I’m Amit, founder at ReviewNB & GroNav. I like building simple, useful things. When I’m not orchestrating LLMs (aka working), you’ll find me playing badminton, hiking, or making up stories for our 5-year-old daughter.
ReviewNB is a collaboration tool for data scientists, launched in 2018 and going strong. It is trusted by DS & ML teams at Apple, AirBnB, Spotify, Meta, Lyft, NASA JPL & many more!
Before starting ReviewNB, I worked on the Amazon Music team in Seattle and later helped build the location stack at HyperTrack. A long time ago, I earned my Master’s in Software Engineering from Carnegie Mellon.
I’ve been manually writing code for 20+ years like a caveman. Now I use Claude Code, Gemini CLI, and Codex — they do much of the heavy lifting, while I focus on reviewing, refining, and thinking about what we’re actually building.
From the caveman era – I am (or was?) proficient in Python/Django, Rails, and Vue.js. I’ve built & managed infrastructure at scale with <all the buzzwords go here>. Strong proponent of automated testing & code reviews as they help us quickly build reliable software & learn from each other. I’m also fascinated by the human side of software engineering – development processes, collaboration tools and such.
Outside of ReviewNB, I occasionally help companies solve specific problems E.g. I helped GitLab build executable runbooks for DevOps.
