Rémy Ranger

Design and architecture of microservices automating datacenter fabric and backbone network infrastructure. I lead the VPC program, distributing customer networks across multiple availability zones — a key building block for European data sovereignty and resilience. I coordinate three teams: delivery reviews, workload planning, progress tracking, architecture reviews, and hands-on feature development. I also lead the AI enablement effort, introducing a methodology to break down features, produce implementation plans, and use AI-assisted code generation and review.

Project Management :Agility Scrum, 3 teams, architecture & delivery reviews.

Technical Stack :Golang, Kubernetes, Temporal, Kafka, Postgresql, Opentelemetry.

Define technical specifications and implement updates in line with client needs. I played a key role in developing a critical part of the system in Golang, optimizing it to handle high traffic volumes while meeting strict latency constraints. Contributed to the implementation of Golang automated testing and code quality indicators to enhance system reliability and maintainability. Led initiatives to decentralize data exchange using data connectors that adhere to European standards. Actively participated in European research programs focused on data spaces.
