Professional Experience & Project Highlights:

Test and Development Software Engineer: Morgridge Institute for Research, Madison 2013 - 2017

The Software Assurance Marketplace (SWAMP) is a national marketplace funded by Department of Homeland Security that provides continuous software assurance capabilities to researchers and developers and helps to build better, safer, more secure code. The SWAMP provides the core networking, hardware, databases, and software required to support the mission of continuous software assurance. An open-source continuous builds and test software has been developed as the basis for workflow-driven continuous integration testing. Coupled with the widely deployed Condor system, an open-source workload scheduling and compute management system, SWAMP's Metronome provides a powerful and easy to use environment to support high volume continuous software assurance across a broad set of platforms that are embedded in a distributed environment. SWAMP provides the Continuous Software Assurance Lab (CoSALab) with the following popular platforms for building and analyzing software: Debian, Fedora, FreeBSD, MacOS, RedHat, Scientific Linux, Ubuntu, and Microsoft Windows.

Individual Contribution

Implemented best practices for gathering functional and non-functional specifications to derive requirements that involved brainstorming with the stakeholders use case analyses, focus group surveys, questionnaires and User observation.

Completed detailed design, and development tasks in the front end development of the SWAMP website using Java script, PHP, HTML and CSS that reflects the ever changing User Interface to enhance usability experience.

Executed functional, regression, system and integration testing using black box techniques and automated testing techniques using Selenium and Jenkins. Created and executed SQL queries and Perl jobs to validate test results and troubleshooting defects.

As the SWAMP is highly customer centric, worked with various clients/vendors in helping setting accounts, working with them by integrating their software with SWAMP, help reduce the vulnerabilities and improve the quality of their software and promote continuous assurance.

Participated in the project planning activity and lead the transition of the project Software Development Life Cycle to agile methodology, planning the sprints, defining the key roles and responsibilities and keeping track of the product backlog.

Software Engineer: Embedded Systems, Infotech Enterprises Limited, Hyderabad, India 2005 –2007

VEHICLE AUTOMATIC TRAIN PROTECTION (VATP)

The VATP is the safety critical software component of the automatic train control system managed by Bombardier Transportation. The purpose of the software is to assure that the train maintains a safe following distance, over speed is prevented and that conflicting movements are precluded. This project comprises of maintaining the existing modules and providing enhancements based on the emerging customer needs and complying with standards of regulatory bodies. New modules like vehicle alarms were developed, tested and integrated into the system. The integrated system testing is carried out using a Vehicle Automated System Tester, which simulates the wayside signals at the client’s place, Bombardier Transportation, Pittsburgh, U.S.A.

Individual Contribution

Implemented requirements gathering, prototyping, and software module development using C and C++.

Lead the complete module testing of the vehicle alarms module and the system integration testing of the module into the Train System. Performed black box testing and load testing on an automated system that simulates the wayside signals received in the actual region automatic train control.

Lead a team of 3 in performing reverse engineering to obtain an extensive documentation describing in detail how the core logic works, which is necessary for any kind of testing and maintenance activities using MS Visio and Visustin.

Implemented requirement mapping and traceability matrix into the higher level software specification, allowing for an easy verification of compliance.

GPRS Component Development for CS50

The Model CS50 is a full-featured electronic data logger/remote- telemetry unit (RTU) that can record process measurements, provide local indication, and transmit measurements/alarm status to a remote PC, control system, or other process-monitoring device. This application can be used by customers to access data from their respective field devices by polling their requests online, which is known as demand-polling. The project involves development of a GPRS component, integrate the feature into the original software for CS50 to establish communication through GPRS technology to configure the Remote Telemetry Units at a distant place and manage cryogenic tank levels. This feature is an enhancement to the original CS50 Model that already has the ability to communicate using PSTN/GSM technologies. The application also provides security of data to the customers. The feature was developed using C and MicroCOS-II.
