TL;DR
Cloud Genii improved a Salesforce Marketing Cloud environment that was slowing campaign execution and limiting reporting visibility.
The work focused on the operating layer behind customer journeys: journey setup, dynamic configuration, conversion tracking, WhatsApp preference handling, reporting data and monitoring.
The strongest evidenced improvement was that journey build and testing time was reduced from 3 months to 3 weeks.
Overall, the environment became easier to manage, easier to measure and better aligned with day-to-day campaign execution.
