Tasks: Design, build, and maintain robust automation frameworks for REST APIs, microservices, and asynchronous message queues. Leverage modern AI tools and LLMs to generate synthetic test data, optimize test coverage, and automate test case creation for complex backend logic. Utilize deep analytical and debugging skills to isolate, reproduce, and resolve complex distributed system issues.

Advanced proficiency in SQL queries, data validation, database schemas (PostgreSQL) and testing complex data pipelines. Practical experience leveraging AI-powered dev/test tools (e.g., GitHub Copilot, ChatGPT) to accelerate script generation, generate edge-case test data, and optimize backend test suites. Proven track record conducting performance and stress testing on backend services using tools like JMeter, Grafana k6, or Gatling.
