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.
