Automation using TypeScript Playwright:

• Creating automated tests from scratch
• Managing a large E2E test suite (approx. 3,000 scenarios)
• Integration tests
• Internal services integration
• WCAG 2.1 AA accessibility testing
• Email service integration
• Visual testing – baselines stored on AWS S3, downloaded on demand (lightweight repository, low S3 costs); approx. 10,000 baselines; effectively a custom full Percy-like implementation
• REST API and GraphQL testing
• Python Scrapy – website crawling (dead link testing)
• DynamoDB, ExpressJS, React – implementation of an application for managing visual tests, comparing test results, and approving changes after release
• Ability to compare results across environments (current production vs. last release production or test environment)
• Application also stores links to all reports and supports searching reports by:
  Tested application versions
  Date
• Reduction of automated test execution time by 30%
• Implementation of token caching so that the entire CI test run is authorized; authorization is performed once every 6 hours in a separate pipeline, with tokens stored on AWS S3
• Implementation of Slack bots to streamline the testing process; bots are connected to a dedicated channel, provide full visibility, and can report test results directly to specific users via direct messages
• JavaScript Chrome extension for efficient work with Allure reports, enabling copying of ready-to-use CLI commands that can be executed on CI or locally
• Working simultaneously in two international teams
• Automatic E2E tests documentation using LLM
• Improving processes by creating custom applications supporting release process
• Using AI to verify failed tests and fix it if possible
• Developed custom test automation libraries, enabling easier scripting and increased reusability across projects

Implementation and maintenance of automated tests:

• Implementation and long-term maintenance of automated test suites using Java & Selenium as well as Groovy & SuperBot, covering functional, regression, and end-to-end scenarios
• Designing and executing API tests in Postman, including validation of business logic, data consistency, and integration between services
• Preparation of migration scripts and automated tests in Ruby, supporting data migrations and ensuring correctness and stability after system changes
• Close collaboration with developers, QA engineers, and product owners to analyze requirements, identify test scenarios, and improve overall test coverage
• Active participation in international, distributed teams, working across different time zones and cultures while maintaining effective communication and delivery standards

Manual and automated testing:

• Manual testing using Fiddler and Proxyman for HTTP/HTTPS traffic inspection, request/response analysis, and debugging of client–server communication
• Creation and maintenance of test documentation, including test cases, test plans, and test scenarios to ensure clarity and repeatability of the testing process
• Automated API testing with Postman, including building and maintaining comprehensive API documentation and running automated collections using Newman in CI environments
• Implementation of automated UI tests using Selenium with .NET as well as Cypress with JavaScript, covering critical user flows, regression scenarios, and cross-browser validation
