ABOUT KEILA BANZA
Hello and Welcome I am an Emerging Data Science and Analytics Lead dedicated to transforming complex data into meaningful insights that drive strategic decisions and elevate client experiences. My work sits at the intersection of Machine Learning/AI, analytics, project management and business strategy, where I design scalable data systems, lead analytical initiatives and translate data into clear, actionable narratives.Currently, I work at ATB Financial as part of the Client Intelligence Analytics team, where I have built and deployed foundational data assets that power client experience reporting across the organization. My experience spans the full data science lifecycle — from structuring BigQuery datasets to conducting advanced statistical analyses in Python and developing interactive dashboards and presentations that bring insights to life. I take pride in creating visually aesthetic and effective data stories, self-serve analytics tools and documentation frameworks that make data more accessible, reproducible and transparent across teams.Beyond technical execution, I am passionate about collaboration and enablement — partnering with business, product, and enablement teams to align analytics with strategic objectives. I approach every project with curiosity, empathy and a deep respect for the iterative nature of data-driven problem-solving.Before joining ATB, I gained experience as a Data Management Intern at SiMPACT Strategy Group and as a Research Assistant at the University of Calgary, where I contributed to a healthcare-focused machine learning project exploring predictive modeling in patient outcomes.I am continuously exploring how data science, mental health, and human-centered design can intersect to create technology that supports well-being and empowers people. My mission is to bridge data and human insight — helping organizations make smarter, more empathetic and evidence-based decisions.
