SAURABH KHAWAL

I’m a Data Engineer with 3+ years of experience designing scalable ETL/ELT pipelines, cloud-native data platforms, data migration solutions, and GenAI-powered applications. I focus on building reliable, secure data workflows and turning natural-language needs into actionable analytics.

At Tata Consultancy Services, I designed and implemented scalable ETL/ELT pipelines using AWS Glue, AWS Lambda, Amazon S3, Python, and SQL for enterprise analytics and reporting. I built an enterprise LLM-powered Text-to-SQL assistant enabling business users to query enterprise data using natural language, delivered as an AWS POC.

I’ve consistently improved performance and reduced cost—optimizing ETL workflows, SQL queries, and PySpark transformations to improve processing performance by up to 3x, and automating AWS operational processes with Python to reduce annual cloud expenditure by more than 2,900 dollars. I also built an AI-powered Knowledge Transfer and Service Request automation assistant, saving approximately 18k dollars annually by eliminating repetitive manual effort.

I bring strong cloud and GenAI tooling to production projects, including AWS Bedrock, RAG, and LLM-based solutions. I hold AWS Certified Data Engineer – Associate, AWS Certified Developer – Associate, and AWS Certified AI Practitioner, and I’m continuing to deepen my expertise through my MCA at ASMA Institute of Management, Pune.
