    Hi. orem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Since our establishment in March 2019, we have successfully supported multiple startups in developing, launching, and maintaining their systems.

We have seen many promising startups struggle due to poorly built systems that are difficult to operate. Our team ensures that every project is built on a strong foundation with a focus on three key areas: planning, architecture, and development. - Planning: We assist in refining business ideas into well-structured service plans while ensuring the system's core framework is properly established. - Architecture: Our lead architect with 26 years of experience has designed major national-scale projects for Samsung, Hyundai, SK Telecom, and the National Tax Service, ensuring optimal data management and system scalability. - Development: Our team consists of skilled developers who have been working together for years. We specialize in React, Next.js, Vue.js, React Native, iOS/Android native development, and backend technologies like Java, Node.js, and database management (Oracle, MySQL, MariaDB). We believe that a well-planned, well-architected, and well-developed system is the key to a startup's success. Our partnership doesn’t end after development—we provide ongoing maintenance and operational support to help businesses thrive. 🚀 If you're looking for a reliable technical partner to build and scale your business, let's connect!
