Top SchoolBill Zichos is a Chief Architect and Cloud Data Scientist with 11 years of experience designing and delivering data products—from ETL pipelines and dimensional models to web services and predictive algorithms—for public and private sector clients. Based in Severna Park, MD, he leads data science teams at Index Analytics, turning research into production-quality services (NLP, recommender systems, causal impact analysis) that measurably inform product decisions for federal digital services and healthcare systems. His background spans BI architecture, report automation, and feature engineering—evidenced by a history of shipping hundreds of reports, building enterprise data warehouses, and productionizing models with Git-based workflows and CI/CD. He champions a culture of experimentation and engineering rigor: unit tests, peer review, trunk-based branching, and two-week sprints are standard practice in his teams. Notably, he translated customer language insights into language models that power autocomplete, spelling correction and the foundations of an information retrieval system for Medicare-focused services.
