Front-end Developer in Kraków, Poland

Initially, as a member of the platform team, I prepared the project infrastructure that would be ready to migrate step-by-step the old monolith store into micro front-end apps. When the infrastructure was done, I migrated the project page by page and was responsible for scaling the application in increased traffic, such as during summer sales. For one week each month, I was on call. I responded within ten minutes on every OpsGenie alert, investigated the problem, and discussed it with other affected teams as needed. I decided whether the fix needed immediate action or if a follow-up ticket could be created.

A web extension that can be integrated with any website (such as a customer service software). It was created for enterprise customers and was compatible with Chrome, Firefox, and Edge. As a front-end developer, I was responsible for collecting the requirements, planning the project, choosing technologies, and implementing all features. The biggest challenge in the project was to create a polyfill layer covering all the differences between browsers' APIs. If the extension was enabled for a page, keywords were searched and returned all articles with solutions from the knowledge system API.
