Participation in the strategic development of the e-commerce mobile application, a true international showcase for the brand, with a particular focus on the back-end.

Main programming languages/frameworks used:

Angular/TypeScript

Nodejs/NestJs/TypeScript - PostgreSQL/KAFKA

CI/CD & Infrastructure:

Github Actions - Argo CD - Google Cloud Platform: Kubernetes/Docker

Organization: Scrum

Achievements:

1. Implementation in Clean Architecture with best practices: SOLID principles and separation of concerns best practices. This approach has made the code modular, easily testable, maintainable, and scalable, while facilitating the integration of new features.

2. Complete refactoring of the application architecture: Development of a new codebase with NX, ensuring a modular organization optimized for teamwork, without dependencies on existing code.

3. Microservice-oriented development with event-driven communication via Kafka: Design of independent microservices for each application functionality (catalog, order tracking, customer service, etc.), thus facilitating the scalability and responsiveness of the architecture. Microservices communicate asynchronously via Kafka for key events: for example, when an order is placed, a message is sent via Kafka to notify the inventory management microservice, which can then adjust available quantities in real-time.

4. CI/CD automation with GitHub Actions and deployment on GKE

5. Infrastructure monitoring with Dynatrace

6. Security and traffic management with Akamai Gateway

7. Optimization of code and shared services organization (Nx workspaces)

8. Implementation of a comprehensive testing strategy: Writing and execution of unit tests, integration tests, and end-to-end (E2E) tests.
