The Namoosori Coaching Program is a meticulously designed course for aspiring software developers who aim to excel in their careers.

Conventional education often focuses on immediate job skills that align with corporate requirements. Unfortunately, even universities are now emphasizing practical training for employment over foundational knowledge. Our program is designed to foster engineers who can solve real-world business problems and derive satisfaction from their work. We hope the Namoosori Coaching Program will be the starting point for this aspiration.

The traditional apprenticeship system, where a master guides a disciple through repetitive practice, is the most time-tested method of engineering training. Software development, being an engineering discipline, requires not only theoretical education but also intensive hands-on training under expert coaches. Modern software education tends to emphasize knowledge transfer while neglecting practical training. This is partly because educators are not always practitioners and due to societal pressures for quick results. Most graduates lack sufficient coding experience, having written fewer than 10,000 lines of code, leading to a precarious grasp of knowledge and uncertain practical skills.

There is a misalignment between the skills companies seek in software developers and the training provided by educational institutions. This often results in graduates entering the workforce without the essential capabilities needed for long-term engineering careers. The Namoosori program focuses on fundamental skills that will serve developers throughout their careers. Our unique training methods include writing nearly 200,000 lines of code, clean coding practices, and personalized coaching. The program is structured into fourteen Gates to assess understanding and proficiency. If a learner fails a Gate, they get retest opportunities, but failing three times at the same Gate requires starting over. After a rigorous 30-week course, participants emerge as capable developers ready to tackle any project.

Our coaching team consists of "education-dedicated coaches," who are professional instructors, and "training-dedicated coaches," who are seasoned developers. Depending on the situation, specific coaches are assigned to guide learners through different periods. Whether one coach handles all periods or each period has a dedicated coach, our approach ensures personalized, optimized guidance for each learner. Coaches also help identify learners' talents and introduce suitable development fields.

Not all participants will complete the course. Those who do will possess a thorough understanding of object modeling, data structures, algorithms, networks, threads, and UI events, and will be proficient in coding these concepts. The most critical skill for graduates is self-directed learning, enabling them to quickly acquire and apply new technologies.

Over 30 weeks, participants undergo 14 Gate assessments and write nearly 200,000 lines of Java code. The program aims to equip learners with the foundational skills needed for long-term engineering careers. All courses are self-directed, supported by coaches and the namoosori.io service system. The program does not cover database, web, and framework-related technologies, as companies prefer hiring engineers with solid foundational skills.

The Namoosori Coaching Program has been piloted offline for five years, applied in corporate new employee training, and Nextree's new hiring. The curriculum has been enhanced with subjects like Crosswalk and Timestable, which have been conducted multiple times, and projects like the Telegram clone, which received positive feedback. Practical coding-based data structures and algorithms have also been added. The coaching process has been verified, and service and content development are ongoing.
