The Challenge
FinCore's 12-year-old Java monolith could not scale beyond 500 TPS and had 14-day release cycles.
Our Solution
Decomposed into 18 microservices, adopted event-driven architecture with Kafka, and implemented blue-green deployments.
“B4Visionaries transformed our engineering culture. We went from fear of deployments to deploying 10 times a day with confidence.”
