Olalekan A.

I help businesses turn raw, messy data into clear dashboards and reports that support real decisions, and I build AI driven content systems that produce visuals, video, and training material at scale. My work covers two areas clients increasingly need from one professional. On the analytics side, I clean, validate, model, and visualise data using Excel, SQL, Power BI, Python, and Power Query to uncover trends, improve data quality, automate reporting, and provide actionable business insights. On the content side, I design AI powered workflows that generate marketing creatives, social media content, product visuals, educational content, and training materials using ChatGPT, Midjourney, Runway, Kling, Sora, CapCut, and other Generative AI tools. I am a Microsoft Certified Trainer with expertise in Microsoft 365, Power BI, Azure, Data Analytics, Business Intelligence, and Digital Transformation. I also completed a Data Science and Big Data Analytics programme covering Python, SQL, Machine Learning, Statistical Analysis, and Data Modelling. With more than 15 years of experience across education, government, technology, and business transformation projects, I have helped organisations improve reporting, automate manual processes, strengthen decision making, and scale content production.
