At Грэйпсити Монгол ХХК, I developed backend APIs and new features for the МОСТ payment platform using Java, Hibernate, JPA, and Maven, and made Angular updates. I also integrated APIs for two banks’ corporate gateways and three mobile operators.
For a new loan module, I worked as a systems analyst on a five-person team, handling requirements, process flows, API specifications, task allocation, and code reviews. I also optimized Oracle and PostgreSQL queries and supported deployments in Jenkins and Red Hat environments.
