PROFESSIONAL EXPERIENCE

LitePoint, Sunnyvale, California April 2008 – Present A startup company building wireless test equipment Senior Software Engineer

Design and develop software for a GUI application to configure and capture data from wireless test cells and display analysis results. The wireless tester supports testing of various wireless protocols such as LTE, WCDMA, GSM, WIFI (11a/g/n), WIMAX, BLUETOOTH, FM and GPS.

● Worked in a group of 5 developers. Performed tasks of attending product review meetings, gathering requirements, software design and development.

● Design and develop GUI for wireless test equipment using HTML5/javascript/jquery for front end, and tomcat server/Java servlets, C++ libraries as backend technologies.

● Designed and developed the application to collect the data from the wireless test equipment using a back ground thread and display the data results real time on a C# GUI with embedded MATLAB based and C# based plotting controls. Used C++ dll’s to interface with data analysis software, middleware and firmware components.

● Developed cross platform tcp client interface routines using open source C++ socket library. The library is used by instrument driver to communicate with embedded server residing on test equipment.

● Interfaced with the technical writer to develop the product documentation.

● Interfaced with QA engineer and provided them with necessary documentation for performing serviceable testing.

Yahoo Inc., Sunnyvale, California April 2007 – April 2008 A leading Internet services provider.

Senior Software Engineer

Developed C++ and Perl applications to collect, merge, filter and project data from various data warehouse feeds and publish the data to scoring servers that score the user interests in various categories (such as Finance, Autos) using Behavior Targeting Models. The application uses shmproxy proprietary messaging service to publish the messages from the data filtering server to the scoring server. The platform used was 4.6 Free BSD UNIX.

● Worked in a group of 10 developers. Performed tasks of gathering requirements, software design and development.

● Used Yxf clustering and parallel batch processing framework to develop a system capable of processing and publishing around 3 to 4 million messages per hour.

● Implemented features such as automatic failover in case of a server/process failure, load balancing by controlling the number of events processed per second.

● Provided the QA and Operations team with necessary documentation and instructions to perform the end to end, load and performance testing of the system.

● Used Agile/Scrum software development methodology with shorter software development life cycle.

APL LIMITED, Oakland, California Sep 2005 – April 2007 A leading Liner and Logistics company.

Senior Analyst / Lead RFID Developer

Developed C++, C# .Net and Visual Basic based warehouse logistics applications with functionality to download purchase order information, generate advanced shipment notice, print and scan shipping barcode labels.

● Worked in team of 5 developers. Performed tasks of code review, software design, software development and assign work among developers.

● Developed C++ Active X control to synchronize data between Windows XP based desktop warehouse application and Windows CE based Pocket PC scanner application using Microsoft Active Sync Remote API interface.

● Developed C# .Net application for warehouse scanning using .Net compact framework 1.0. The scanning application runs on a Symbol Pocket PC loaded with Windows CE 4.2 operating system.

● Led the development and implementation effort of a RFID slap and ship solution. The solution was implemented at APL warehouse for Net Gear customer in compliance with Best Buy mandate. The Zebra R110xi 300 dpi printer was used to print the RFID smart labels. Mohan Bollapragada Page 3 of 4

SEAGATE TECHNOLOGY, LLC, Milpitas, California Oct 1995 – Sep 2005 A leading manufacturer of disc drives for PCs and servers. Senior Staff Engineer / Lead Developer

Led the development effort for several C, C++ and Visual Basic applications for networking, wireless communication, and real-time data collection and analysis in a 24/7 disc drive manufacturing environment. Assumed ownership of the system, with responsibility for system maintenance and improvement, in 1998. Many of these applications were part of a system for tracking Radio Frequency Tags (RF Tag) attached to batches of manufactured disc drives. These applications were used for automated Work In Progress tracking, Resource tracking and Key Process parameter tracking.

● Gathered business requirements through telephone conversations and meetings with customers and colleagues.

● Developed program specifications such as sequence diagrams and class diagrams using object oriented design tools.

● Wrote simulation programs to emulate machine inputs and outputs for testing the various application modules.
