About Esha

I am a Data Professional and Corporate Trainer specializing in SQL training, data analytics, and practical, industry-oriented learning. My approach combines real-world problem-solving with structured instruction to help learners develop strong SQL skills for professional and technical interviews.

With hands-on expertise in SQL queries, joins, Common Table Expressions (CTEs), window functions, subqueries, aggregations, and data analysis, I focus on teaching SQL as it is used in real business environments.

My training emphasizes practical exercises, real-world datasets, business scenarios, and query optimization techniques rather than memorizing syntax. Whether you are a beginner learning SQL from scratch, a working professional upgrading your data skills, or a candidate preparing for Data Analyst and SQL Developer interviews, my goal is to help you write efficient queries and solve problems confidently.
