Progress Slowed Without Experimentation
Every product experiment required a full code change, QA cycle, and deployment. This meant that rapid iteration was effectively impossible. At the same time, backend logging had grown into a patchwork of incompatible implementations across services, making cross-service debugging and incident response difficult as well.
New Systems Built From the Ground Up
Trio engineers embedded directly within the bank’s teams and delivered a server-driven experimentation platform powered by Contentful, allowing the product team to launch and modify A/B experiments entirely through the CMS without touching application code, and they standardized observability.
