Circles Life Mobile and Web App

Led and managed the workload for 14 team members who were distributed across several geographies and supported the manual and automation testing of web and mobile app features in three regions.

My responsibilities included project management, release train management for all microservices and weekly release product features, and testing and sign-off so that all new features were pushed into production in a timely manner before the end of the sprint. I was also responsible for RCAs for any post-production issues and for setting up processes to avoid future issues related to the learnings from the RCAs.

Arcesium Post-trade Management System

Led 15 team members and was accountable for delivering the entire project. I was initially responsible for the manual testing activities and later created and drove the regression automation roadmap for the entire platform. I also researched the available test automation tools (Selenium WebDriver, Katalon Studio,, and Robot Framework) and drove the selection of the best tool to meet the organization's needs. Finally, I was involved in developing and maintaining integration tests for the different applications involved in the entire platform, both manually and through automation.

PropertyGuru Apps

Oversaw the manual testing of eight iOS apps for PropertyGuru before they were released in four countries. I increased the testing efficiency by co-creating a custom BDD framework for mobile iOS automation using Cucumber on Swift in Xcode. I developed another framework to automate API testing, prepared the feature files and step definitions, and led the implementation for all the test cases in BDD using Gherkin.
