About Supriya
I’m a Senior Business Analyst with 10+ years of professional experience in Business Analysis, Data Analytics, SQL, Excel, Power BI, and technology.
Throughout my career, I have worked with data to solve business problems, analyze trends, create meaningful insights, and support important business decisions. I enjoy simplifying complex concepts and helping others become confident with data and SQL.
As a tutor, my goal is to make learning practical, easy to understand, and relevant to your career goals. Whether you are a complete beginner, a student, a working professional, or preparing for a Data Analyst/Business Analyst interview, I will tailor the lessons to your learning needs.
I believe the best way to learn SQL is by practicing real-world problems rather than simply memorizing syntax. My lessons are interactive, hands-on, and focused on building skills you can actually use.
I look forward to helping you learn SQL, improve your problem-solving skills, and become confident working with data!
