Cliff Otieno

I am a highly motivated and detail-oriented Data Analyst with a solid foundation in data exploration, visualization, and reporting. Over the past few years, I have developed and refined my skills in Excel, Power BI, and RStudio, which I have used extensively to manipulate data, uncover trends, and deliver actionable insights. My experience includes transforming raw data into interactive dashboards, automated reports, and visual narratives that aid decision-makers in understanding complex datasets with clarity and precision.

Excel has been a core tool in my day-to-day work, from advanced functions and pivot tables to complex formulas and data modeling. In Power BI, I have created custom dashboards that not only display key performance indicators but also enable end-users to filter and interact with the data, providing flexibility and deeper insights. My proficiency in RStudio has allowed me to conduct statistical analyses and predictive modeling with confidence, leveraging packages like dplyr, ggplot2, and tidyverse to clean data, visualize relationships, and interpret results.

In addition to my technical capabilities, I have strong communication skills developed through academic writing and professional report development. I have authored data-driven research papers, evaluation reports, and executive summaries that communicate findings clearly and concisely to diverse audiences, including non-technical stakeholders. My academic writing background has also given me a critical approach to problem-solving, evidence-based analysis, and logical structure—skills that I bring into every project.

I thrive in collaborative environments where continuous learning and improvement are valued. I enjoy working with cross-functional teams, understanding their goals, and translating those into data requirements and analytical outputs. My approach is proactive and results-oriented, and I take pride in ensuring that the insights I provide lead to practical improvements and informed decisions.

Whether it's identifying performance gaps, visualizing business trends, or helping organizations make data-driven choices, I bring a commitment to accuracy, clarity, and meaningful analysis. I am currently seeking a role where I can continue to grow as a data professional, contribute to impactful projects, and help organizations harness the power of data for measurable success.
