Hi, I'm Baptiste Massemin, a 42-year-old engineer based in France with a background in both cloud infrastructure and large-scale service development.

I spent 6 years at Shopify, working across infrastructure and backend services at scale. In early 2026, I decided to go freelance.

I help my clients with cloud infrastructure (migrations, Kubernetes, cost optimization) as well as building and designing reliable services: event-driven architectures, idempotency, resilience patterns, and observability.

Interested in working together? Book a time that works for you.
