I’m a Senior Data Engineer with hands-on experience building, optimizing, and troubleshooting large-scale data pipelines and data platforms. I work extensively with AWS, PySpark, Apache Spark, Airflow, EMR, S3, Glue, Athena, Hive, and Apache Iceberg, solving real-world data engineering challenges around performance, scalability, pipeline design, orchestration, and data processing. Through Topmate, I’d like to help aspiring and working Data Engineers with: * Data Engineering career guidance and learning roadmaps * PySpark, Spark and SQL * Spark performance optimization and debugging * AWS Data Engineering * Airflow and data pipeline orchestration * Apache Iceberg and modern data lake architectures * Data Engineering interview preparation * Real-world project and technical problem-solving My sessions are focused on practical, real-world Data Engineering rather than just theory. Whether you’re trying to enter Data Engineering, prepare for an interview, improve your technical skills, or you’re stuck on a Data Engineering problem at work, feel free to book a session and let’s work through it together.
