  • PSTech | Cisco Jabber Test Automation

    I set up automation infrastructure from the ground up using Jenkins. For this project, I've automated all the tests in multiple teams, that were run manually before. This required setting up test environments using Cisco unified collaboration servers, designing and developing test methods in C# and using FitNesse to write test scripts.

    I also created a mechanism for automated result publishing used by the teams and product managers to gain insight into the current product quality.

  • PSTech | Cisco Jabber Development

    I designed and developed new features for collaboration application in C++ using Visual Studio environment. This included writing unit tests using GTest and the GMock framework.

  • MathWorks | Simulink Project Builder Form In-memory Graph

    I designed and developed a test tool in Java for creating Simulink projects from their in-memory graph representation. I also wrote unit tests for the tool. I made the code extensible and applying design patterns to fulfill high coding standards.

    The tool was used by team members and automation tests to create Simulink projects with desired dependencies between files easily.

  • MathWorks | Improved Component Build Infrastructure

    I designed improved build infrastructure by automating all the steps that required manual intervention. This included introducing myself to GNU Make to write new and improve existing makefiles.

    I also wrote unit tests in MATLAB to cover the project. This project required working with other teams and giving technical support while they switch to new build infrastructure.

  • MathWorks | Improving Automation Tests

    I worked as a technical lead for this project; the goal of the project was to have testing done along with documentation like readability.

    This required designing and writing Hamcrest matchers that could be reused across the project with custom failure message that is easy to understand. The results were easily readable and understandable tests, with test conditions that read like natural language sentence. This also reduced time when investigating test failures as the failure message was clean and specific
