Project History
Building the Entire Test Automation Framework at nCrypt
As the first QA automation engineer hired at the company, I had the opportunity to build the test automation project from the ground up. I used Selenium WebDriver with Java, TestNG, and Maven. I incorporated Log4J for logging test steps and error stack trace to a log file, and I added ExtentReports for generating a user-friendly HTML report to display the test results.
I automated all the critical and commonly-used workflows in the front-end web application, and the automation suite was run during regression testing period to reduce manual testing time and efforts. The QA team especially appreciated the fact that the automated tests replaced some of the most tedious and time-consuming manual test cases that involved number calculations and checking for the correct cash, bitcoin, and bitcoin cash balances in the customers' wallets within the application.

Building an API Test Suite to Test RESTful Web Services
At BCAA, I was involved in a data tokenization project that required web services API testing. Since no one on my team had done API testing before, I took the initiative to build the test suite from scratch. As we were a Java shop, I used the REST Assured Java framework to test the REST API endpoints.
After creating the testing framework and the initial set of test cases, I mentored another tester on REST services and the programming syntax for writing API tests. The project was a success, and the entire test suite was run on a daily basis in Bamboo, our continuous integration tool.

Leading the QA Activities for a Brand-new Government Agile Project
I was hired as a test lead and QA automation engineer for a brand-new Agile project at a government agency. The project's purpose was to redesign and rebuild the intranet so it could function as a collaboration and knowledge-sharing platform for employees.
After some discussions with the development team, we decided to build the test automation project in Python because it was the language that the majority of the developers was comfortable with. I built the test automation framework from scratch using Selenium WebDriver and automated the tests for all the new features that the developers produced in each sprint.
In addition to building the entire test automation framework, I also mentored junior testers, set up, and configured test management and defect tracking systems, performed accessibility testing for the hearing-impaired, and created the test strategy document for submission to the senior management.
The Agile project we worked on served as a pioneering example for other departments within the organization, and we frequently had colleagues visit our office to learn how we used the Agile methodology to deliver our project incrementally and successfully.

Serving as a Mentor in UBC's Computer Science Mentorship Program
Since 2006, I have been volunteering as a mentor in the computer science mentorship program at the University of British Columbia. This program allows me to give back to the computer science department while providing guidance to students concerning the direction of their coursework and careers. Not only have I found this experience to be rewarding, I have also made some lifelong friends over the years.
