Worked on the teslamate-org/teslamate repository to enhance deployment compatibility behind OAuth2 Proxy by addressing header value length limitations. Focused on backend development using Elixir, the work involved increasing the maximum header value length to prevent truncation and ensure reliable authentication flows when TeslaMate is used with OAuth2 Proxy. Additionally, improved the clarity and maintainability of configuration files, specifically config/runtime.exs, to streamline future updates. The targeted bug fix resolved issues with header handling, supporting smoother integration with authentication proxies. This contribution demonstrated attention to configuration management and backend reliability, emphasizing robust Elixir practices for secure and maintainable deployments.
