Swagatika Banerjee contributed to the kestra-io/plugin-azure and kestra-io/kestra repositories by delivering targeted improvements in logging, onboarding, and localization over a two-month period. She refactored Azure plugin classes in Java to replace @Slf4j annotations with manually instantiated loggers, enhancing logging consistency and maintainability while reducing external dependencies. In the core Kestra app, she improved the onboarding experience by updating the welcome page and streamlined localization in Vue.js components by standardizing translation methods. Her work focused on maintainable code, UX clarity, and collaborative development, demonstrating depth in software refactoring, front end development, and documentation using Java, JavaScript, and Vue.
