ENERGY AND UTILITIES
May 2025 - Today (1 year and 3 months)
Nanterre, France
Design and development of a software hub for managing electric charging stations (OCPP 1.6 / 2.0 / 2.1 protocol) for B2C, B2B, and B2G segments, for a fleet of 70,000 stations (60K B2B + 10k B2C) deployed on AWS.

- Developed real-time OCPP communication components between stations and the cloud platform, using event-driven architecture (RabbitMQ) and WebSockets.
- Designed and deployed serverless functions (AWS Lambda) for automating charge management processes, reducing the operational complexity of asynchronous tasks.
- Implemented comprehensive observability using ELK / Kibana, enabling real-time monitoring of the station fleet status and proactive incident detection.
- Validated platform load capacity through Gatling campaigns (stress tests and load testing) on critical OCPP flows.
