Experience
Elderly Care Native Mobile Application
A React Native application for hiring healthcare companions.
I was the lead front-end developer in a team of three and liaised with the back-end developer to implement the APIs needed to populate the rich information available throughout the app. I used proper typings in TypeScript with Apollo GraphQL, Redux, Socket.io for chatting, Google Maps for live location tracking, and Facebook and Google SDK for login and signup.

Chat App in React
A web chat app that integrated with Microsoft Teams. The app allowed users to chat with their contacts which could be created, along with contact groups and contact lists.
I was the front-end developer and used HTML, CSS, React, Redux, and other libraries to create this app. The back end provided a REST API which I integrated into the web app and created a Redux-based architecture with thunk, slices, and selector.
The app was integrated into Microsoft Teams and allowed users to log in via their SSO feature.

Family Management
A React Native application for managing the education, health, and entry passes of family members. In this project, four applications are in use via families, doctors, teachers, and security guards.
The project was being developed by a team of over 30 people, and I was the React Native developer in charge of managing the four apps. The apps were all based on a Redux toolkit-based architecture—slices, reducers, and selectors—with a REST API client created via Axios.
Multiple doctors in the USA are using the apps to manage their patients and appointments.
