About
Hi, I'm Raj. I'm an engineer by training and a product person by instinct. I work on invideo, where we're building the agents and tools that serious creative work will run on.
I like talking to the people who use what I build as much as building it. And I like the part where nobody knows the answer yet, and we have to work it out.
Most of my days are engineering. What I'm trying to get better at is everything around it: deciding what's worth building, getting it in front of the right people, how it lands with them, and whether the numbers work.
I'm in Mumbai. If you're around and you write Elixir or Rust, come to the meetups; I co-host Rust Mumbai and Elixir Mumbai. I also give talks now and then.
Outside work I build things, some because they're useful and some because I want to see how they work. The one I've stuck with longest is Winterfell, a Kubernetes cluster at home. It now runs a lot of my digital life.
Most mornings start with coffee and Hacker News, and what I want to keep goes into my bookmarks. I read a lot; right now it's Surely You're Joking, Mr. Feynman!. I travel when I can, and some trips turn into travelogues.
Things I keep coming back to
- You can just do things.
- What's the most ambitious version of this?
- Leverage over busyness.
- Systems over willpower.
- Long games, chosen slowly.
If you want to know more
- Writing: notes on what I build, and whatever I'm curious about.
- Books: what I've read, and what stuck.
- Bookmarks: the best of what I find on the web.
- Contrail: every flight I've taken, on a globe.
- Travelogues: trips, frame by frame.
