• Apply data storytelling techniques to explain trends, patterns, risks, operational performance, and analytical findings in a manner that supports informed ICE/ERO management decisions.
• Write and optimize SQL queries to extract, join, aggregate, validate, and prepare data for Qlik applications, reporting, and analytical use.
• Use Python, R, SQL, Qlik, and other BI or visualization tools to analyze datasets, automate repeatable reporting, and support operational analytics.
• Collaborate with federal stakeholders, data owners, analysts, engineers, and program staff to gather reporting requirements, define data needs, validate results, and deliver usable analytical products.
• Support the documentation of data sources, business rules, data transformations, Qlik application logic, dashboard calculations, reporting processes, and data-quality findings.
• Identify data-quality issues, reporting inconsistencies, data gaps, and opportunities to improve analytical workflows, dashboard usability, and reporting timeliness.
• Support ad hoc analysis, executive briefings, recurring reporting, and special projects as required by the LESA SOA Unit.
