About

I am a backend engineer at CityTech in Kathmandu, where I lead the backend implementation of a new Merchant Portal — contributing to architecture and service design, writing PostgreSQL functions for settlement processing, and keeping high-volume financial reporting queries fast.

I joined as a Java Backend Intern and grew into an Associate Software Engineer over roughly a year. Before that I worked on applied machine learning at AMNIL — speech processing, document translation and liveness detection — which still shapes how I approach problems.

I work mostly in Java and Micronaut on the platform side, and in Python with FastAPI, PyTorch and Streamlit when I am building something with a model behind it.
