Commercial Opportunity Management

Context

Vibra Energia evaluated, approved and contracted new gas-station clients through spreadsheets and email. The flow moves multi-million-real contracts and is audited under SOX, so traceability wasn't optional.

What I own

I own features end to end, from refining requirements with business analysts through backend, frontend and production support:

• The approval-hierarchy saga that routes deals through commercial, credit and legal gates.
• The credit and integrity due-diligence flow.
• The contract lifecycle up to electronic signature.

Integrations

I designed the integrations the product depends on: Salesforce CRM, Microsoft Entra ID, DocuSign, SAP and external credit bureaus. That includes the failure semantics that stop a rejected external write from corrupting deal state.

Engineering conventions

I set backend conventions that CI now enforces: typed error contracts, an append-only audit trail, a transactional outbox and a migration policy. When production or pipeline failures kept recurring, I diagnosed them and turned each one into a regression test.
