01 /About
I'm a backend developer from Lalitpur, Nepal, who likes the unglamorous parts of software: the payment gateway that has to reconcile, the legacy service that has to move to .NET 8 without breaking, the logistics workflow that has to price an order correctly every single time.
Across fintech, HR, logistics, and consumer audio products, I've learned that most hard problems aren't solved by clever code. They're solved by understanding the system first, then making the smallest change that's clearly correct.

How I approach a problem
➜ ~ understand --domain --constraints
Before touching code, I learn the business rule behind the ticket and who feels the pain when it breaks.
- ✓Map how money moves before changing a remittance API
- ✓Learn the pricing rules before automating logistics workflows
- ✓Ask what "done" looks like for the client
