Work Experience

QA Automation Engineer

2022 - 2024
Toptal
  • Worked on a project to isolate existing services into a new microservice. I documented all existing functionalities and then performed full regression testing, ensuring no un-documented issues after the migration.
  • Migrated the company's existing end-to-end tests framework from Cucumber to Playwright, improving speed with asynchronous testing.
  • Documented and maintained all existing functionalities in detail in non-technical language to allow product managers to comprehend and rapidly request changes easily.

Experience

Service Isolation and Test Framework Migration Project

This project involved isolating a core service into a new microservice to improve modularity. I documented all existing functionalities to ensure a seamless migration, capturing every detail before performing comprehensive regression testing. This meticulous approach allowed me to verify that no undocumented issues surfaced post-migration, ensuring the reliability and accuracy of the new service.

As part of enhancing the testing framework, I also migrated the existing end-to-end tests from Cucumber to Playwright, which resulted in significantly faster test execution due to asynchronous testing capabilities. This change improved testing efficiency and boosted test reliability in the CI/CD pipeline.
