I played a key role in creating and integrating the backend services that underpinned the main features of the application while I was an apprentice full-stack developer at Step In App. Creating scalable backend architectures, putting Domain-Driven Design into practice, and making sure frontend components integrated seamlessly were all part of my duties.

🟠 Backend Development: Utilized Node.js and PHP to build robust backend services, ensuring efficient data processing and management.

🟠 Database Management: Managed MySQL databases to support authentication mechanisms and maintain data consistency across the application.

🟠 API Integration: Implemented RESTful APIs to facilitate communication between the frontend and backend, ensuring smooth data flow and user interactions.

🟠 Domain-Driven Design (DDD): Applied DDD principles to model complex business domains, leading to a more maintainable and scalable codebase.

🟠 Security Implementation: Ensured secure data handling by implementing validation checks and adhering to best practices in API consumption.

🟠 Version Control and Collaboration: Utilized Git and GitHub for version control, enabling effective collaboration with the development team.
