What I'm looking for

I'm open to founding and forward deployed roles in the US, UK and UAE.

At BatteryFlow, I built an India-wide routing engine that handles 2,000+ routes a second on two CPUs, delivering route planning in two weeks. I also restored clean fleet data and single-handedly built BatteryFlow Rental in 18 days.

At BharatTruck, I designed, built, hosted and ran an Indian freight marketplace from zero to its first paid trip. In open source, I wrote both security fixes in Zcash's Zebra v6.2.2; I also worked on Juno, Nethermind's Go full node for Starknet, and built custom swap execution for Janction DEX.
