Data analytics instructor and analyst helping teams turn SQL and dashboards into data-driven decisions.

What I'm looking for

I’m looking for roles where I can turn data into decisions—building dashboards and ETL workflows—while mentoring others. I want to grow into Data Science through applied analytics and real-world problem solving.

I’m a data analytics instructor and data analyst with over 10 years applying data-driven approaches to solve business problems and deliver technical training. I’m proficient in SQL, Python, Power BI, and Tableau, with a strong focus on analysis, visualization, and teaching.

In my current role as a Data Analytics Instructor (Findworka, April 2024–present), I deliver structured training to 100+ learners using SQL, Excel, and Power BI. I develop hands-on projects that mirror real-world scenarios and mentor students into entry-level data roles.

Previously, I served as a Data Analyst & Instructor at Oghas Technology (December 2019–January 2024), where I designed and maintained ETL pipelines and trained over 200 learners in SQL, Python, Power BI, and Excel. I also built dashboards to support business decision-making.

Earlier, as Head of IT / Data Lead at Proshare Nigeria (September 2010–September 2020), I led IT and analytics operations, improved performance by 15%, and ensured 98% data accuracy through strong governance. I’m passionate about advancing into Data Science through postgraduate study and bringing analytical techniques to real-world challenges.
