Smith Micro Inc,

Chicago, IL

Description

The QuickLink Media Video Delivery Platform delivers highly

optimized video to hundreds of current handheld mobile devices.

Responsibilities

- Tested and troubleshooted QuickLink Media Video Delivery

Platform for Network Bandwidth Adaptive Streaming

- The assignment gave a very deep understanding of QOS (Quality

of Service) and SLA (Service Level Agreement)

- Developed a proto type for testing Adaptive Streaming

- Developed Test Cases and performed functional and regression

testing for for hundreds of wireless devices

- Tracked all the defects/bugs using a defect tracking system

called Test Track Pro

ACADAMIC

PROJECTS Video Compression Environment:

Visual C++, MS Windows XP

- A closed loop video compression algorithm has been

implemented that produces scalable compressed video

elementary streams from a raw (RGB) Video Stream.

- The Algorithm includes a Macro Block based compression

mechanism which is similar to MPEG-2 standard of video

compression

Image Compression Environment:

Visual C++, MS Windows XP

- Built a system that reads an image file in RGB format and

converts it to YUV space and HSV space. Implemented various

methods of sub sampling and Quantization on Y channel.

- Implemented Lossless encoding methods such as LZW coding,

Huffman coding. Implementing Lossy compression methods such

as Vector Quantization.

- Encoded images into JPEG and JPEG2000 formats using Discrete

Cosine Transforms (DCT)

Multimedia Authoring tool and Player Environment:

Visual C++, MFC, and MS Visual Studio

- Implemented a Video authoring tool that is used to include

image on the video during scheduled time intervals

- The player implemented with the functionality to synchronize

and render a raw (RGB) video stream and a raw audio stream in

a way that MPEG-2 does.

Automated Worm Finger Printing in Linux Kernel 2.6

Environment: C, Fedora 10

- Implemented a Firewall in Linux Kernel 2.6 to implement a

Automated worm-fingerprinting algorithm

- The System was implemented using Net Filter as kernel module

Operating System Development Environment:

C, C++, Solaris

- Designed and implemented a synchronized, multi threaded

grocery store. Implemented locks and condition variables to

develop Mutual Exclusion and Thread Synchronization

- Designed and implemented System calls such as wait, signal,

fork, Yield and Exec for mutual exclusion.

- Tailored Virtual Memory for Nachos by developing TLB, Page

table, Inverted Page table and swap file. Implemented Remote

procedure calls for the system calls.

Configuring CISCO Routers Environment: Fedora

8, GNU/Zebra Toolkit

- Configured BGP on Cisco 7000 and Cisco 4000 series routers to

analyze Persistent Route Oscillation

- Configured Black holing, Sink holing and Trace back for

regulating DDos(Distributed Denial of Service) attacks

- Analysis of TCP flow behavior and Service Differentiation

using FIFO and RED disciplines

Network Simulation Environment:

Ethereal (Wire shark)

- Simulated and evaluated Ethernet (shared and switched), Token

ring, RIP and OSPF using OPNET

- Analyzed protocols such as HTTP, TCP, IP and ARP using

Ethereal (Wire shark)

Client-Server Application Environment:

C, C++ and POSIX Threads

- Designed and implemented a Multi Threaded, Multi Process

based client-server system with multiple clients that routes

the fragmented messages over TCP and UDP sockets in a network

- Data packets were framed, packetized and routed across the

network along with acknowledgements for the received data

packets

E-Commerce Website Environment:

XHTML, PHP, MySQL and WebServices

- Designed and developed a Web-based Information System for an

online retailer.

- Built a Shopping cart for the website using session variables

and MySQL database.

- Implemented security for the e-commerce website using session

variables and AJAX.

- Supported the website on server side using PHP, Perl/CGI and

Python scripting

Geographical Information System, USC-map Environment:

Java, KML and Spatial features of Oracle 10g

- Designed and Developed a graphical monitoring system for

security personals to monitor people and buildings within the

range of the alarms

- Application was designed to execute spatial queries like

range, nearest neighbor and display the results over a

Graphical User Interface (GUI), USC Campus map

XML and XQuery

- Developed a database using XML and validated using XSD.

- Queried the XML database using XQuery. Presented the results

using XSLT
