I am a Data Engineer focused on building scalable, production-ready data pipelines using PySpark, SQL, Snowflake, and modern DataOps practices. My work goes beyond writing queries — I design end-to-end data architectures, implement CI/CD pipelines using GitHub Actions, apply testing and linting standards, and build structured Bronze–Silver–Gold data layers with proper error handling and audit controls. I specialize in: PySpark transformations and performance optimization Data modeling and warehouse design (Snowflake) CI/CD for data pipelines ETL framework design with logging and monitoring Real-world project architecture and interview preparation If you're transitioning into Data Engineering or want to move from “tutorial knowledge” to production-level implementation, I can help you think like an engineer — not just a coder.
