Work
Some of the things I have built over the years
You should check out my current projects and my GitHub profile.
I started programming in 1999. Starting with C, I finished many projects with Java and Javascript before discovering and falling in love with Ruby. I co-founded a B2B startup (YouSuggest.us which was a social CRM app) and learnt a lot. The companies I have worked with include GupShup, Truweight, HyperTrack, ClearTax and WhatsApp among others. My primary work has been in building intelligent and scalable software systems but I have dabbled in things like electronics hardware, algorithmic trading, aerodynamics and mathematical music theory.

aicombinator
This is a GPT-powered bot that can automate complex online tasks using both the web browser and API calls. I built this for a generative AI hackathon. This uses OpenAI, Javascript, and Puppeteer: https://github.com/aicombinator/bot
Grapher: Visual Graph Editor
This is a visual editor for nested graphs: https://codeberg.org/nilesh/grapher. This is being used by the Foresight Institute for their civilizational technology trees at https://foresight.org/tech-tree
This is built using Svelte and SVG.
This was an attempt to build a Google Maps for learning. This got some attention at ProductHunt and Hacker News. I discontinued this in 2024 to rethink learning in the age of AI.
Ruby, Rails, PostgreSQL, TailwindCSS
This is a browser extension that recommends "better" alternative products and services via in-page popups, based on community-curated lists. Available for all Chromium and Firefox-based browsers..
Javascript, Web Extension API
This is a fork of an old version of Sizzy that lets you test a webpage in different screen sizes.
I made a physics playground app for the browser, which involved vector math, Runge-Kutta integration, impulse-based constraint solver and drawing with HTML5 Canvas API. I gave a tech talk about this at JSFoo 2013.
Javascript, Canvas API, Mozilla Persona
This is a reusable UI widget which any webpage can embed for their readers to practice the content using spaced-repetition techniques. All progress is kept on localStorage so users do not need to sign up.
VueJS, Web Components
I was tech lead with them from 2009 to 2013, building the enterprise platform serving 35 million users and sending out 2 billion messages every month.
Ruby, Rails, Android, Facebook API
MapGap
I made this app at NASA Space Apps Challenge at Delhi in April 2013. It allows you to submit spots in the planet to NASA where satelite imagery is needed but missing.
Ruby, Sinatra, MongoDB & Google Maps API
BugRoulette
I made this app for events like Pullathon. It lets you randomly browse open issues from GitHub repositories that you follow.
Ruby, Sinatra, GitHub, OAuth
Inspired from Bret Victor's famous talk, I made this prototype for live coding. The idea is that as you code, the tests are run automatically and their status is immediately visible to the programmer.
