About

Industrial engineering background. Applied AI on production systems.

Currently

Shipping RAG and LLM-evaluation systems in production
Finishing my M.Sc. in Data Science at HEC Montréal (2026)
Open to discussing applied AI roles, freelance work, and interesting collaborations

Applied AI Engineer based in Montréal. I build production-grade machine learning and generative AI systems in an enterprise context, focused on the work that has to run after the demo ends. My background sits at the intersection of industrial engineering and data science, picked up at Polytechnique Montréal and HEC Montréal.

What I do today

Currently working on RAG pipelines, automated LLM-as-a-Judge evaluation frameworks, and performance monitoring systems for multiclass ML models in production. Before this, two years of RPA automation work taught me how to design systems that run reliably without supervision.

Outside of work

I build AI side projects across a few categories: agentic systems (StaffBot, Brevio AI), trading models (an HEC Data Challenge entry that generated $5.3M in simulated net profit), and specialized tools (PharmaOCR, Splendor.ai).

I co-founded the Polytechnique Business Case Center during my undergrad. Turning ambiguous business problems into structured analyses is most of the actual job.

From IE to applied AI

Industrial engineering taught me to look at systems end to end: flows, bottlenecks, what creates value and what just creates motion. Applied AI is the same lens with sharper tools. When a model takes hours of grinding work off someone's plate, the win is human, not technical.
