Data Analyst | SQL, Excel, Power BI | Turning data into clear, actionable business insights
What I'm looking for
I'm Oluwatobi Ishmael, a data-driven professional transitioning from a background in internal audit into the exciting world of data analytics and cloud computing. My career began in auditing, where I developed a keen eye for detail, risk assessment, and process optimization. Over time, I realized my passion for working with data went beyond compliance—I was drawn to uncovering patterns, solving business problems, and making data-driven decisions.
To make this shift, I upskilled in key data analytics tools and technologies. I now have hands-on experience in:
SQL (PostgreSQL) – Writing complex queries for data exploration and cleaning
Microsoft Excel – Using pivot tables, charts, and formulas to build dynamic dashboards
Power BI – Creating interactive visualizations and reports for business users
Data storytelling – Summarizing insights into clear, actionable takeaways
Cloud computing fundamentals (AWS) – Currently building foundational knowledge to support scalable data solutions
I've applied these skills through real-world projects such as analyzing bike sales data, automating Excel-based audit reports, and building Power BI dashboards to track performance metrics. My audit background gives me a strong business mindset—I focus not just on what the data says, but why it matters to stakeholders.
My interests lie in:
Helping businesses make sense of their data
Supporting decision-making with clear analytics
Exploring cloud-based data solutions and automation
Creating educational content to share what I’m learning in public
I’m actively seeking opportunities—full-time or freelance—where I can contribute to data teams, build my skills, and work on impactful projects. I'm especially excited by roles that value growth, autonomy, and collaboration.
Let’s connect if you're building something data-driven!
