Hi, I'm Aakash 👋 I'm a Senior Data Engineer with 5+ years of experience designing and building scalable data platforms on Snowflake and AWS. Throughout my career, I've worked on modern data stack technologies including Snowflake, dbt, Apache Airflow (MWAA), AWS Glue, PySpark, SQL, and cloud-based ETL pipelines. I've been involved in migrating legacy on-premises data platforms to Snowflake, building production-grade data pipelines, optimizing warehouse performance, implementing medallion architectures, and solving real-world data engineering challenges at scale. I enjoy mentoring aspiring and experienced data engineers by simplifying complex concepts into practical, interview-ready knowledge. I can help you with: - Snowflake (Architecture, Performance Tuning, Streams & Tasks, Security, Snowpark) - dbt (Models, Incremental Loads, Testing, Best Practices) - PySpark & SQL Interview Preparation - Airflow & AWS Glue - ETL Pipeline Design & Data Warehousing - Data Engineering System Design - Resume Reviews for Data Engineers - Mock Interviews (SQL, Snowflake, PySpark, dbt) - Career guidance for transitioning into Data Engineering Whether you're preparing for interviews, stuck on a technical problem, or looking to grow as a Data Engineer, I'd be happy to help.
