About me

Hi, I’m Barbara Mackey, data analyst, instructor, and creator of LookerCourses.com. I help people and teams turn data into clarity, confidence, and better decisions.

With more than 20 years of experience in the digital industry, I’ve worked with incredible brands like Net-A-Porter, Zara, Mango, and Black&Decker. Over the years, I’ve implemented analytics tools in more than 100 websites and helped companies of all sizes build dashboards, measure performance, and grow through the power of data.

💡 My story

I started my career in marketing, where I quickly realised how powerful data could be when it was understood and shared clearly. That curiosity led me into the world of digital analytics, and I never looked back.

After leading analytics projects for agencies and global brands, I founded MKwise.net, where I help businesses become more information-driven through web analytics, dashboards, and data training. I’ve since written a book about Looker Studio and created several online courses to make learning analytics simple and accessible for everyone.

Today, through LookerCourses.com, I share practical tutorials, resources, and step-by-step guides to help professionals and teams make sense of their data. Without feeling overwhelmed by it.

✨ What sets me apart

  • ✔ I’m a good listener and a natural problem solver. I love helping people find clarity in complex data.
  • ✔ I’ve implemented analytics tools in 100+ websites over the last two decades.
  • ✔ I bridge data and marketing. My marketing background helps me translate insights into real business impact.
  • ✔ I believe in quality and efficiency. I deliver high-standard work, fast.
  • ✔ I genuinely love teaching and seeing others grow their confidence with data.

📚 My courses & training

I teach Looker Studio, Google Analytics 4, and AI-powered tools like Gemini and NotebookLM through practical, beginner-friendly courses. My goal is to help you not just learn, but truly apply what you learn to your own projects.

🚀 Professional Background

Before creating LookerCourses.com, I worked as a Data & Analytics Lead at several agencies and technology companies, leading projects for international clients across e-commerce, travel, and finance. Some highlights:

  • 📊 Led analytics projects at Net-A-Porter, where I analysed customer behaviour and built dashboards used across global teams.
  • 💻 Created performance dashboards for over 60 websites at Hugo & Cat, including brands like Black+Decker and DEWALT.
  • 🧠 Founded the Insights team at Empathy.co to develop data products and visualisation tools for retailers.
  • 📈 Delivered data strategy and optimisation projects at TIYO, Kantan, and multiple agencies in London and Madrid.

Throughout my career, I’ve combined data analysis, marketing insight, and storytelling to help businesses make better, faster, more informed decisions.

🌍 Beyond Analytics

I live in London (a city I genuinely love) and when I’m not working on dashboards or writing tutorials, you’ll probably find me going for long walks, cycling, or spending time with my family.

That balance between creativity and everyday life is what inspires me most. It even led me to create Fun and Play, a local website for families, where I share ideas for activities and places to explore together.

Whether I’m working on data or family projects, I’m always drawn to building things that help people connect, understand, and enjoy what they do a little more.
