What I'm looking for

I’m looking for a role where I can own production-grade .NET microservices—especially event-driven payment and migration work—while mentoring teammates. I thrive in environments that value CI/CD, reliability, and hands-on problem solving.

I’m a Senior .NET Developer with 6+ years building production ASP.NET Core services across banking, telecom, and SaaS. I specialize in microservices and event-driven backends, working with RabbitMQ, Azure Service Bus, and cloud workloads on Azure and AWS.

At Orange Systems, I maintain and enhance the EPayments application, lead payment-flow integrations, and drive a Java → .NET 8 migration (including monitoring and troubleshooting). I’ve also helped deliver customer-facing payment capabilities and supported ongoing development for BFF and backend services supporting orange.md/shop.

I’ve also operated end-to-end production systems as a founding engineer at Ken, designing core .NET 8 backends (REST API, Ocelot gateway, workers) for scraping, AI, enrichment, and event processing. I enjoy pairing hands-on engineering with mentorship—mentoring and tutoring C#/.NET topics while keeping a strong focus on CI/CD, reliability, and production support.
