Becoming a complete service marketplace
The number of service categories has grown from 15 to more than 450, with a wide range of customers using our services for both private and business purposes. With more than 2.2 million registered members, the company needed a new brand image as it continues to diversify in various aspects of its services.

The company would like to make Coconala the first place people come to when they want to ask someone to do something or use someone else's skills.
The company intends to retain the "friendliness" and "easy to use" impression of the existing Coconara. In addition, the new brand identity will be a brand with diversity that "offers a full range of services" and a sense of trust that "can be used in all situations," from private to business use.

As a result, the architecture, infrastructure, and databases that support them are extremely challenging and difficult to build.
In addition to the core Coconala service, services such as “Coconala Assist” and “Coconala Professional" have been created, and the number of users from various positions, including both individual and corporate users, is dramatically increasing, making back-end development more and more important by the day.
