Available to hire
Hi, I’m Raman Singh Malhotra, a data engineer with 5 years of experience designing and scaling cloud-native data platforms across AWS, Databricks, and Snowflake. I build real-time and batch ETL pipelines, optimize query performance, and enable data-driven decision-making for Fortune 500 clients. I’m passionate about transforming raw data into high-quality analytical assets and leading end-to-end data lifecycle automation.
I enjoy collaborating with cross-functional teams—ML, DevOps, and analytics—to deliver fault-tolerant pipelines and scalable solutions. In my spare time, I explore new data tools and optimize processes to extract maximum value from data.
