Challenges and Solutions

Communication would be the first point that had to be addressed. The Client was based in a time zone different to our software developer, while the Vietnam Central Bank team worked from a different time zone to the two other parties.
  • Knowledge transfer from main development team
  • Communication with technical specialists from VCB
During development the team faced several network related issues restricting access to servers even via VPN, high ping between our office and the remote servers.
  • Proposed network access configuration tweaks to Vietnam technical team
A major challenge was the software application’s monolithic structure, which was difficult to support, maintain, and interoperate.
  • Engaged in minor code refactoring
  • Introduced modular architecture and microservices where possible
  • Introduced new connector modules and new data transfer protocols


Smart IT’s software developer made substantial input in implementing the following solutions on Vietnam local servers:
  • Integrating Instant Funds Transfer (IFTS) System
  • Integrating Account Clearing House (ACH) System
  • Establishing efficient communication between all system components
