As part of the foundation team for the M4 project, I contributed to the development of a mobile platform that allows users to control music playback in bars via their mobile devices. My main responsibilities and achievements include:* A/B Testing and LaunchDarkly Integration: Assisted with integrating LaunchDarkly into the platform to enable A/B testing experiments, improving feature flag management and real-time decision-making capabilities.* High-Concurrency Testing: Designed and executed integration tests using JUnit5, WebClient, and TestContainers to validate high-concurrency scenarios, ensuring platform stability under load through reactive programming.* End-to-End Test Automation: Developed and maintained automated test suites using Pytest to provide end-to-end testing coverage across the system.* CICD Pipeline Setup: Helped set up and maintain Jenkins pipelines for continuous integration and delivery (CICD) across development, staging, and production environments. Integrated Dynatrace to monitor system performance in AWS, ensuring smooth deployments and real-time performance tracking.Key Skills:Test Automation, A/B Testing, CICD, AWS, LaunchDarkly, Dynatrace
