I’m a senior data engineer at Citi in Bengaluru, with 8+ years of building and fixing data systems. Most of my days go into Spark. I’m usually the one who gets pulled in when a job is slow, expensive, or failing every night, and I’ve cut resource usage on some of those by up to 90%. Then I build the tooling so nobody has to dig through those logs by hand again.

Before Citi, I spent four years at Sahaj Software owning terabyte-scale ad-tech pipelines on AWS EMR and Airflow, and before that, three years at TCS building real-time pricing APIs for Cummins.

Outside work, I’ve contributed to Apache Airflow, was a maintainer at CRI-O and DuckDuckGo, and did Google Summer of Code with TEAMMATES at NUS. When a problem annoys me enough, I turn it into a tool, like spot-optimizer (11k+ downloads) or uv-bundler, and I write about Spark internals, databases, and functional programming.

Always happy to talk data, open source, or side projects. Say hello on GitHub, Medium, or LinkedIn.
