Sébastien Rufiange

Engineering leader with 18+ years building and scaling distributed platforms. Currently leading engineering and cloud at a Montréal ad-tech company — 20B+ requests/month across Cloudflare, GCP and AWS.

Notable achievements: reduced cloud costs 50%, built DevOps practice from zero to full Terraform/CI/CD maturity with one-click deploys, led a monolith-to-microservices migration that cut release cycles 60%, and shipped a functional bidding exchange in a single weekend to close a fundraising round.

I help teams with what I do daily:

- Platform architecture — distributed systems, cloud, API design

- DevOps maturity — CI/CD, Terraform, canary deployments, cost optimization

- AI engineering advisory — agent workflows, MCP, Claude/OpenAI integration

- Engineering leadership coaching — team structuring, hiring, process

I enjoy mandates where I can dig in, solve a real problem, and leave the team stronger than I found it. Architecture reviews, hands-on audits, and workshops where people walk out with something concrete — that's my sweet spot.

Ph.D. Software Engineering (ÉTS). Bilingual FR/EN. 9 years in Europe, back in Montréal. Hands-on leader — I still code 250+ merge requests per year along with reviewing and leading R&D activities.
