This project involves the development of an Australian healthcare ecosystem called Next Practice Health Management System. The aim is to provide an innovative Practice Management System to doctors and patients in Australia. The ecosystem is divided into three main components: Patient App, Doctor Site, and Admin Site. Initially, the Patient App was part of the ecosystem. NextPractice acquired the Doctor Site, Admin Site, and the backend system from Myca Software in Canada. The Patient App includes elements such as the public website, companion app, patient app, micro-frontend bar, and its own backend, all built using TypeScript, ReactJS, and NodeJS. Integration with Helix, a healthcare Platform as a Service (PaaS), was also achieved. However, NextPractice chose to buy the system from Myca to own the technology and eventually replace Helix. The Work-Life-Health system acquired by NextPractice is a comprehensive solution for managing doctors and clinics, using technologies such as ReactJS, Java, Spring Boot, MySQL, Redis, RabbitMQ, and more. It provides functionalities for managing clinics, doctors, patients, booking appointments, consulting notes, and other essential healthcare operations.

The application supports group chats of up to 20,000 members and can handle up to 2,000,000 concurrent users.

GLAS - Meets and WeLoveChat is a Japanese dating social network designed exclusively for the Japanese market. The app is available on both the Apple Store and Google Play but faces challenges due to its mature and sensitive content. To help single individuals find friends and partners, the app combines features reminiscent of both Facebook and Tinder, providing functionalities like chatting, calling, and content sharing. In this app, gender-based interactions are facilitated: men can see women and women can see men. Users can share posts, photos, and more, allowing others to interact with them. While the app offers free features, men are required to pay for any interaction with women, and women can redeem these credits as real money.
