About Rajesh Balamohan
Highly experienced engineer with over 25 years of expertise in efficiency, and performance tuning of Big Data in on-prem, cloud platforms and gen AI platforms. My focus is on distributed systems, with a particular emphasis on performance tuning, optimization, and efficiency/cost optimization on on-prem clusters and cloud (AWS, Azure, and GCP). I am an Apache committer and PMC member with expertise in Apache Tez, Hive, Spark and ORC. I have extensive experience with performance tuning on Apache Spark, Iceberg, Tez, Hive/LLAP, and cloud platforms. Current focus has been on spearheading text-to-sql engine for different databases with LLM (OpenAI, DeepSeek R1, Sonnet, Geminie) for performance and accuracy.
