As an Senior Software Integration Architect, I spearheaded a major project to structure and modernize a healthcare plan linked to the largest national oil company. I constructed and ensured the entire lifecycle of a cloud-based bus tailored for secure, manageable, and highly available integrations. This initiative stabilized and modernized legacy applications into a .NET-based architecture on Azure, leveraging event-driven paradigms like Azure Service Bus. I conducted monthly post-implementation cost and stability monitoring, ensuring the effectiveness and longevity of the solutions I designed and supported.Achievements:Achieved >99.5% uptime for systematic integrations.Implemented over 80 monitored REST APIs.Architected and developed a critical integration handling over 4 million medical guide events, successfully migrating the entire back office and ensuring 99.99% payment accuracy of over $70M to plan stakeholders monthly.Created a .NET 6 - C# 9 integration with multiple APIs to process millions of medical guides monthly, integrated with SAP Business One for seamless payment processing.Ensured the total cost of the new ecosystem did not exceed 80% of the initially estimated values, despite incorporating new integrations and handling millions of new requests.Designed and developed an entire ecosystem of APIs for centralized notifications and messaging via WhatsApp and SMS using Twilio broker.

- Definition of good practices, technologies and architecture for integrations between systems- Gathering requirements for integration between systems;- Preparation of integration designs;- Construction of an integration environment and the Bus;- Development of systemic integrations based on Microsoft and Azure technologies;- Development of APIs based on synchronous and asynchronous messages;- Execution of unit and integrated tests;

As a Senior Software Engineer, I was recruited to lead the phased development of Open Banking for a bank serving over 4 million customers. My primary challenge was to expose a regulated Restful API with standardized security, ensuring software quality and code reusability while abstracting complexities and applying design principles such as SOLID and Gang of Four.Key Responsibilities:Developed APIs using .NET 5 and C# 9.Thoroughly studied the Open Banking documentation.Conducted legacy information mapping using AutoMapper, transforming it for Restful API exposure (REST in its purest form).Securely exposed services mandated by the central bank to other banks via microservices.Implemented robust logging via AWS Kafka.Managed deployment to Staging and Production environments through Jenkins pipelines.Demonstrated proactivity and automation passion by automating various tests using Postman Collection, ensuring visibility for stakeholders.
