About
I'm a software engineer based in Kathmandu. I've been writing Python professionally for over three years, mostly on the backend, and I currently work on payment systems at Khalti.
Before Khalti I was at Naxa, building backends for geospatial products: PostGIS queries, vector and raster tile pipelines, and a few gRPC services. Before that I spent a little over a year at Aarawan Tech working on real-time chat, notifications and multi-tenant Django apps.
On the AI side I work with LLM applications, retrieval-augmented generation, embeddings and agents. What interests me most is getting them to behave reliably inside real production systems.
