Dominic Dufour

I'm a data engineer and data scientist with a hands-on technical leadership background at Énergir, one of Quebec's largest energy distributors. I work across the modern data stack — Databricks, Spark, dbt, Terraform, Azure — while building practical machine learning and AI solutions, from large-scale data pipelines to LLM-powered applications used daily by hundreds of field technicians.

I led the transformation of a legacy data ecosystem into a modern analytics and ML platform spanning 10+ data sources, 500+ tables, and serving 15 business units. I've designed and deployed MLOps architectures that automate the full model lifecycle, built forecasting models that standardized predictions and generated $1.5M in contractual savings, and developed a LangGraph-based agent that reduced contract validation time from 30 minutes to 2 minutes. I also built the backend of a RAG application used by 500+ technicians daily, combining vector search and LLM capabilities to answer business queries automatically.

I'm passionate about building robust, reusable data products that drive real decision-making. As a technical lead, I advise on AI/ML solution design while staying hands-on — shipping pipelines daily, mentoring teams, and pushing the boundaries of what data and AI can achieve, particularly in industries undergoing transformation.
