About Uttam Kumar
have spent 18+ years at the intersection of mobile payments, data engineering, and AI — building and scaling systems that directly impact how millions of people access financial services across Africa and beyond.I lead technical programmes at my current organisation for Payment Domain — one of Africa\'s largest mobile wallet platforms, serving 90 million subscribers. My work spans three areas:**Generative AI Delivery**I built WalletMind AI — an on-premise GenAI chatbot for Orange Money customer support using Ollama (Llama 3), LangChain, and ChromaDB. It runs fully locally — zero cloud cost, PCI-DSS compliant — and cut average support resolution time from 12 minutes to 4 minutes. No financial data leaves the network. No monthly API bill.**Data Engineering**I architected FabricLedger — a production Microsoft Fabric OneLake Medallion Lakehouse (Bronze → Silver → Gold) consolidating 12+ Orange Money data sources. It processes 10M+ daily transactions, reduced settlement reporting from T+1 to 15 minutes, and cut pipeline costs by 70%.**Technical Programme Management**I lead multi-ART SAFe delivery across 50+ engineers — PI Planning, OKR-based tracking, flow metrics — maintaining a 92% on-time delivery rate across complex, multi-country programmes.Earlier in my career I built the VISA payment integration for Orange Money (AfricaCom Best Mobile Money Award 2013) and designed a Smart City Big Data platform on Hadoop, NiFi, and Apache Spark.What I\'m looking for:Senior roles as Technical Program Manager, Technical Product Manager, Engineering Director, or Enterprise Architect — in Fintech, Mobile Money, Payments, or Data Engineering where I can apply 18 years of domain depth at greater scale.Email: u••••••••@gmail.com
