Experience

My journey in AI and autonomous systems

Founding Lead Applied Scientist

Prizmal
Oct 2025 – Present

Researching and building efficient AI systems, including large-language-model compression, pruning and sparsification, model routing, and prompt optimization. Developed methods aimed at preserving principal subspaces and model quality under aggressive compression, and built routing systems that direct requests to the most cost-effective capable model. Also use agentic coding tools to accelerate research iteration and engineering velocity.

Machine Learning Technical Lead – Calibration, Odometry & Localization

Torc Robotics
Jan 2025 – Oct 2025

Led calibration, odometry, and localization work for autonomous driving. Owned and evolved classical and learned visual-odometry architectures, advanced keypoint-based perception models, implemented stereo co-factor-graph visual odometry, defined the technical roadmap, and mentored engineers.

Staff Computer Vision / Deep Learning Engineer

Torc Robotics
2023 – 2024

Drove deployment of perception modules on target hardware in real time after the Algolux acquisition. Led research on weather-robust perception, helped define image inference product requirements, and contributed to the design and integration of core features across the self-driving software stack.

Senior Computer Vision / Deep Learning Researcher & Engineer

Algolux
2021 – 2023

Led R&D for multi-object 2D/3D tracking and stereo-based perception, improving tracking accuracy and enabling dense depth estimation. Architected and deployed real-time embedded detection models and TensorRT-accelerated networks as part of the production perception stack and inference engine.

Senior Computer Vision / Machine Learning Researcher

Alcatraz AI
2018 – 2021

Built multi-face tracking, tailgate detection, and spoof-detection systems for access control. Designed auto-annotation and data pipelines, optimized models for edge devices, and integrated computer vision algorithms into a highly optimized C++/CUDA production codebase.

Computer Vision / Machine Learning Researcher

Gameloft
2016 – 2018

Developed intelligent systems for robotic mobile-game testing, including detection pipelines, OCR, reinforcement learning prototypes, and automation frameworks. Worked across C++, Python, and Lua to integrate perception, control, and tooling into a unified testing platform.

Teaching Experience

Supervision and mentorship

Academic Intern Supervisor & Mentor

University of Toronto
2023 – 2025

Supervised and mentored an intern for the Winter 2023 term, and another for the Fall 2024 and Winter 2025 terms, supporting research skills, engineering practices, and project execution.

Computer Vision Intern Supervisor

Alcatraz AI
2019

Supervised two intern research projects focused on bad-light detection and head-pose estimation from minimal data inputs, guiding algorithm design and implementation.
