About Me
Hi, I'm Irene — a data professional based in Nairobi, Kenya with over five years of experience transforming complex datasets into clear, actionable strategies for businesses across industries.
I specialise in data analytics, statistical modelling, and interactive dashboards using tools like Power BI, Tableau, Excel, and Python. Whether you're trying to make sense of your numbers or need a reliable professional to keep your operations running smoothly, I'm here to help.
Beyond data, I also offer professional virtual assistant services — from managing emails and calendars to research, data entry, and project coordination — giving you reliable remote support so you can focus on growing your business.
When I'm not wrangling data, I create educational content on my blog, sharing practical tutorials and demos that make data analysis more accessible to everyone.
