Senior Software Engineer, backend and .NET modernisation

Senior software engineer in Kathmandu with 4+ years shipping .NET for insurance and enterprise. I own reliability and modernisation for an insurance platform of 50 .NET projects on Kubernetes: structured logging and tracing across old and new services, the plan off end-of-life .NET to .NET 10, and the fix for socket exhaustion across ~390 call sites.

Selected impact

  • ~390Ending socket exhaustion across the platform. The error class disappeared from production logs, and outbound HTTP now has one place for retries and tracing.
  • 1 IDOne trace from gateway to database. One correlation ID now follows a request end to end.
  • 61%From end-of-life .NET to .NET 10. A sequenced roadmap with known risks; the first services already run on .NET 10.
  • v16A public website on Next.js 16. Shipped to production with a tested rollback path.
  • 4A release standard people follow. Releases are predictable enough to schedule.
