Backend Development

Power the Logic Behind Modern Web Applications

The Backend Development Course at OILab (Open Innovation Lab) focuses on building the server-side logic that powers modern web applications. Backend developers create systems that manage databases, handle APIs, process data, and ensure applications run smoothly and securely.

This course teaches students how to design scalable backend architectures and develop powerful APIs used by modern web and mobile applications.

At OILab, students learn backend development through real-world applications, learning how to connect servers, databases, and APIs to build complete systems.

The course includes modern backend technologies such as Node.js, Express.js, REST APIs, authentication systems, database management, and server deployment.

By the end of the course, students will be able to build powerful backend systems and manage application data efficiently.
