A comprehensive tech talent marketplace focused on Japan has been developed using Java, Tomcat, and MySQL, featuring 900 engineer profiles (including 40 international), active job listings, complete source code, and a database dump. The platform is operational on a VPS and is ready for transfer to a buyer's server setup. The marketplace addresses the high-demand, high-barrier Japanese tech recruitment sector, often challenging for foreign companies due to cultural and language barriers, by offering immediate market access with valuable data assets. Key components include the Java/Tomcat application, a functioning Apache and Tomcat configuration, a MySQL database with schema and profiles, job listings, and an English-admin manual for easy international operation. The system provides access to Japan's tech market, leveraging a stable technology stack, with documentation and deployment guidance available for buyers. Growth strategies for the platform involve paid job postings, expanding the developer database, incorporating bilingual features, automation, and AI-based recommendations. Although the listed revenue is $0 due to Japanese banking verification constraints, the platform contains real data. It is suited for operation without Japanese fluency as the admin manual is provided in English, and UI text is adjustable in the source code. Deployment support includes basic guidance regarding the current setup, and the platform can run on any Linux VPS supporting the necessary components.
