Served as a Back-End Developer Trainee specializing in Node.js, with a focus on building scalable, secure RESTful APIs using Express.js and MongoDB. Gained hands-on experience with JWT authentication, role-based access control (RBAC), and database design using Mongoose.

Contributed to real-world projects—including user management and booking systems—where I applied MVC architecture, clean code principles, input validation, error handling, and API security best practices to deliver reliable, maintainable backend solutions.

This diploma provided in-depth training in backend development using Node.js, with a focus on building scalable and efficient server-side applications. The program covered modern JavaScript (ES6+), asynchronous programming, and the use of Express.js to develop robust RESTful APIs.

I gained practical experience implementing authentication and authorization (JWT), working with middleware, and applying effective error-handling strategies. The course also included database integration using MongoDB and Mongoose, enabling the creation of full-featured backend systems.

Throughout the diploma, I completed multiple hands-on projects that strengthened my real-world backend development skills and improved my ability to architect reliable server-side solutions.

This diploma provided comprehensive training in core frontend technologies, including HTML, CSS, JavaScript (ES6+), and Git. The program emphasized building responsive, user-friendly interfaces using React.js, with a focus on state management, component-based architecture, and modern development practices.

The coursework also introduced Next.js for server-side rendering (SSR) and enhanced application performance. Throughout the program, I completed multiple hands-on projects that strengthened my practical skills and improved my ability to develop clean, efficient, and scalable frontend applications.

This certificate reflects a solid foundation in C++ programming, with a strong focus on Object-Oriented Programming (OOP), Data Structures, Algorithms, and Design Patterns. The course covered core concepts such as encapsulation, inheritance, and polymorphism, along with the implementation of key data structures including arrays, linked lists, and trees.

It also introduced essential algorithms like sorting and searching, as well as common design patterns such as the Singleton and Factory patterns. The program included hands-on projects that strengthened my practical coding abilities and improved my ability to write clean, efficient, and well-structured code.
