I maintained and supported a large codebase that was developed three years ago. Additionally, I contributed to the project by creating new tests using the Selenide framework. I refactored existing code using modern approaches from the TestNG framework. While the CRM project initially did not emphasize extensive API testing, I proactively wrote several tests utilizing REST Assured to enhance test coverage in that aspect. I regularly reviewed pull requests from other developers on Bitbucket, carefully examining the code changes, ensuring they met coding standards, and giving constructive feedback to improve the overall code quality. I actively communicated with the team on Slack to quickly address and resolve issues.
