About

 

I am Tolu Olabiyi, a Data Analyst with over five years of experience helping organizations turn complex datasets into clear insights that drive growth and innovation. My work spans across finance, healthcare, and research, where I have delivered impactful solutions such as improving credit approval accuracy, detecting fraud, and building predictive models that enhance decision-making.

I am proficient in SQL, Python, Power BI, and Excel, with strong skills in automation, dashboarding, and data-driven storytelling. Over the years, I have also developed a passion for using data to solve real-world problems, from optimising mobile banking apps to designing machine learning models that reduce customer churn.

Beyond technical expertise, I value collaboration, clarity, and continuous learning, which enable me to bridge the gap between raw data and business strategy. My goal is simple: to empower individuals and organisations to make smarter, faster, and more confident decisions through data.

My Data Philosophy

I believe data is more than numbers—it’s a tool for understanding people, solving problems, and driving smarter decisions. My approach goes beyond reports and dashboards; it’s about uncovering insights that create meaningful impact for businesses and their customers.

Turning Data Into Purposeful Insights

Every dataset has a story. I specialise in transforming raw information into clear, actionable strategies that improve performance, reduce risks, and unlock opportunities.

User-Centric Analysis

Whether it’s optimizing customer experiences or improving financial systems, I always put the end user at the heart of my analysis to ensure solutions are practical and effective.

Innovation and Adaptability

With expertise in SQL, Python, Power BI, and predictive modelling, I embrace new tools and methods to solve evolving business challenges.

Collaboration and Communication

Great insights only matter if they are understood. I focus on making complex findings simple, ensuring stakeholders at every level can act on data with confidence.
