Backend engineer who builds distributed systems that scale

Hi, I'm Danil Lobanov. 5+ years building high-throughput backend services for real-time gaming platforms, B2B SaaS, and IoT products. I care about reliability under load, clean architecture, and shipping fast without sacrificing quality.

About

I'm a Senior Backend Engineer with 5+ years of experience building distributed, high-throughput backend systems for real-time platforms, B2B SaaS, CRM, IoT, and game backend products.

My core strength is designing backend services that stay reliable under load — .NET 8, ASP.NET Core, PostgreSQL, Redis, RabbitMQ, MassTransit, Kafka, gRPC, SignalR, Docker, Kubernetes, and observability.

When I'm not building backends, you'll find me exploring AI tools, experimenting with side projects, or studying distributed systems theory.
