Legacy System ReST API Development

When your Windows client/server system needs web application access

The Legacy Client/Server Problem

Your business runs on Windows client/server applications that work well internally, but:


  • Desktop-only access - No web or mobile application capabilities
  • Limited remote access - Staff can't work flexibly from any device
  • Integration barriers - Other systems can't connect to your data
  • Modernization blocked - Can't move to web applications without an API layer


You need a professional ReST API to bridge your legacy database to modern web applications.
