GIPHY: GIF/Sticker Keyboard and Maker

https://play.google.com/store/apps/details?id=com.giphy.messenger
I built the Android app for Giphy.com, enabling users to browse and search the GIF, sticker, and clip catalog or create their GIFs and stickers. I contributed in particular to the clip browsing and creation parts.

I implemented the sticker maker functionality and new features like image filters, augmented reality, layering tools, and cropping tools for creation. I also enhanced some existing features like captioning, which enabled our users to create quality content that could be used and shared anywhere.

AudioNow Digital Applications

https://www.audionowdigital.com/
At AudioNow, we developed a framework for creating mobile applications for radio stations. After three iterations, we delivered a complex framework that helped us build and maintain more than 350 applications for Android and iOS. Using the framework, we created applications using simple templates and implemented UIs and content updates on the server-side without updating the app in the stores.

I was tasked with designing the framework, leading the mobile team, and implementing the Android version of the framework.
