Adapt your resume

List these exact terms on your resume: Machine Learning, Data Science, Experimentation, Production Deployment, and Python. An applicant tracking system matches the wording, not the idea.
Attach one line of real, concrete experience to at least one of them — a tool named with nothing behind it rarely survives a human read.
Lead with what you built, trained or shipped — this role is judged on the AI system itself, not the tools around it.
