PROFESSIONAL EXPERIENCE
PTC (Parametric Technology Corporation),Greensburg,PA (www.ptc.com) November 2010 to Present
Senior Software Engineer
 Worked on new features of Windchill X26 and X24 using Java and JavaScript programming languages and
Eclipse and IntelliJ IDEs. Also, created unit and integration tests. Windchill is an enterprise Product Lifecycle
Management software (PLM) which uses such technologies as Spring framework,Google Web Toolkit (GWT),
JavaScript.
 Added new features and worked on existing features of Windchill Quality Solutions (WQS) software (formerly
known as Relex), using programming languages, tools, and platforms like C#, C++, SQL Server,Visual Studio
2013, Silverlight 5, Windows Communication Foundation (WCF), .NET 4.5, Visual Studio Performance Profiler.
WQS is an enterprise software used by big companies to monitor, and improve the reliability of products,
services, processes or software applications. The software is a client/server application (uses WCF and Web

2. 2
services),and has a number of modules, which can be licensed separately for different tasks. The software has a
desktop version (i.e., the client application is installed on client machines and is written in C++ and WPF),and a
web version (i.e., the client application is a Silverlight application, which can be started by opening a web page
using a web browser like Internet Explorer or Firefox).
 Participated in development of most recent releases of the software (Relex 2011, WQS 10.1, WQS 10.1, WQS
10.2, WQS 10.3, WQS Athens,WQS Berlin). Among other things, worked on FRACAS, FMEA, Fault Tree
Analysis modules, graphing, conversion, audit trails, Import/Export, filtering, reporting modules as well as on
many other features.
 Used Visual Studio load testing tool to measure the WQS performance under stress,when hundreds of clients
make simultaneous WCF calls.
 Worked on integrating ThingWorx (internet of things application) with Windchill Quality Solutions (exposing
WQS API in ThingWorx).
SRA International, Inc.,Morgantown, WV (www.sra.com) October 2008 to November 2010
.Net C# Programmer (Software Engineer II)
 Duties included improving and adding new features to the Spirometry Longitudinal Data Analysis software
(SPIROLA). The software was being developed for the National Institute for Occupational Safety and Health
(NIOSH),the client of the SRA International, Inc., and it is used by physicians for evaluating the workers with
potential lung problems. Also, occasionally performed data analyses using SAS 9.0 software,and MS Access
software.
 Re-programmed the entire code of the software from scratch in a more efficient way,using good object oriented
programming design and added new features,which were included in the next release of SPIROLA (SPIROLA
V2.0). Also, worked on the documentation for SPIROLA V2.0. The SPIROLA V2.0 software can be freely
downloaded at http://www.cdc.gov/niosh/topics/spirometry/spirola-software.html.
New features in SPIROLA V2.0 among others include:
 Windows forms for designing multi-level questionnaires (intervention plans) in which each question can
have any number of sub-questions. The information about the questions, and the control types used for the
questions (i.e., textbox, combo-box, radio-button) is stored in a database, and is not hardcoded.
 Modules for printing reports, generating charts, filtering out the workers in a risk list (i.e., workers which
might have lung problems).
 Developed the next version of SPIROLA (SPIROLAV3.0). Also, worked on the documentation for SPIROLA
V3.0. The SPIROLA V3.0 software can be freely downloaded at
http://www.cdc.gov/niosh/topics/spirometry/spirola-software.html. Some of the new features of SPIROLA V3
are:
 SPIROLA V3 can be used by physicians to send requests for worker lifestyle and safety interventions to
worksites (in the form of special format files, opened by SPIROLA software). These requests are completed
at worksites and are sent back to physician’s office, where SPIROLA loads the information in received files
into SPIROLA database.
 SPIROLA V3.0 allows designing customized questionnaires, which are saved by SPIROLA as PDF format
files (both questions and font style of each question can be customized using SPIROLA V3.0). After these
questionnaires are printed and are completed by participants, the questionnaires can be scanned into PDF
files and can be automatically loaded into SPIROLA database by SPIROLA V3.0 (SPIROLA V3.0 retrieves
participant answers in questionnaires, which can be analyzed using statistical tools). Note, SPIROLA V2.0
had only designer for intervention plans, and didn’t include designer for questionnaires. Also, the designer
for questionnaires and intervention plans in SPIROLA V3.0 has more features than the designer for
intervention plans in SPIROLA V2.0.
 SPIROLA V3.0 can load the data from various types of databases, such as Microsoft Access databases,
Microsoft SQL Server databases,ODBC-compliant databases. Also, SPIROLA V3.0 can load the data from
spirometer databases, which have a format different from SPIROLA database format. SPIROLA V3.0
users can develop assemblies in any .NET language following the guidelines provided in SPIROLA V3.0
user manual. These assemblies can be added to SPIROLA V3.0 using the SPIROLA interface, and will

