Ellen Sebiano

I am a detail-oriented Data Analytics graduate with hands-on experience in data management, system analysis, and data visualization. I specialize in transforming raw and unstructured data into meaningful insights that support better decision-making and operational efficiency.

I have experience working as a System Data Analyst and Quality Analyst at Baguio City Hall, where I reviewed and evaluated data practices across multiple offices. I provided feedback on how departments structure, store, and manage their Excel-based datasets to improve consistency, accuracy, and usability. I also cleaned and standardized collected data, then developed interactive reports and dashboards using Looker Studio to support monitoring and reporting needs.

My work includes selecting and mapping the most appropriate data visualizations to ensure clarity, usability, and impact for stakeholders. I focus on presenting data in a way that is both visually effective and easy to understand.

I am proficient in Excel, Google Sheets, SQL, Python, and Looker Studio, with strong attention to detail and a commitment to high-quality outputs. I am adaptable to remote work and dedicated to delivering accurate, organized, and insight-driven results on time.

I am eager to help clients improve their data processes, build effective dashboards, and turn complex data into clear, actionable insights.
