Hi, I'm Teresia Mwangi, a data analyst with a curiosity grounded in real-world operations. I love uncovering patterns and insights hidden within data, specializing in SQL, Power BI, Excel, Python and the full analysis lifecycle to turn raw information into clear, actionable intelligence.
I believe in the power of curiosity, integrity, and human-centered insights.
I don't just analyze data; I understand where it comes from—and the people it serves.
My journey began not behind a screen, but on the ground in procurement and warehouse management. While managing inventory and coordinating with teams, I learned that every data point represents a real decision, a bottleneck avoided, or an opportunity seized. This hands-on experience taught me to ask better questions and to never lose sight of the human impact behind the numbers.
With a background in Economics and Finance, I naturally gravitate toward insights that matter—those that drive ROI, unlock efficiency, or illuminate hidden patterns. But what truly drives me is curiosity: the desire to understand why things work the way they do, and how we can make them better.
Outside of work, I'm a lifelong learner who enjoys exploring new cultures, staying active, and finding creative ways to solve everyday problems. Whether I'm collaborating with a team or diving deep into a dataset, I bring the same values: integrity, empathy, and a commitment to continuous growth.
The principles that guide my work and life
I approach every problem with genuine curiosity, always asking "why?" and "what if?" to uncover deeper insights.
I believe in honest communication, ethical data practices, and building trust through consistent, reliable work.
I'm committed to learning, adapting, and evolving—whether mastering new tools or understanding diverse perspectives.
