Developed and maintained Java-based automated test suites for fintech products using UI and API validation. Covered REST and gRPC endpoints during monolith-to-microservices migration, including business logic, permissions, and inter-service communication checks. Validated financial data via SQL queries and supported test environment operations across GitLab CI and Kubernetes tooling. Debugged integration defects by analyzing logs, CI pipeline runs, and service behavior.

Designed an internal test automation framework from scratch and delivered automated coverage for a reporting platform. Integrated automated execution and reporting into CI/CD pipelines with Allure-style visualization and quality gates. Implemented test result logging backed by database storage, and connected CI/CD workflows with Jira/Confluence APIs. Built Jenkins pipelines using Groovy and Bash, and supported ETL and validation for Hadoop-based systems while troubleshooting distributed environments.

Created UI automation projects for web and desktop applications using a maintained internal test framework. Developed automated tests for microservice systems via REST APIs for different payload formats and covered asynchronous flows backed by message queues. Reduced flaky behavior through test refactoring and contributed code reviews and onboarding for junior QA engineers. Managed build/test execution through Jenkins pipelines.

Supported release and deployment processes for banking test environments and performed post-deployment validation. Investigated and localized integration and configuration defects across applications, databases, and operating systems using log analysis. Created and anonymized test data, wrote SQL/PL-SQL queries, and implemented environment monitoring and validation automation with Bash and Windows batch scripts. Configured monitoring using Zabbix.
