About Sayen

Hi, I’m Sayen, a Database Developer with hands-on experience in SQL Server/MySQL/Oracle, Data Warehousing, and ETL. I help students and working professionals master SQL from basics to advanced concepts with practical, real-world examples.

I teach:

• SQL (Beginner to Advanced)
• Joins, Subqueries, CTEs, Window Functions
• Stored Procedures (Oracle / SQL Server / MySQL)
• PL/SQL (Cursors, Exceptions, Packages)
• Query Optimization & Performance Tuning
• Data Warehouse & ETL fundamentals
• Interview Preparation (Scenario-based questions)

My teaching style is simple, structured, and practical. I focus on building strong fundamentals and then move to advanced concepts used in real projects. Whether you are preparing for interviews, switching careers into data, or struggling with assignments, I can guide you step by step.

About the lesson

My classes focus on practical, hands-on learning of SQL Server/MySQL/Oracle with real-world project examples. I cover fundamentals to advanced concepts, including query writing, performance tuning, and stored procedures. Sessions are interactive, personalized, and strongly focused on interview preparation, problem-solving, and building real industry-level confidence.
