Worked on the BloopAI/vibe-kanban repository to deliver a configurable Email Template IDs feature for Loops, enabling self-hosted deployments to override default invite and review notification templates through environment variables. This solution was implemented using Rust for backend logic and Docker for deployment, with supporting changes in YAML configuration files. The approach allows runtime customization of email templates, reducing the need for manual patching and improving maintainability for self-hosted users. Documentation, including deployment and local development guides, was updated to reflect these changes, ensuring that users can easily adopt the new configuration options in their own environments. No bugs were addressed.
