I am a Data Engineer with 4.5+ years of industry experience, currently working at Adidas and previously at Wipro. I have built and managed production-grade data pipelines, worked with large datasets, and optimized end-to-end data workflows used by real businesses.

As a teacher, I focus on helping students truly understand data engineering and modern AI, not just memorize tools. I teach core concepts like Python, SQL, Spark, PySpark, ETL pipelines, Databricks, Airflow, and cloud-based data systems, and then connect these foundations to real industry use cases.

- In addition to data engineering, I actively work with modern AI systems, including:
AI Agents for workflow automation and decision support
RAG (Retrieval-Augmented Generation) for combining LLMs with structured data
MCP-based architectures to build reliable, modular AI solutions
This allows me to guide students toward future-ready Data + AI roles.

- My teaching approach
Explain concepts from basics to production level
Use practical examples and real project scenarios
Focus on problem-solving, clarity, and strong fundamentals
Share insights on career paths, interviews, and industry expectations

Whether you are a beginner, student, or working professional, my goal is to help you build clear understanding, confidence, and job-relevant skills through structured and practical learning.
