Aspiring data analyst using financial-service insights to drive better decisions.
NigeriaWhat I'm looking for
I’m an aspiring Data Analyst with 12+ years of experience in the financial services sector, specializing in customer insights, dispute resolution, and process improvement. I’m recognized for leveraging data to solve problems, optimize workflows, and support decision-making.
Recently, I upskilled in Excel—pivot tables, charts, conditional formatting, What-If analysis, data cleaning, and dashboards—so I can turn raw information into clear, actionable reporting. Through my learning portfolio, I built a Household Budget Dashboard and completed Customer Transactions Analysis and Savings Forecasting to understand trends and test scenarios.
In my roles at Access Bank Plc, I analyzed 50+ daily customer queries, reduced dispute resolution time by 30%, and improved client retention by 15% through proactive engagement insights. I’m now seeking an internship/entry-level data analysis role to apply these analytical skills and grow expertise in business intelligence.
