Monolith to Microservices for HR Platform
Enterprise HR Tech Company
The Challenge
What we were up against
A 12-year-old Java monolith serving 50,000 daily users was reaching breaking point — weekly deployments, 8-second page loads, and a growing list of features the team was afraid to build.
The Solution
How we solved it
Incremental decomposition using the strangler fig pattern. Extracted twelve bounded contexts into independent microservices while the legacy system continued serving production traffic.
Results

Zero downtime during entire migration
