About

I am a Principal Engineer & ClickHouse Expert with 15+ years of experience designing and scaling petabyte-scale data systems. My expertise lies in building real-time analytics platforms using ClickHouse, Apache Iceberg, Trino, and Kafka, with hands-on coding in Python, Go, and Java. I’ve led teams and initiatives at companies like AlphaSense, Policybazaar, O4S, and BetterWealth — building high-performance ETL pipelines (500GB+ daily ingestion), optimizing ClickHouse storage/query performance by 50%, and delivering sub-second query latency on billions of rows. Skilled at schema evolution, partitioning, indexing strategies, and query optimization, I specialize in cloud-native architectures (Kubernetes, AWS) and cost-optimized scaling. I thrive in startup and enterprise environments alike, bridging hands-on engineering with architectural leadership to deliver resilient, fault-tolerant, and cost-effective data platforms.
