At Smile.com.au, I worked as a solo developer on the Australian dental health platform, designing, developing, and shipping app builds. I integrated OCR and camera SDKs for document scanning and real-time data capture.

I also implemented Firebase crash reporting, analytics, performance monitoring, and release monitoring. I added OneSignal push notifications and Branch.io deep linking.

At GoSquire, I led a team of four, designed the initial architecture, and developed the mobile app. I built TaxiBooking, News, and Radio services using Uber APIs, New APIs, and Radio APIs, and added Redux Persist caching.

At Anyone, I individually led mobile front-end design, development, and deployment, including an audio-calling feature using Agora.io. Earlier, at BenzingaPro, I worked with a team to develop the app architecture and add real-time stock data, news, and streaming; at Glixen Technologies, I worked on DWT from scratch and designed its structure to be dynamic and scalable.
