As professionals in application development, we continue to do research every day in order to meet customer business needs and provide the highest quality service.

Easy Back End system development

The development team is responsible for the Back End system of the application, and possibly also for designing and developing databases and APIs, as well as setting up an environment for servers using AWS concurrently.

Pengembang Sebelah focuses on managing project team management with internal resources, rather than relying on external resources.

In addition to assigning several technicians to develop Android/iPhone applications, directors, designers, Q&A services, and even sales to handle exclusively application development, every knowledge possessed by each is accumulated, and the knowledge of each individual is shared across the team and matters. This is reflected in every project that is done.

In addition, we develop supporting applications, and have strengthened the development system without outsourcing it to the offshore development that is currently being used.
