What I'm looking for

I’m looking for a B2B role where I can keep shipping .NET/Azure backend services end to end—integrating AI into real workflows for multi-tenant products across EU, UK, or US time zones.

I build and run .NET and SQL systems that power multi-tenant SaaS products, including notifications and ticketing modules processing ~10,000 events/day at Nerdio’s Microsoft-cloud management platform.

Across NetMinds’ loyalty platform for 1.8M+ app users, I delivered cloud-native services with Durable Azure Functions, Cosmos DB, and Service Bus, and re-architected batch processing to improve throughput more than 5x.

Earlier at EPAM and Capgemini, I focused on high-throughput microservices on .NET Core and Azure, cutting MS SQL data-retrieval time by 60% and reducing end-user latency by 25% through a high-availability backend redesign.

Right now I’m integrating AI into production workflows—building an end-to-end Retrieval-Augmented Generation assistant and shipping AI readiness and AI discovery capabilities—while working full path from domain modeling to Kubernetes deployment.