3. 3
automatically convert the custom format data to SPIROLA format data on the fly (i.e., data is read from the
spirometer database directly, without storing the data to some temporary SPIROLA format database). Note,
SPIROLA V2.0 allowed loading only data in MS Access databases in SPIROLA supported format.
West Virginia University,Morgantown, WV (http://depts.hre.wvu.edu/tltc) May 2005 to October 2008
College of Human Resources and Education (HRE)
Graduate Assistant (Information Technician Assistant from January,2008 to October 2008)
 Duties included: designing MS Access 2003/2007 and MS SQL Server 2005/2008 databases; developing active
server pages; maintaining the college’s servers and workstations; setting up and maintaining Active Directory on
the servers; providing technical help to faculty and staff; other technical assignments.
 Designed MS Access 2007 database with good user interface for storing and querying the information about the
computers in the college.
 Exported large MS Access 2003 database into MS SQL Server 2008 database, so that the MS Access file is used
as a front end interface, while the database is managed by the MS SQL Server 2005. Set the permissions, masked
the sensitive columns using user defined functions, views, triggers, and added stored procedures for performing
some administrative tasks.
 Set up Active Directory and DNS Server on two of the college’s servers, and programmed a VB.NET application
using Visual Studio 2005 and a number of VB scripts to set some settings on the lab and classroom computers
added to the domain. The scripts and the VB.NET application were configured to run on the workstations using
active directory group policies, and executed at workstation startup and user login. Also, developed applications
using .NET languages (VB.NET, C++/CLI) to troubleshoot servers (e.g., client/server application for detecting
which ports are blocked by the firewall, an application, to retrieve a word file from the SharePoint database, and
some other applications).
 Designed MS SQL Server 2005 database for the Speech Pathology and Audiology department. The database was
used by the students and faculty to enter the evaluation data about the speech and audiology clients:
 Integrated the database with MS Access 2007, so that users use the interface of MS Access on client
computers to view/modify the MS SQL Server database.
 Implemented column and record level permissions using database triggers, SQL views and Active Directory
and SQL Server user accounts and roles, so that each user can only view and modify records and/or
columns, which relate to the user.
 Programmed a number of SQL stored procedures for different tasks among which are automatic user
account creation, periodic database backups, and database activity logging.
West Virginia University,Morgantown, WV (http://www.wv-hsta.org) May 2006 to Aug.2006
Health Sciences & Technology Academy (HSTA)
Active Server Pages Programmer
 Designed Active Server Pages (VBScript/JavaScript) for viewing and modifying the information about students
and employees, stored in large MS SQL Server 2000 database (contains several thousands of student records).
Each user belongs to one of the five user categories and can only view and/or modify the data, which the
corresponding category users have permissions to view and/or modify.
 Used sophisticated techniques, such as storing the metadata about the database tables in application variables, for
efficient data validity checking and html control generation (i.e., replicated code is avoided).
 Used JavaScript to perform most of the data processing on the browser on client computers, and to avoid
reloading the entire content of web pages from the server after every modification to the database (i.e., only
information about the modified fields is sent to the server, and browser reloads only small amount of data from
server, showing if the modification was successful or not).

DISSERTATION
 Dissertation Title: Heuristics for the Dynamic Facility Layout Problem with Unequal Area Departments.
 Developed number of improvement type heuristics (e.g., tabu search, hybrid tabu search and simulated annealing,
hybrid genetic search and tabu search (memetic heuristic)), for solving the static and dynamic facility layout
problems (SFLP and DFLP) with equal and unequal area departments, using C++ language.
 Developed efficient boundary search constructive heuristic for solving the DFLP with unequal area departments.
The technique solves the problem in a very short time, and is used in tabu search heuristic.
 Developed efficient dual simplex algorithm for solving the DFLP with unequal are departments, which exploits
the structure of the problem to find the solution in less number of simplex iterations. The algorithm is used in tabu
search heuristic (the moves are performed by changing the right hand sides of the simplex tableau and re-
optimizing the tableau, instead of resolving the problem from scratch).
 Developed an efficient tabu search, and hybrid genetic search and tabu search heuristics (i.e., memetic heuristics)
for the DFLP with unequal area departments. The heuristics use the boundary search constructive heuristic and
dual simplex algorithms, and outperform the techniques available in the literature on both static and dynamic
facility layout test problems.
 Used C++ Builder 6 to code the algorithms and a user friendly interface.
