About the service

I develop reliable server-side applications on C# and the .NET platform — at the level used to build enterprise systems. I specialize in backends of web applications and HTTP APIs that carry real business load: order processing, billing, reporting and internal tools. I pay attention to clean architecture, predictable behavior under load and code that a team can maintain years after launch.

The project covers the entire server-side cycle. I design the domain model and database schema, implement data access through Entity Framework Core, deliver documented REST endpoints with validation and role-based access. I add background services and scheduled tasks for queues and notifications, connect third-party integrations — payment providers, CRM, messengers — and cover key scenarios with unit and integration tests.

Deployment is part of the work, not something left for later. I set up configuration, logging, health checks and containerized deployment, prepare migrations that safely run on production data, and deliver clear documentation. Need a new system from scratch or a rescue of old code — I'll build a backend that's stable, secure and ready to grow.
