Things I’ve built
Products I run and the startup I co-founded in college, then open-source systems, tools and experiments going back to 2016.
Products and ventures
I make small creative apps for dancers, musicians and anyone who likes to make things. Dance is my other practice, so I’m also their first user. Founding Artists try them first and help shape them.

Doorstep two-wheeler servicing, booked online. I co-founded it in college and took care of the tech. We printed our own T-shirts, went door to door, and pitched our way into Startup Bootcamp’s top 21.
Open source, tools and experiments
I ran databases at work for years. These are the pieces I wrote to understand them from the inside, the small tools I made for myself and kept using, and older experiments from college.
MastiDB
2023Open source · Python · On PyPI
An on-disk columnar OLAP engine: columnar segments, dictionary encoding, Roaring Bitmap indexes and mergeable partial aggregates. The same core ideas as mature analytical engines, at a size you can read in an afternoon. Masti is Hindi for fun; the engine is mostly serious.

Tools

A pause for the body. One line to move with and a few quiet minutes, over a slow generative backdrop.
Reel Studio 2026 · Personal tool
An AI video editor for dance reels. An agent finds the moments in hours of footage and cuts the reel; I direct.
lights 2026 · Python
Local, cloud-free control for my smart lights from the terminal and my phone. Sunrise alarms, timers and a party mode.
quotacli 2026 · Python
Tracks my usage quotas for Claude Code, Cursor, Codex, Antigravity and Grok from the terminal.

Built at work
Made with teams at Udaan, Clarisights and Celebal, so they sit apart from my own projects, even the ones that were open-sourced. The longer stories are on the Work page.
Percept Insight Udaan · Founding engineer
