Hi, I’m Kirthi, a Senior Data Engineer at IBM with over 7 years of experience working across GCP, AWS, and Azure ecosystems. I’ve helped global clients like American Express, New York Life, and Walmart build robust data pipelines, migrate legacy systems, and modernize their data infrastructure using Python, PySpark, SQL, and BigQuery. My expertise includes data migration, ETL design, cloud data architecture, and performance optimization. I’ve also worked extensively on Delta Lake, AWS Glue, Databricks, and Kafka streaming for real-time and batch processing. On Topmate, I guide professionals and aspiring data engineers on: Transitioning into data engineering from other tech roles Building PySpark and cloud-based data pipelines Preparing for data engineering interviews (IBM / Accenture / product-based roles) Understanding real-world data architecture and best practices If you’re looking to grow your data engineering career, optimize your projects or resume, or simply want a clear roadmap to learn cloud + big data, let’s connect — I’d be happy to mentor you.
