Experience
VP of Machine Learning
3D Western | Western University
- Serving as VP of Data/ML, leading a team of developers in model benchmarking and reinforcement learning to optimize a classifier that flags inappropriate 3D models for print approval.
- Built data generation workflows for 3D model analysis by scraping assets and creating automated rendering scripts to produce labeled image datasets for AI training.
Software Developer
WEFirst (Robotics) | Western University
- Programmed the swerve module to translate Xbox controller inputs into smooth omnidirectional motion for a competitive robotics platform.
- Hands-on assembly and wiring of the swerve drivetrain, including CAN bus integration, motor controllers, and encoder calibration.
- Developed and tuned closed-loop control algorithms for precise wheel heading and drive velocity during autonomous and teleop modes.
Software Engineering Intern
TeraGo | Markham, ON
- Developed a fully automated system to manage Jira tickets based on email notifications by using a Local LLM (Ollama) for structured and secure data extraction, Python for logic, and Microsoft’s Graph API for email retrieval.
IT Intern
Microcomputer Consulting Inc. | Mississauga, ON
- Configured and deployed client computers for multiple companies, including Windows installation, user account setup, and application/configuration changes based on company requirements.
Software Developer
WEMars | Western University
- Developed wireless camera and video streaming solutions using ESP32-CAM for a Mars rover platform.
- Researched networking protocols for reliable communication with a central hub.
- Investigated computer vision techniques for detecting visual markers used in rover navigation and competition tasks.
ProjectsProjects I'm Proud Of
AgntOS
An agent-native operating system built on NixOS — the LLM is not a sidecar, it's the central nervous system of the machine. Mutates itself via propose → apply → nixos-rebuild.
Local AI Platform
Fully dockerized local-first AI platform with secure remote access, model routing, MCP tools, and course-specific knowledge bases for grounded study and development workflows.
Homelab
Self-hosted Debian homelab with Docker Compose orchestration, Tailscale mesh VPN, Caddy reverse proxy, and 15+ services including local AI stack, media server, DNS filtering, and automated download pipelines.
Whack-A-ML
Reinforcement learning agent training a robotic arm to strike targets in Unity using PPO and curriculum learning.
FLEXFIRE-X
A wrist-mounted projectile launcher controlled by EMG muscle signals for intuitive, body-driven activation.
Cyberdeck (WIP)
Custom handheld Linux cyberdeck built around a Raspberry Pi 3B with a terminal-first boot flow, modular hardware, and a custom 3D-printed case.
Glyph
Leader-key command overlay for Windows with discoverable actions, per-app bindings, and custom themes.
Gaming & Mental Health Analyzer
ML system that predicts mental wellbeing risks across sleep, productivity, social isolation, dysregulation, and emotional problems based on gaming habits.
