About Shahbaaz Halim

I’m a Data Scientist with 6+ years in IT, focused on building production-grade ML and decision systems that reduce operational noise and protect revenue.At Tata Consultancy Services, I design and deliver end-to-end data science solutions, not just models. I’ve built an unsupervised anomaly detection system for electricity distribution networks, cutting false alerts by 60–70% and reducing investigation time by ~40% through explainable, categorized alerts. I’ve also delivered a churn prediction and retention targeting system achieving ~3× lift in the top 10% segment, helping protect £3–5M annually.Currently, I’m designing a GenAI (RAG-based) incident triage system to reduce incorrect incident creation and first-triage SLA.I care about explainability, business alignment, and systems that work in production.
