About Me

I hold a Bachelor's degree in Software Engineering from the National University of Mongolia — completed in 3 years with a 3.8 GPA, building a strong foundation in software architecture, algorithms, and system design.

Currently working as a Full Stack Developer at Capitron Bank, leading a team — architecting and delivering large-scale ERP systems, the core banking platform, high-traffic customer-facing web applications, and AI/ML integrations from the ground up. Driving technical decisions, designing system architecture, and shipping complex production-grade software used by thousands of banking customers daily. Previously engineered fullstack solutions at SSudalgaa.

Passionate about API design, Backend systems, Frontend development, and AI/ML. I thrive in collaborative environments, love leadership roles, and pick up new technologies fast.
