I worked as a member of the QA team at GoMore Company from January to December 2022. In addition to algorithm validation, my responsibilities included collecting human and motion data (such as PPG/ACC/Heart Rate or Speed) and collaborating with the company's DevOps and RD teams. Together, we completed the implementation of automated internal testing processes, enhancing the overall CI/CD system and improving internal efficiency. I also took charge of designing and refactoring the QA testing framework to achieve better modularity of test items. I led code reviews within the team and served as a mentor for three new colleagues. Communication was highly valued, and I emphasized effective collaboration among team members. During this role, I utilized various tools such as pytest, Git, Docker, and Jira. These tools supported our testing efforts, version control, and task management, contributing to increased efficiency and collaboration. In 2023, I transitioned to the SA team within the company, embarking on new professional challenges.
