Worked with the Treasury Settlement team to modernize the settlement system used to settle treasury operations.
- Designed and implemented a REST API enabling a unified access point for derivatives TED settlement data across internal systems. Handled ~R$16MM in daily financial volume
- Led the domain modeling initiative for the Federal Bonds Settlement capability in a legacy SQL Server-based system (approx. 40 TPS, ~R$688MM/day settled), laying the foundation for solution architecture using Itaú's internal Camada Zero framework
- Proposed a future-state product vision for a self-service settlement platform, allowing internal clients to define, reuse, and share settlement profiles. Objective: Increase reusability and decouple hardcoded settlement workflows to promote domain-driven modernization.
