Work Experience:

Sr Software Engineer Apple Inc, Cupertino, CA May 11-present

Working on a new scalable server side service for iOS devices.

Cofounder iNumbr Jan 08-Dec 08

Developed a website, in part-time, with a friend in the area of consumer VOIP telephony, which managed

to reach 400,000 users. The website allowed consumers to obtain free, disposable phone numbers that

route calls to their personal phone, and thus allow them to maintain privacy when needing to reveal phone

numbers in non-private settings like craigslist, ebay, matrimonial/dating websites, etc We also sold our

solution to a few businesses, earning annual revenues over $100,000.

Sr Software Engineer IV Cisco Systems, San Jose, CA Feb 05-Apr 11

Worked on several complex systems projects in the general area of Platform Software in a business unit

dedicated to making Mobile Internet gateways like GGSN, PDSN, LTE, Wimax, etc. The role involved

intricate system design and development (often at product architectural level), complicated debugging

through a large codebase, in an important role while showing leadership in several technical areas in the

team. The main language used was C, and some assembly. Work included:

Development of software running on Intel IXP network processor in the data plane of the product

to process packets optimally at high speeds in a multi-core and multi-threaded architecture with

both parallel and pipeline designs, requiring low-level coding that extracted most computing

power off the processor architecture.

Worked on porting and bringing up Cisco IOS and Linux operating systems on a new hardware

platform, a complex system involving several processors (Intel IXP, MIPS, PowerPC, Xscale

ARM, Nitrox, etc) and several custom FPGAs/CPLDs. This provided experience in kernel

bringup, hardware/processor initialization/configuration/architecture, Linux kernel powerpc

platform code, device drivers including Ethernet driver, bootloaders, networking protocols, etc.

Also developed offline diagnostics software for the board.

Developed numerous platform features for our product, including linux user-space device driver

infrastructure, multi-threaded health-monitoring software, statistics and control protocol software

on QNX operating system, control packet prioritization in linux network driver, etc.

Provided leadership in all things Linux in the team, and assisted in bigger picture work like

analyzing linux operating systems within cisco to identify useful components, evaluating software

architecture options for next platform (virtualization of IOS on Linux, etc)

Software Engineer Paypal (eBay Inc), San Jose, CA Mar 04-Oct 04

Worked on implementing new product features in C++ and SQL in a Apache/Oracle/Linux

environment within an industrial-strength code base of a scalable, reliable, multi-tiered, multi-

component website that impacts more than 50 million customers.

Worked on Paypal s industry-leading anti-fraud system with features like implementing anti-fraud

card models, address authentications, third party communication in XML, client-servers, etc.

which required understanding of web protocols and skills in programming at application, database

and network levels; and involved working closely with other engineering, product, content,

design, QE and other groups in the product development lifecycle.

Software Developer (Internship) Lightline Software Inc, Palo Alto, CA Aug 03-Dec 03

In an exciting fast-paced Storage Security startup, worked on storage system software involving

kernel programming in FreeBSD UNIX, with major features being:

Designed and implemented non-volatile caching in FreeBSD UNIX ATA/IDE disk device driver.

Wrote a simple volume manager used to form a higher capacity logical volume by doing software

RAID Level 0 over existing hardware RAID Controller (3ware Escalade) storage units.

Developed a configuration system consisting of a Java Applet front-end and Perl back-end.

Developed a client-server system with a simple communication protocol.

Assisted creation of a stack of pre-allocated inodes in the file system.

Research Assistant (Part-time) Prof. Massoud Pedram, EE Dept, USC Jun 02-Aug 03

In a team of two, ported Linux kernel to an XScale-based embedded system, which involved

modifying low-level details like configuration of memory controller, PCI bridges, interrupt

routing, and device drivers of PCMCIA, etc.

Implemented a power manager in Linux kernel for an embedded system, using a dynamic power

management algorithm to shut down devices. Modified device drivers of PCMCIA and IDE.

Programming Projects: (University Requirements or Personal projects)

Implemented an ad-hoc wireless network of embedded systems: Implemented Ad-hoc Positioning

System which involved forming an ad-hoc network of embedded Berkeley motes and

implementing a communication protocol so as to perform localization using hop-based distance

estimation. Used C on TinyOS embedded operating system with resource constraints and low

wireless network reliability.

Parts of Nachos Operating System: Implemented core parts of Nachos Operating System, an

instructional operating system - thread synchronization, virtual memory, file systems, and

multiprogramming. Used C++ on UNIX.

Built a Peer-to-Peer Network File System: Developed a distributed file sharing system using peer-

to-peer mechanism (like Kazaa). Used C++ on UNIX.

Retail Website: Developed a retail website with frontend in Perl/PHP and backend in Java/MySQL

Computer Virus in MS-DOS (Personal): Developed a self-encrypted, polymorphic computer virus

that self-replicates by infecting MSDOS executable files. Used x86 assembly language.

Othello-playing computer program (Personal): Developed a program that plays Othello, a strategy

board game. Uses Artificial Intelligence Game Playing algorithms. Used VC++ on MS Windows.
