On this project, I added Google Analytics to improve user engagement. Used AI tools on a daily basis, such as Claude, Cursor, and Devin for PR reviews. Also, I made sure the production version of the app was stable. I fixed bugs and optimized render cycles to improve user behavior and analytics metrics.

CopilotIQ
https://mycopilotiq.com/CopilotIQ is a shared-code web and mobile application that enables patients to communicate with doctors through the Twilio Video SDK while providing access to charts and medical data. The platform also includes a web admin where nurses can view patient information and manage patient calls.
I built the mobile application from scratch for Android, iOS, and web. The main challenge was supporting multiple platforms, screen sizes (phones, tablets, and desktops), and accessibility settings such as font scaling, since the platform was designed for older users. I implemented Twilio Video calling across Android, iOS, and web, as well as push notifications, CodePush, and Google Analytics. I managed CI/CD pipelines and mobile store approvals, contributed to the React-based web admin, and implemented caching techniques using AWS CloudFront.

Fairmarket Home
Fairmarket is a revolutionary platform for homeowners and contractors. However, it is not just a platform; it is a powerful, full-range, deeply personalized home improvement and management app, the first of its kind.
My role in this project was to improve the existing mobile app in React Native. I added a 3D engine to the app to render the user's house and let the user tap which part of the house needs repair. I used Google Analytics, code push, added QA (automated tests), and used AWS Device Farm for this. I also managed App Store and Play Store submission.
