Tools & Practices

Full-stack e-commerce web application built with Flask, Peewee ORM, and SQLite for the INF349 Advanced Web Technologies course. Features a REST API, product catalog UI, tax engine, shipping calculator, and online payment integration. Includes CI/CD with GitHub Actions and comprehensive pytest test suite.

R Data Visualization

Personal portfolio web app built with Streamlit, featuring bilingual support (FR/EN), project showcase, CV download, and an AI-powered chatbot that generates tailored cover letters using OpenAI GPT.

Python Streamlit OpenAI API

Modern portfolio website rebuilt with Astro and Tailwind CSS, deployed on GitHub Pages. Uses TypeScript for configuration and features a clean, fast, static site architecture.

Implementation of postfix notation evaluation using stacks and data structures in C++.

C++ Data Structures

Implementation of a professor file management system using linked lists and data structures in C++.

C++ Data Structures

Interactive 3D visualization of Keycube study data, deployed as a static web application on GitHub Pages. Exposes two autonomous views — Preference (participant-by-participant preference data + aggregate) and Reachability (per-finger and combined heatmaps) — rendered directly on a 3D model of the device. CSV datasets are transformed into browser-usable data at build time via a Python script (build_local_site.py). Supports English and French page variants. No Node.js or external Python packages required.

Team project (Oscar Neveux · Wilson Fotsing · Guy Junior Calvet · Jean-Christophe Barriault) for the Data Mining course at UQAC.

Automated classification of cybersecurity incidents (TruePositive vs Non-TruePositive) using the Microsoft GUIDE dataset (~2.4 GB), designed to help SOC analysts prioritize alerts at scale. The pipeline handles stratified sampling, NaN imputation, cardinality reduction (MITRE ATT&CK techniques, top-N grouping), temporal feature engineering, and full preprocessing exports. Three models were trained and compared — Logistic Regression + PCA, KNN + PCA, and Random Forest — with the Random Forest selected for production thanks to its best recall (fewest missed incidents). A Streamlit interface enables CSV-based batch analysis, manual form input, and KPI / ROC / PR visualizations.
