Data Scientist skilled in analytics, dashboards, and automation—turning complex data into executive-ready business insights.
What I'm looking for
I’m a data-focused professional with strong analytical problem-solving, statistical thinking, and structured decision-making. I specialize in business reporting, dashboard development, data validation, and operational analytics, translating findings into clear, practical insight for real business decisions.
At IBOSS, I collect data from web sources using Python, clean messy datasets with Pandas, and improve data quality to support more reliable analysis. I analyze business performance to identify trends and gaps, and I build executive-ready dashboards and reports using Power BI and Excel—reducing reporting time by 30%.
Previously as an Operations & Data Assistant at Gifthouse Ventures, I handled high-volume data processing with 99% accuracy to ensure reliable record-keeping and operational continuity. I produced monthly performance reports with advanced Excel functions, improving reporting efficiency by 25%, and strengthened documentation systems to reduce retrieval time by 40%.
I’m driven by clarity and sound judgment—especially when technical work must directly support decision-making. With ongoing Data Science training (including a Google Data Analytics Professional Certificate and Coursera programs), I bring dependable execution, critical thinking, and meticulous attention to detail to every project.
