@alexeysokolov

I build high-load .NET backends for trading platforms and external integrations.

At B2Broker, I build backend architecture for B2Trader, a multi-asset trading platform. I shipped AI-powered chat and LLM features, improved peak RPS by approximately 10×, led the FIX Protocol track, and designed the initial Market Data architecture.

Across telecom and technology products at VimpelCom and Inline Pro, I've delivered .NET microservices, web backends, external integrations, and data-import systems. I work with C#, .NET, ASP.NET Core, SQL, PostgreSQL, and distributed-system components to build reliable systems that scale.
