Summary
👤
Senior🎓
Top SchoolRobert John is a Managing Director and Google Cloud Certified Professional Data Engineer with 8 years of experience transforming software engineering foundations into production-ready data platforms and ML pipelines. Based in Lagos, he has led data teams and architecture at fintech and SaaS companies, built terabyte-scale warehouses, and optimized cloud migrations and containerized workloads for reliability and cost. He combines hands-on model development—recently training NLP sentiment models on Nigerian tweets and news—with strategic ecosystem building, now driving ChipMango’s continent-wide microelectronics training and partnerships. An active contributor to data-science learning projects on GitHub, his notebooks for PacktWorkshops demonstrate practical exercises in feature engineering and model building. Known for bridging technical delivery and external engagement, he mentors multidisciplinary teams and tailors learning content for regional impact. His background in mathematics and a Udacity nanodegree in data visualization underpin a pragmatic, data-driven approach to storytelling and productization.
