Structured CV

Backend developer with government and legacy-system experience.

C#/.NET backend developer with experience in public-sector systems, modern backend ownership, and large legacy codebases that still had to ship.

Profile

I am strongest as a backend developer, but my useful range is wider than endpoint implementation. I have worked through domain modeling, data access, authentication, CI/CD, legacy desktop clients, deployment constraints, and public-sector systems where the shape of the problem mattered as much as the framework.

Core skills

  • C# / .NET
  • ASP.NET APIs
  • PostgreSQL / SQL Server
  • EF Core / ADO.NET / Dapper
  • Authentication and authorization
  • CI/CD and Docker
  • Legacy .NET Framework / WPF / WCF
  • Backend architecture and domain modeling

  • Ported a Latvian National Archive service backend from an obsolete internal template to a newer CQRS/MediatR-based template while preserving API contracts where possible.

  • Extended a JSON-driven call scenario engine and generated schemas for safer scenario authoring.
  • Built .NET task-runner payloads, including address-data import from PostgreSQL replica into SQL Server with A/B slots and minimal interruption.

Legacy PHP/web full-stack foundation across local business websites and a larger car-parts wholesale platform.
