What I'm looking for

I'm looking for a full-time remote backend role where I can build reliable C#/.NET services, work with mature codebases and international English-speaking teams, and deliver secure, well-tested APIs and data-processing platforms.

At ENGIE Global Markets, I build C# and ASP.NET Core backend components for ProductControl, a deal reconciliation platform that reduces booking risk through automated controls. I design MongoDB schemas, optimize queries, and implement CQRS-based services that preserve clean read and write paths.

I've also delivered DigiDoc services for AI document automation and electronic invoicing, handling PDF extraction, JSON processing, validation, exception management, Azure architecture, and secure integrations with Okta. I implement REST API contracts with backward compatibility, data validation, and safeguards against incorrect mappings or silent corruption.

Across ENGIE, INRIA Saclay, and Open Bee, I've strengthened data integrity, automated testing, CI/CD, and observability. I use GitHub Copilot daily while rigorously reviewing, refactoring, and validating generated code against SOLID, Clean Architecture, and SonarQube quality gates.
