About me
C#/.NET developer with more than 10 years of commercial software development experience. I specialize in backend systems, enterprise CRM platforms, REST APIs, integrations, and complex business logic — working with both legacy .NET Framework projects and modern .NET 6–8 applications. My experience covers building systems from scratch, evolving existing products, designing architecture, optimizing SQL queries and stored procedures, building background processing pipelines, and integrating with third-party services. I've worked with MS SQL Server, PostgreSQL, Docker, Linux, and GitLab CI/CD. I'm comfortable getting up to speed in an unfamiliar codebase, clarifying requirements, and taking a task through to production. Open to remote work and project-based collaboration. I operate as a registered sole proprietor (individual entrepreneur) in the Kyrgyz Republic.
