Brian Wanjiku - Data Scientist & Full Stack Developer

About Me

Data Scientist & Full-Stack Developer

I'm a professional statistician and data scientist with deep expertise in statistical analysis, machine learning, and predictive modeling. I bridge the gap between complex data insights and practical web solutions by building full-stack applications that make data accessible and actionable.

My unique combination of statistical rigor and software development skills allows me to create end-to-end data solutions - from exploratory data analysis and hypothesis testing to deploying ML models in production-ready web applications using modern frameworks like Django, React, and cloud platforms.

Whether it's performing complex statistical modeling in R and Python, building interactive data dashboards, or developing AI-powered analytics platforms, I transform raw data into meaningful business intelligence through both rigorous analysis and intuitive user interfaces.
