Oluwatobi Titilayo

I’m a Certified DataAnalyst and DataAnalytics Trainer focused on turning raw datasets into actionable insights. I use SQL, Excel, Power BI, and Python to support data cleaning, statistical analysis, and visualization for both business and academic decision-making.

In my current role as a DataAnalysis Trainer, I deliver structured training in Excel, SQL, Power BI, and Python. I create industry-relevant projects, mentor trainees on job-ready portfolios, and track progress through assignments and performance evaluations.

Previously, as a DataAnalyst & ICT Instructor, I led the management and maintenance of a Polytechnic’s central SQL database to ensure data accuracy, security, and availability. I analyzed and processed large datasets to generate reports for departmental planning, and I designed efficient data workflows using SQL, Excel, and Python.

I also teach TVET and Computer Science students practical applications of Excel, Python, and SQL, and I develop learning materials and hands-on projects that bridge theory with real-world analytics. I work closely with faculty and the ICT team to integrate analytics tools into student learning and institutional systems.
