Luciano Casillas

I specialize in transforming complex datasets into actionable operational solutions that drive performance, staffing efficiency, and customer experience. With over 10 years of experience across telecommunications, insurance, and healthcare, I bridge the gap between advanced data science and executive-level strategy. Leadership & Talent Development Beyond technical execution, I am passionate about developing analytical talent. I have a proven track record of mentoring analysts through a structured "graduated responsibility" model—coaching them to move past "data dumping" toward high-impact data storytelling. I specialize in building team-wide QA frameworks that ensure data validation, SQL optimization, and visualization standards meet the rigorous demands of executive leadership. Strategic Data Partnership My work connects data with people. I partner with Call Center Directors and Executive VPs to translate ambiguous business challenges into structured analytical roadmaps. Whether I am refining capacity models to improve predictive accuracy by 20% or building Tableau/Power BI ecosystems that improve operational efficiency by 15%, my focus is always on the "why" behind the metrics. Technical Expertise & Domain Knowledge I combine deep technical proficiency in SQL (Snowflake, MySQL), Tableau, Power BI, and Python with a background in workforce optimization and service operations. Having worked in auto insurance, health insurance, and telecom, I bring a broad perspective on retention dynamics, staffing forecasts, and KPI standardization. Currently, I am completing my B.S. in Data Science at WGU, expanding my expertise in machine learning and predictive modeling to solve the next generation of business challenges through automation and data-driven storytelling.
