Alex Churin focused on front-end development for the MHSanaei/3x-ui repository, addressing a UI stability issue in the WireGuard modal for VPN settings. By analyzing the rendering logic, Alex identified and removed an unnecessary v-for directive from the tr-info-row component, which had caused unintended iterations and display bugs. This targeted fix, implemented using HTML and front-end engineering best practices, improved the correctness and reliability of the modal across different environments. The work was delivered as a single, well-scoped commit with clear traceability to the related issue, reflecting a methodical approach to bug resolution and UI maintenance within the project.
