Enterprise solutions and API security for Vivo Brazil.

In this period, I designed end-to-end enterprise solutions across CRM, ordering and digital platforms. The initiatives had a combined project value of US$4M and were all successfully delivered, with my contribution spanning architecture and delivery support.

I translated business requirements into functional, technical and integration designs and worked with business and delivery teams to prepare solutions for implementation.

For Vivo Brazil, I designed and delivered API security solutions covering SOAP and REST APIs, translating security requirements into implementation-ready technical designs.

• Led client scoping workshops and requirements discussions.
• Produced high-level and detailed design documentation.
• Aligned integration architecture, performance and operational readiness with delivery teams.
• Contributed to the successful delivery of the initiatives designed during the period.

All initiatives in the referenced portfolio were successfully delivered. The US$4M figure is the combined value of those projects, not the standalone value of the API security work.

This overview does not publish client API configurations, security controls, endpoints or implementation details.
