Start Building Your Skillset With My One-to-One Courses
Hi, my name is Jacek and I love spreadsheets! Whether you’re hoping to improve your spreadsheet skills and master spreadsheet programs — such as Microsoft Excel and Google Sheets — or you’re looking to take control of your data by developing your data analytics and financial modelling skills, I have just the courses for you.
Using my experience from over 10 years in Commercial Finance and Data Analysis, and my passion for data, I’ve created Excel and data analytics online courses for people of all abilities.
Why Choose My Courses?
One-to-One Lessons for Personalised Support
All of my courses are one-to-one. This means the lessons are tailored to your specific needs, taking into account your previous experience, with the pace of the course adjusted to suit your pace of learning.
Benefit from Hands-On Learning
To help you build your confidence in working with data, I include hands-on learning activities in my courses. You can apply lessons learned to spreadsheets or financial models with me on-hand to offer assistance and guidance.
Learn to Love Data
For many people, working with spreadsheets and making sense of data can feel like a chore. But believe it or not, I’m passionate about data and it’s potential. So my goal is not just to help you learn how to create spreadsheets and make the most of data — I aim to help you enjoy organising, analysing and presenting data.
One-to-One Crash Course
This intensive private lesson is perfect if you need to get your Excel skills up to scratch before starting a new job, attending an interview or sitting an exam. We can start from the basics if you are a complete beginner or work to refresh your existing knowledge of Excel and tackle more advanced Excel functions.
Data Analytics Course
Python is a widely-used programming language that has become an essential data analysis tool — and the good news is, it’s relatively easy to learn. Whether you’re new to data analysis or programming in Python, this course can help you learn everything you need to know.

If you want to start or grow your business, this comprehensive course is perfect for you. You’ll learn to build a financial model, create accurate cash flow forecasts in Excel including how to calculate the return on investment or conduct a sensitivity analysis.
