What I'm looking for

I’m looking for a team where I can modernize and scale mission-critical .NET backends—microservices, cloud integrations (AWS/Azure), and strong testing/performance. I’m open to remote work and like strict SLAs.

I’m a Senior .NET Developer with 7 years of experience building and modernizing backend systems in financial services and enterprise software. I specialize in C# and .NET, and I focus on shipping reliable production services under real-world constraints.

My work often centers on microservices architecture, including CQRS and Clean Architecture with DDD. At AccessBank Azerbaijan, I built the IPS integration to Azerbaijan’s Central Bank real-time payment network, handling secure payments within a strict 5-second SLA.

In recent roles, I modernized legacy .NET Framework systems to the latest .NET stack, introduced Clean Architecture with DDD, and containerized core services with Docker. I’ve also delivered measurable impact—like upgrading legacy CRM connectors from .NET Framework to .NET 7, reducing median processing time from 1.5 minutes to under 15 seconds.

I bring a strong engineering culture around testing, performance, and maintainability. I’ve worked across AWS and Azure integrations, designed concurrency-safe Redis caching, and used unit/integration/BDD (SpecFlow) approaches to reach 90%+ code coverage.
