• Worked on customizing several android core framework components such as Media-player, DRM framework service and native frameworks (Stagefright), Window manager, Activity manager and other UI components.
• Developed an android application for a I.O.T smart light device (a product by an IOT start-up), and had various features such as controlling the light intensity, color based on various parameters such as weather conditions, manually set color alarm etc as well as manually adjustable.
• Designed and developed a data collection android application used by real-estate agents for collecting images of properties along with their absolute geo-locations.
• Worked on a POC project for customizing the window management of Android for giving a desktop like, floating multi window user experience. The project included building customized AOSP source tree and developing an android application to demonstrate the same.
• Experience in integration of android core framework components (Media player and DRM framework, Activity manager and window manager services.) with platform specific stacks.
• Well versed in Android SDK, core framework components and application design methodologies.
• Strong experience in using Android development and debugging tools Android Studio, AVD, adb etc.
• Experienced in integration of cloud services such as Amazon S3, Cognito, Google firebase and consuming REST APIs from android applications. Using open source libraries such as Retrofit, Butter knife, Dagger and Google android architecture components.
• Developed and worked on Low level embedded systems projects which involved developing bare-metal and RTOS based applications, device drivers.
• Strong understanding of Machine learning and Computer vision algorithms also experience with ML frameworks (Tensorflow, Pytorch, OpenCV etc).
• Experience developing scalable web-application back ends and REST APIs using javaScript (NodeJs), Python (Flux) consumable by mobile and web applications.
• Knowledge of multimedia streaming protocols and technologies such as MPEG DASH, Microsoft Smooth streaming and Apple HLS.
• Familiar with AWS services such as S3, Cognito, RDS etc
