Worked on the tracer-client repository to enhance backend reliability by implementing URL-centric improvements for both production and development environments. Focused on updating application URL endpoints to align with a new app URL, the changes improved user access consistency and streamlined development workflows. Addressed connectivity issues by ensuring the development environment correctly targeted the staging server, reducing endpoint-related errors and supporting smoother onboarding. Utilized Rust for backend development, emphasizing API development and integration to manage environment parity. All modifications were tracked in version control, resulting in more reliable local development and clearer URL resolution for both users and developers working with tracer-client.
