Overview

A real-time commodity exchange built to stamp out theft and irregularities in Mongolia's mining sector by moving trades onto an audited, fully transparent auction floor.

I designed the architecture and led fullstack development of a modular monolith where every order, match and settlement is logged and periodically archived. The platform passed an external audit and was tested jointly with the Mongolian Stock Exchange and the Financial Regulatory Commission.

Since launch, the system has executed over $200 million in deals - my first major product delivered end to end, from requirements to production.

Highlights

  • Real-time auction interface handling live bids from competing brokers, fanned out over AWS SNS.
  • ISO-compliant, security-hardened backend verified by an external audit.
  • Non-functional requirements delivered in full: periodic archiving, operation logging and disaster recovery.
  • Tested jointly with the Mongolian Stock Exchange and the Financial Regulatory Commission.
  • Led the development team from requirements through production deployment.
