I am a Production Support Engineer with over 4 years of hands-on experience supporting enterprise healthcare analytics and Big Data platforms in 24×7 SLA-driven environments.

I specialize in SQL, Hive, ETL monitoring (Apache Airflow), Linux log analysis, and real-time incident management. Throughout my career, I have worked extensively on data validation, root cause analysis (RCA), SLA monitoring, and production stability improvement. I also have experience in automating monitoring processes using Python to reduce repeat failures and improve system performance.

As a trainer, I focus on practical, job-oriented learning rather than only theoretical concepts. My sessions include:

• Real-time SQL scenarios used in production
• Interview-focused query practice
• Hands-on assignments with datasets
• Production support case studies
• Resume and interview guidance

My goal is to help students gain confidence, clear SQL interviews, and understand how SQL is used in real IT production environments.

If you are a beginner, fresher, or working professional looking to strengthen your SQL skills with real-time examples, I am here to guide you step-by-step.
