About

BSc in Computer Science from Ontario Tech University (2026), based in the Greater Toronto Area. My work spans backend and mobile development, CI/CD pipelines, IT support, and — most recently — business banking, so I tend to approach problems from both the code and the operational side: how a system fails, why, and how to explain it clearly to whoever hits it next. This profile collects the repositories worth looking at.

Featured Projects

The flagship project here. RSB is a Python research framework for probabilistic sports forecasting: vectorized Monte Carlo simulation, market/odds evaluation via a pluggable provider abstraction, and backtesting against historical results. Predictions are persisted to SQLite alongside model versioning and feature-schema validation, with a pytest suite running through GitHub Actions. Guardrails intentionally block low-confidence output — it's actively developed and explicitly not live-betting-ready.

Auto+ — Vehicle Marketplace (team project)

A Flutter mobile marketplace for browsing and listing vehicles, built with a small team. Covers Google Sign-In / Firebase Authentication, Cloud Firestore-backed listings and profiles, and Firebase Storage image uploads.

Hotel Management Systemteam repository

A Java/Hibernate application for customer, room, booking, and service workflows, hosted under a teammate's account. My contribution was the controller layer — BookingController, CustomerController, RoomController, and ProvidedServiceController — connecting requests to the service and persistence layers.

Banking Systemacademic team project

A console-based banking system built for a QA-focused course, split into a front end for transaction processing and a back end for master-account/batch processing. Correctness was driven by a Bash-scripted automated test suite comparing generated output against expected transaction records.
