Mobile Application Developer

A calorie and macro tracker with a built-in barcode scanner. No account, no subscription, and it works offline. I designed, built, and shipped it on my own.

I built the complete platform behind Kokoro Audio's dramatized audiobooks: the kokoroaudio.com storefront, the listening app on both stores, the admin panel, and the Firebase backend with its cloud functions.

Modernized a maternity support app by migrating it from bare React Native to Expo, upgrading the stack, setting up EAS for builds and releases, and optimizing performance on both platforms.

Quick Parent is a hybrid mobile application built using Ionic and Angular. I joined the project to resolve critical issues related to in-app purchases and optimize the app's overall performance and reliability. My contributions ensured a seamless user experience by fixing major issues and improving the codebase, resulting in a more efficient and stable application.

Led end-to-end development of a free app for strengthening relationships between parents, delivering a stable cross-platform experience with Firebase data and automated push notifications.

Led the design and development of a free parenting app offering research-based tips, with a smooth cross-platform experience on iOS and Android and Firebase-powered push automation.

In collaboration with a Singapore-based education company, I took over the development and maintenance of a mobile application designed for students to post their homework and assignment questions, similar to StackOverflow. Tutors could answer questions and provide additional paid tutoring services. When the app came to me in 2017, it was built with an outdated version of the Ionic framework and Angular 2, presenting numerous bugs and performance issues. By 2018, I led the complete redesign and redevelopment of the app, introducing new features, modernized designs, and improved usability. I continued to actively maintain the app and provide support for bug fixes and feature updates until 2022.
