Message

At Novibet, I developed and maintained backend services with C# and .NET 8, including event-driven processing with Apache Kafka. I also developed statistical workflows with MongoDB and Redis and optimized database queries and memory usage.

I improved processing reliability at Novibet with Redis RedLock distributed locking, and strengthened observability through .NET telemetry, Grafana metrics, and Kibana log analysis.

At Air Liquide, I engineered and maintained internal ERP systems for logistics, inventory, finance, and gas-production operations. I also built APIs for external ERP and fiscal integrations.

At PagBem, I architected a logistics system integrated with a payment platform and built .NET Core APIs for a driver-facing mobile app. Earlier, I developed retail solutions at Linx and commercial and internal systems at Recognition CBAB.
