    As a Junior Backend Developer at Optare, my primary responsibilities involved managing the incident lifecycle. I analyzed incoming incidents and error reports to diagnose issues, identify potential solutions, and escalate tickets to the appropriate team. When an issue fell within my team's scope, I was responsible for developing and documenting the required code fix. Following development, I submitted the solution to the testing (QA) team for validation before it was deployed to the production environment."
