Work Environment
A mature VB.NET and Oracle codebase that has been in production for over 15 years.
Limited existing automation, offering significant opportunity to add value through modernization.
Predominantly manual deployment processes transitioning toward automation.
Windows-based infrastructure supporting a high-availability production system.
