Meet Your Instructor
Hi, I'm Sachin
I’ve spent many years helping organisations across a range of industries build practical Excel and Business Intelligence solutions, analyse data and automate reporting. I created Data Mastery to help students not only develop the skills and confidence to use Excel effectively, but also to understand how everything fits together as a complete analysis and reporting workflow.
Why I created Data Mastery
I created Data Mastery to provide a structured learning experience that combines practical examples, real-world datasets and hands-on exercises, helping students build confidence and apply practical Excel and Business Intelligence skills in their own work.
Courses are designed to be modular, allowing students to either follow the complete learning pathway or jump directly to the topics most relevant to their experience and goals.
Professional Experience
Excel Expertise
Over two decades of commercial experience building Excel solutions, from formulas and PivotTables through to advanced reporting and automation across industry.
Power BI
Designing interactive dashboards, building semantic models, writing DAX measures and creating business intelligence solutions for professional reporting.
SQL Developer
Extracting, transforming and analysing business data using SQL across relational databases to support reporting and decision making.
Business Intelligence
Designing end-to-end reporting solutions that transform raw data into meaningful insights for business decision-making.
What Makes Data Mastery Different?
Structured Learning
Follow a carefully designed learning pathway that builds knowledge step by step, while giving experienced learners the flexibility to jump directly to the topics most relevant to them.
The Complete Process
Learn how importing, preparing, analysing, visualising and reporting data fit together as one complete workflow rather than a collection of individual features.
Practical Business Focus
Develop practical skills and techniques that can be applied confidently to reporting, analysis and Business Intelligence tasks in professional environments.
Learn at your own Pace
Study at a pace that suits you, revisiting topics whenever you need and learning on your own schedule without time restrictions.
Looking Ahead
Data Mastery is more than a single Excel course. It represents a long-term vision to help students develop practical data, analytical and reporting skills through structured, real-world learning experiences.
This Excel course is the first step in that journey. Future courses, including Power BI and other Business Intelligence topics, will continue to build on the same practical teaching philosophy.
My goal is simple: to continue creating high-quality learning resources that help students build confidence, develop valuable skills and solve real business problems with data.
