Experience

rTribe Counseling and Community App

rTribe Counseling and Community is a mental health and wellness app that connects users with professional counseling services and a supportive community.

As the sole iOS developer on the project, I was responsible for building and maintaining key features, including developing a robust chat feature from the ground up. Additionally, I streamlined the deployment process by integrating Fastlane into the workflow, enabling automated builds and faster releases.

Student Planner

I developed a native iOS app from scratch, allowing users to personalize their faculty schedules. The app parses schedule data from a web page, displays it, and enables users to customize their schedules by moving or removing classes. To ensure a seamless and personalized experience across devices, I used Firebase to store and sync user modifications.
