A system integration environment for UAT using Docker, OpenShift, and Apache Kafka for end-to-end integration of ten middle office systems for the biggest bank in the Nordics. Each of the ten systems had its own UAT environment but no integration with other systems. Because of this, mock data was used for UAT without testing the end-to-end flow and impact on the overall system.

I created the new UAT framework by taking Docker images of the testing environment for each application and hosting them on OpenShift. I enabled the data flow using Kafka message queues and set up the jobs to run on this source data to process the logic for the downstream systems, creating a near-realistic environment to test the data flow.

I wrote data flow-specific system integration tests by identifying the data source and expected output at each stage, which formed the input to the next stage and so on. I wrote tests for APIs, Kafka message queues, or Oracle Database based on the final output at each stage, using Java and Cucumber. Finally, the tests were integrated on a Bamboo CI server and the Docker scripts, which built the system to start the data flow. Then tests were triggered to test the logic as needed.

Automated testing for five media and entertainment applications slated for 4G releases on iOS and Android by an Indian telecom giant. I used Appium and the SeeTest tool to automate testing and wrote the scripts using Java, Cucumber, and TestNG.

The LTI mobile lab was set up with 90 devices, including Android and iOS platforms on phones and tablets. I delivered on the client's requirements to run automation scripts for each application on four different devices—two iOS and two Android, so our scripts were constantly running in parallel for 20 devices at any given time. This was a major accomplishment.

The device selection was configured using an orchestrator to select the required device as per the product owner's need. Our scripts ran on them consistently to test the performance of the applications and app analytics.

I contributed to a Swift-based iOS app in the eCommerce domain for a large US-based company. As the only full-stack QA, I managed everything related to the QA activities in the project. I created test plans and implemented the test strategy and automation.
