Danil Lobanov

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, CI/CD, observability, and automated testing.

Recently, I worked on online game backend systems including matchmaking, real-time communication, server-authoritative flows, distributed transactions, and microservice orchestration on Kubernetes. Previously, I built backend services for a European recruitment CRM and an IoT smart container platform.

I'm interested in international Senior Backend Engineer roles focused on distributed systems, platform backend, real-time infrastructure, B2B SaaS, gaming backend, and cloud-native services.
