Window ordering platform for MTO manufacturing

Challenge

In order for customers to migrate to the new version, we had to assure exactly the same ordering output as the previous system, while providing a completely revamped UX and UI. This was very critical, as we were integrating with a legacy on-prem system (CalWin) through a custom intermediary bridge.

To reduce maintenance costs and scaling limitations, the new version needed to support multiple tenants with proper isolation (custom domains, styling, configuration) on a single cloud production environment.

Lastly, to keep costs reasonable, we were looking to reuse a pre-existing advanced product configurator developer by the client for previous versions.

Solution

To avoid "big bang development", we introduced CI and CD processess to integrate and test frequently in small increments, to ensure 1:1 results with the previous system.

Since day 1, all tenant configuration was enforced through the system (without the use of tenant-specific conditional code or feature flags), which kept maintenance and devops work at a minimum.

Any reused code was encapsulate and embedded as aseparate external apps through APIs, to separate concers, keep the code clean and reduce security risks.
