About me
Rohan Chaudhari
Senior Software Engineer — Data & ML Platforms
Senior engineer with 6+ years designing and operating large-scale data & ML systems end-to-end — ingestion, orchestration, warehousing, and production pipelines. I've built platforms processing 4M+ geospatial data arrays and sustaining ingestion at 13 TB every 5 days.
I've been a founding engineer at 2 startups (one acquired). That means I know what it takes to go from zero to a product that survives contact with real customers — not just technically, but strategically. When you're early, every decision has a cost. I help founders spend those decisions wisely.
Today, I work with early-stage founders — especially those building data-heavy or AI-powered products — to scope ruthlessly, build fast, and ship something their first customer will actually pay for.
