Employment
Experience
- DSLR Professional Camera App for Android (Development)https://www.shopmoment.com/
I joined Moment to create the Android version of the existing iOS app from scratch. Later, I helped them build a team of remote developers to implement an exciting and complex roadmap of top-tech image processing features to take the app to the top of the charts.
Main achievements:
- Designed and built a fully Android native Camera2 API Kotlin app from scratch with core camera and video functionalities such as flash modes, timers, iso/shutter speed, white balance, and focus.
- Built a team of remote developers across the globe to tackle real-time image processing.
- Incorporated complex features like histograms, photographer analytics, and focus peaking, using low-level RenderScript and OpenGL code embedded in the app. - Web App MVP to Reverse Engineer (Development)
I was approached by an architect in Sydney who needed a way to automate real estate property investments based on government information that seemed inaccessible.
I reverse engineered the state government site to extract the information the architect needed and developed a small Django Python web app to automate the reports as an MVP. This was a short freelance engagement that gave her what she needed for her business.
