Building intelligent systems at the intersection of machine learning and software engineering. Specializing in computer vision, semantic search, and production-ready AI solutions.

01. About Me

The Story So Far

I am a software engineer turned machine learning specialist, currently based in Ulaanbaatar, Mongolia. My journey began with frontend development, but my fascination with intelligent systems led me deep into computer vision and natural language processing.

At the Institute of Mathematics and Digital Technology, Mongolian Academy of Sciences, I spent over two years building and deploying ML models — from image classification to semantic search powered by fine-tuned embedding models.

Today, as a Data Scientist at XacBank, I bring research rigor to the financial sector — finding patterns in data that drive business decisions.
