Case Study: Large European Client Company achieves JEE-based, multi-tenant SaaS Lab Management solution with Happiest Minds

Re-engineering a Power Builder Application to JEE based SaaS Enabled Application for a Large European Client

Happiest Minds worked with a large European client to re-engineer a legacy PowerBuilder lab management application into a modern, multi-tenant SaaS solution. The challenge was to migrate a 2‑tier desktop system to a scalable, cloud‑ready JEE web application while maintaining functionality and accelerating delivery.

The team re‑architected the application to Java/HTML5, designed it for cloud hosting and multi‑tenant SaaS delivery, and used automated code analysis and Scrum to speed development. The result was a fully web‑based JEE solution, reduced implementation complexity, faster iterative releases, and a SaaS offering ready for deployment.
