Over the past three years, I have played a key role in developing and maintaining two core mobile applications at DoctorTool: DoctorTool Nakes (for clinical use) and DoctorTool Mobile (for patients). In the first year, I successfully built both applications and contributed to a notable public health initiative by deploying DoctorTool Mobile as a screening tool for new students at Universitas Indonesia. In the second year, I took full responsibility for publishing and maintaining both apps on the App Store and Play Store. I also mentored an intern over the course of a year and improved the screening experience in DoctorTool Mobile, which helped increase its user rating to over 4.5 stars. My efforts were recognized with a promotion to Senior Mobile Developer. Currently in my third year, I’m expanding my technical scope by stepping into backend development, particularly in managing databases and backend services. I continue to lead mobile development for both DoctorTool Mobile and DoctorTool Nakes, while also mentoring a junior developer who was previously an intern. Most recently, I successfully implemented PIN and biometric authentication, enhancing both the security and convenience of the login process.

I was actively involved in the development and enhancement of the mobile application, consistently working to improve its performance and user experience. I implemented new features that aligned with product goals and user needs, contributing to the app’s overall functionality and usability. In addition to mobile development, I also handled various backend tasks, including web data crawling, optimizing API performance, and maintaining the database to ensure data integrity and system reliability. I provided ongoing support and maintenance, addressing issues promptly and ensuring the application remained stable and up-to-date across releases.

I actively contribute to the development process by consulting on and creating features related to third-party notification systems. I’ve also been involved in implementing the delete account feature to support user data privacy. My responsibilities include identifying and fixing both minor and major bugs across the application to ensure a smooth user experience. In addition, I regularly perform testing on both Android and iOS platforms to validate functionality and stability. I participate in pull requests, conducting thorough code reviews to maintain code quality, and collaborate with the team through daily scrum practices to ensure alignment and progress in ongoing development cycles.

I was responsible for building accessibility features tailored for both admin and store users to ensure a smoother and more inclusive experience. As a full-stack developer, I created and implemented all core functionalities of the stock management system. These features included integrating real-time data synchronization using Firebase Realtime Database, developing search and filter functionality for viewing stock, implementing input and output stock tracking, and enabling users to filter and search stock recap reports. This end-to-end development ensured a responsive and efficient stock management solution.
