About
I'm a software engineer with 4+ years of experience building robust backend systems and scalable applications. My expertise lies in designing payment and billing systems, high-concurrency architectures, and real-time communication platforms.
Currently, I'm focused on building enterprise-grade billing systems at ONDO LLC→, where I architect solutions that handle complex payment workflows and transaction processing at scale.
In the past, I've had the opportunity to work across diverse domains — from telecommunications at Unitel Group building VOIP and SIP/RTC communication systems, to creating crowdfunding platforms and agentic AI solutions. I also contributed to CMMS development for IkhGobiEnergy LLC, a major local mining corporation.
I hold a Bachelor's in Computer Science from the National University of Mongolia, where I also served as an instructor teaching software engineering principles.
