Experience

iOS App UI Automation

For the Swift-based app for retail, I was the Senior Test Automation Engineer and started working on the iOS UI automation for a retail app at a very early stage, and it took me 14 hours to complete. I optimized the automation, added nodes for pipelines, reduced its execution time to one hour, and made it part of the continuous integration. Moreover, I was able to automate another app from the ground up and made an automation switch between apps on the same simulator.

TLD Registry Web and Automated Testing

A website for domain registration at Afilias. I was the QA Analyst and performed manual testing on the website, including regression, functional, end-to-end, and sanity testing. I also worked on adding tests to the web automation, using Java, testing, and selenium, including finding the selectors and xPaths for web elements.

3.1 Million TLD migration [Guinness World Record]

In Afilias, as an intermediate QA Analyst, I worked on testing a SQL script for migrating 3.1 million top-level domains from Australia's database to the Afilias database. I used Postgres to write queries and automated the tests to compare and verify the data was migrated correctly. I indexed tables and created views to optimize the script. While testing the script, I helped the developer optimize the SQL scripts and lower the execution time. On the migration day, I started at 2 AM, verified the data, and gave a green signal to the team for migration, and we finished at 5 PM.
