What I'm looking for

I'm looking to build reliable backend, cloud integration, or distributed systems software, with opportunities to improve production systems through testing, debugging, observability, and collaborative engineering.

I've built production backend services and transaction-processing workflows at Alten, designing and maintaining RESTful APIs in C++ and Python. I also developed Angular and TypeScript interfaces that connected users to backend services and operational data.

At Middleway, I designed scalable Azure data integration workflows using Azure Functions, Logic Apps, Service Bus, Cosmos DB, Blob Storage, Key Vault, and Entra ID. I built flows to ingest, validate, transform, and route data between internal systems and external services, while improving observability with Application Insights.

My work includes SQL troubleshooting and reconciliation, CI/CD pipelines, Bicep-based infrastructure as code, unit and regression testing, and production issue diagnosis. I focus on reliable, maintainable software and practical incremental improvements.

Earlier, I developed C#/.NET industrial and factory automation applications, worked with SQL data, Xamarin mobile development, RabbitMQ, Mosquitto, MQTT, TCP/IP, and UDP.
