We used a phased implementation strategy to address the project’s compliance and usability concerns. Initially, we placed a high priority on creating a terminal selection feature that would allow staff members and agents to select the closest terminal for card swipes and transaction completion. In addition to streamlining the payment procedure, this also made sure that the project’s crucial requirement for strict adherence to data security regulations was met.

We integrated database schema updates into the deployment process, allowing for seamless updates to Oracle and Postgres databases as part of the deployment process.

To manage secrets securely and comply with compliance requirements, we developed an audited, team-administered authorization solution using Vault. This solution integrated with T-Mobile’s existing LDAP systems, enabling teams to manage their secrets while ensuring isolation from other team’s data.

Alongside technical implementation, our team facilitated a cultural shift within T-Mobile’s IT organization. We educated teams about modern DevOps best practices, including Infrastructure as Code, the 12-factor app methodology, testing pyramids, configuration management, and containerization.
