Acted as a back-end developer, leading a team of 10 members to build an application with 50+ microservices.

This platform has the following features:
• Connects over 1,000 organizations to have secure communication over an API with REST and SOAP protocols.
• Provides single sign-on (SSO) to support 7000+ active users to log in to their partner platforms from a single place.
