Kathmandu, Nepal 🇳🇵
I build and fix .NET systems that are already carrying real traffic. I came into development through QA and database administration, so I care more about production behavior than clean abstractions. Remote friendly, and open to architecture, .NET modernisation, search, and performance work.
