Apr 2010 – May 2016 · 6 yrs 1 mo · Redwood City, California

• Joined company on day 1, when naturally 0 lines of code existed. Helped grow engineering team from 4 to 25. Spearheaded design of Tely end-point software architecture. Design re-organized the code base to (1) "common" code for multiple generations of Tely hardware and (2) hardware-specific media libraries that are invoked by "common" code. New design avoids code duplication, enhances maintainability, and simplifies birthing new generations of Tely hardware.
• Made several contributions as a highly skilled individual contributor. For example,
• invoked hardware H.264/H.263 video encoding/decoding via OpenMAX as well as Android MediaCodec API
• interfaced H.264 and H.263 video with various video calling protocol stacks
• built several prototypes via Android app development
• implemented wireless desktop sharing (a.k.a. screen sharing) in various use-cases: in various flavors of video calls, out-of-call as a local projector
• designed, architected, and implemented Tely's proprietary group video calling (a.k.a. multi-party video calling). Now known as "telyCloud" videoconferencing service.
• implemented Skype functionality in the product through Skypekit API
• interfaced H.264 video with Skypekit
• worked on rendering graphics, including transmitted videos on the screen
• implemented several features end-to-end, for example, for "Contact Search": overall flow design, getting results through Skypekit API and displaying results on the screen
• Skills: C/C++; Java; multi-threaded programming; Android JNI; OpenGL; shaders using GLSL; NAT traversal using STUN, TURN & ICE; AES encryption; Android APIs for video encoding/decoding/rendering & muxing such as MediaCodec, GLSurfaceView, MediaMuxer; Networking socket programming; Android screen capture and sharing using MediaProjection API;

• Built a proof-of-concept demo for interactive TV with virtual pan/tilt/zoom functionality. A video of the demo can be seen here:

• On a prior visit in April 2007, helped design and implement a controlled network test-bed for fair head-to-head comparison of different P2P video streaming systems.

• My research focused on video streaming with interactive region-of-interest (IRoI). High-spatial-resolution videos offer the possibility of viewing an arbitrary region-of-interest (RoI) interactively. The user can pan/tilt/zoom while watching the video. This allows watching user-selected portions of high-resolution video even on displays of lower spatial resolution, e.g., mobile and hand-held devices. In the case of remote streaming, IRoI avoids transmitting the entire field-of-view in high resolution, thus reducing required data rate.
• For an example, visit the ClassX webpage of Stanford university to see how this technology is enabling low-cost publishing of lecture videos while providing an enhanced user experience:

Jul 2003 – Sep 2003 · 2 mos · Munich Area, Germany

• Analyzed a scalable video coding proposal and possibility of integrating the same in a bigger project at Siemens Corporate Technology.
• Built a transcoding library for streaming 3D wavelet coded video.

Feb 2003 – Apr 2003 · 2 mos · Munich Area, Germany

• Software Development on an Analog Devices Mobile Chipset (ARM 7 based wrist phone Core) for interfacing with a DAB (Digital Audio Broadcasting) module. The wrist phone (developed fully at Siemens) is a fully functional GSM mobile phone in a wrist watch.
• Development and implementation of the MMI (Man Machine Interface) for the above.
• Integration of applications running on the wrist phone Core with an
• external Virtual Keyboard (VKB).
