Experience

1. Senior Data Analyst, Wireless Business Operations

   Comcast

   Jul 2024 — Present · Philadelphia, PA, US

   I analyzed large-scale Xfinity Mobile network datasets containing billions of records to deliver performance and usage insights for executive reporting and dashboards. I collaborated with product, operations, customer support, and business development teams to drive operational alignment and support data-driven decisions. Using SQL across Snowflake and Oracle, I transformed complex datasets into actionable insights, presenting them through Tableau dashboards and Excel reports. I translated ambiguous business questions into structured analytical projects and shared clear recommendations with directors and VPs. I also maintained the accuracy of daily Condor reporting by identifying data anomalies, investigating root causes, and working closely with engineering teams to implement corrections. Key Contributions: • Saved $1M in annual cost and decreased 50% in engineering workload by applying geospatial analysis to reassess CBRS provisioning coverage and refine the radius from 30 to 15 miles. • Developed as a trusted data resource for executive leadership, with stakeholders directly seeking analytical insights and data-driven clarification for strategic decision-making. • Deliver presentations at executive leadership meetings, translating complex datasets into strategic insights for senior decision-makers.
