# Edgar A. Dikenge

Edgar A. Dikenge is a Software Engineer based in Luanda, Angola (WAT / UTC+1), specializing in pragmatic software architecture, API security, enterprise integrations, backend platforms, idempotent financial flows, and API-led architectures. He champions choosing software patterns based on real trade-offs: from well-bounded modular monoliths to BFF layers over legacy cores and event-driven architectures.

In an era dominated by rapid AI development, Edgar emphasizes Security by Design (OAuth2/JWT authentication, input sanitization, data encryption, RBAC, signed webhooks, and OWASP compliance) as a mandatory foundation for all production software.

Edgar currently serves as a Software Engineer at Nossa Seguros, designing secure BFF layers over legacy insurance core systems (Cleva) using MuleSoft, integration pipelines in Azure DevOps, and idempotent payment processing.
