Revathy Ramalingam is a Senior Software Engineer and AI Engineer at a healthcare startup. Her path into AI engineering was anything but linear: she spent over nine years building software in the telecom domain before stepping away from her career for seven years. Coming back to an industry that had kept moving was a challenge she met deliberately, retraining through DataTalks.Club’s ML Zoomcamp, the AI Dev Tools Zoomcamp, and the AI Hero email course, and rebuilding her skills step by step until she landed her current role.

Today she is an active member of the data community and a generous presence in course forums, helping other learners the way she once needed help herself. She speaks openly about the realities of restarting a tech career after a long break: how to prepare for AI engineering interviews, what hiring managers actually look for, and which study strategies made the difference. Her story is a practical playbook for anyone returning to tech after time away.
