Making a multi-site integration usable.
Following Capital One's acquisition of HSBC's U.S. credit-card portfolio, I was the lead integration architect for the contact-center work. The work included network replacement, firewall changes, desktop migration, and hardware upgrades across six acquired sites.
We brought the technology and operations teams together around a shared Master Execution Plan. Each team needed to know what would change, when it would happen, and how its work affected the others.
By reorganizing network addresses and using network address translation, we reduced the required firewall rules from roughly 4,000 to 30. That left a simpler environment for the teams to manage and change.
