Work Experience
[Managed Delivery] QA Engineer
Garn Enterprise (Hong Kong) Limited
- Developed test plans and test scenarios for the web application similar to a well-known eCommerce app. I actively participated in user stories refinement sessions, asking many questions to clear out the expected behavior.
- Carried out manual testing and test automation of the features developed for the app. Used Testsigma for test case management and test automation. Created MySQL procedures and queries in order to prepare testing data or to actually test the features.
- Used Jira as the ticket and bug tracking tool.
Senior QA Engineer
Fertility related clinics
- Tested a web application and related services for the fertility clinic(s) built on Ruby on Rails and JavaScript/TypeScript, running in the cloud (AWS).
- Conducted functional and performance testing of multi-service web applications, including feature and regression testing.
- Handled day-to-day communication with developers, development leads, product owners, and sometimes with medical staff directly.
QA Consultant

- Introduced a scrum-like development process with official sprints using Jira as a monitoring tool.
QA Automation Engineer
Data Science and Analytics Automation Platform
- Set up GitLab runners and created a GitLab pipeline for running existing automated tests using an in-house test runner, PowerShell, and Node.js.
- Tested and verified fixes by following the current workflow of development lifecycles. Verified on multiple versions of the application under test and documented in great detail what was tested.
- Created a POC for a test automation framework using Pywinauto and Pytest for testing the localization of the application under test. Introduced some new ideas that could be tested from the i18n point of view.
