-IQ logic with a time-acceleration model.
Podify Podcast Network
A desktop app written in C++ to manage podcasts and episodes, supporting dynamic playlists, audio/video handling, and factory-based object creation. Manual memory management implemented for performance.
