KKH: Health Insurance ? I worked on this project using Kotlin Multiplatform Mobile App. Our team collaborated with KKH Health Insurance to develop this application.

As part of this project, we utilized the Kotlin Multiplatform framework to build a mobile app that can seamlessly run on both iOS and Android platforms. The app offers a range of features to KKH customers, including the ability to view their policy details, track their claims, and connect with customer support.

I played a key role in developing and implementing various features of the app, including the user interface and data retrieval system. Additionally, I worked closely with the rest of the team to ensure that the app met all the requirements and delivered a seamless user experience.

As a founding member, I am significantly involved in the ideation and progress of the startup. Additionally, as the CEO and CTO, I am responsible for the development and business area.
I developed the backend with Node.js and deployed it on Heroku. I also utilized Firebase for our authentication, integrated push notifications, and implemented the database via MongoDB. I created the web dashboard for the industry using React.js. Through this, I learned declarative programming, which is also suitable for SwiftUI. Due to our positive experiences with React.js, we decided to design our Android app on a React Native basis so that we could further develop our natively developed iOS app with React Native at a later stage.
I also did the CEO stuff, managing payments, hiring and motivating the crew.
