Purushottam Kumar

Data strategy architect with 4+ years delivering measurable business impact across multi-country retail operations — including an audited 8.2x ROI on loyalty programme strategy and 70% compute cost reduction through advanced data engineering. I bridge the gap between C-suite strategy and production-grade technical systems. My work spans predictive churn modelling, enterprise RAG pipelines, customer segmentation engines serving 10M+ users, and fraud detection systems preventing $400K+ in annual revenue leakage. Technical stack: Python, PySpark, SQL, LangChain/LangGraph, Power BI, Tableau, cloud architecture, and MLOps. Currently expanding expertise in Generative AI through an Executive Certificate programme from IIT Patna. MBA from Swansea University (UK) with specialization in Sustainability & Innovation, combined with a Post Graduate Diploma in Data Science from IIIT Bangalore. This unique fusion enables me to translate complex data initiatives into boardroom-ready strategy and vice versa. Proven leadership: built and directed a 6-analyst team across 3 geographic markets, achieving 100% on-time delivery over 24 months. Seeking remote opportunities in data strategy, AI architecture, analytics consulting, or data engineering roles where I can drive transformative business outcomes.
