Played a key role in designing and delivering scalable Azure-based backend services for a large-scale B2B ordering platform, contributing to payment orchestration and event-driven architecture to ensure reliable processing of business-critical transactions, while collaborating closely with architects and business stakeholders to translate complex functional requirements into secure and resilient technical solutions.

Azure Cloud & Event-Driven Architecture:

• Developed and operated .NET / C# microservices deployed on Microsoft Azure (PaaS).
• Implemented event-driven communication using MassTransit with Azure Service Bus.
• Used queues and topics to manage order lifecycle events and decouple backend services.
• Applied retry policies, dead-letter queues, and idempotent message handling.
• Used Azure Cache for Redis, Azure Storage Account, and Azure Key Vault.
• Designed services to support horizontal scaling, asynchronous processing, and fault-tolerant communication patterns. 

Payment Integration & OMS / PSP Orchestration:

• Delivered backend integration of a payment solution in a B2B ordering context.
• Integrated Sogenactif (Société Générale) with Worldline as PSP.
• Implemented asynchronous messaging between the Ordering system (OMS) and the PSP to manage payment state transitions (authorization, capture, transaction lifecycle management).
• Implemented secure webhook processing integrated into asynchronous workflows. 

Security & Authentication:

• Implemented OAuth 2.0 / OpenID Connect?based authentication patterns.
• Enforced JWT-based authentication and authorization across APIs.
• Integrated a dedicated security microservice responsible for token validation and claims enrichment. 

DevOps & Code Governance:

• Managed source code using Azure DevOps, with one repository per microservice.
• Implemented CI/CD pipelines per service with multi-environment deployments.
• Developed shared internal NuGet packages for cross-cutting concerns.
• Implemented unit and integration tests; monitored applications using Datadog. 

Led the definition and implementation of the software architecture for a medical teleconsultation platform, establishing development standards and best practices while guiding the engineering team in delivering secure, scalable, and maintainable backend services. Oversaw application lifecycle management and CI/CD processes to ensure structured and reliable software delivery.
