Rockstar🎓
Top SchoolValentin Marchaud is a seasoned CTPO and engineering leader based in Paris with 11 years of experience building and scaling production systems, product roadmaps, and cross-functional teams. He blends hands-on backend and DevOps expertise—Node.js, TypeScript, Kubernetes, Terraform, OpenTelemetry—with product strategy, mentoring a 6+ person org and guiding customer onboarding and data integrations. Valentin has a proven track record delivering reliability and observability at scale (multi-region deployments, Grafana, OpenTelemetry) and has contributed to notable open-source projects like PM2 and OpenTelemetry, creating core context-management packages and improving MongoDB/Express instrumentation. He pairs pragmatic architectural judgment with low-latency coding practices and operational hardening, and his background includes solo-building commercial products and migrating complex bare-metal infrastructures to containerized, multi-provider platforms. An alumnus of 42, he is as comfortable in pull requests fixing Windows process spawning as he is shaping long-term product vision.
