What I'm looking for

I seek a role that fosters innovation and collaboration, offering opportunities for professional growth.

I am a skilled Data Analyst with over 4 years of experience in data visualization, statistical analysis, and database management. My career has been centered around uncovering actionable insights to drive business decisions and improve operational efficiency. I have worked with global organizations like the World Meteorological Organization, Yiaga Africa/UNDP, and the World Bank, where I developed dashboards, cleaned and managed large datasets, and implemented data governance practices.

I am passionate about using tools like SQL, Tableau, Power BI, and Python to create compelling visualizations and streamline processes. Some of my key achievements include improving operational efficiency by 30% through automated data workflows, enhancing data accuracy and consistency by 20%, and creating dashboards that facilitated real-time monitoring and decision-making.

Beyond my technical expertise, I am driven by a desire to solve complex problems and collaborate with cross-functional teams. I am also constantly learning to stay updated with the latest trends in data analytics. For example, I recently pursued certifications in Tableau and Power BI, which have enhanced my ability to design interactive dashboards.

In addition to my professional skills, I enjoy exploring how data intersects with real-world challenges, from improving public health to optimizing business processes. My long-term goal is to work on impactful projects that leverage data to drive innovation and make meaningful contributions.

I thrive in remote and collaborative environments and look forward to opportunities that allow me to use my skills to solve challenges, grow professionally, and make a difference.
