I build .NET backend integrations, authentication services, and B2B travel platforms.

At MixVel, I develop and maintain hotel-booking integrations, improve JWT authentication, and build B2B airline ticket sales features using the NDC protocol. I also develop backend services for a mobile application with .NET, PostgreSQL, RabbitMQ, and Kafka.

Previously at Itransition Group, I built full-stack web applications across risk management, employee qualification accounting, and fuel accounting. My work included authentication, new and existing feature development, external-service integrations, and test coverage.

I’ve also rebuilt a game monetization WPF client at tvx games and delivered payment-system integrations, betting-registration integrations, and a major website rewrite at Элисофт. That work included balancing payments across external providers and expanding product capabilities.

Earlier at Neolant, I developed WPF and Silverlight applications for document management and geospatial services, including map-based object and relationship processing. I work across C#, ASP.NET Core, SQL databases, messaging systems, frontend technologies, and automated testing.
