# Work

You should check out [my current projects](https://nilesh.trivedi.link/master#now) and [my GitHub profile](https://github.com/nileshtrivedi).

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 Meta 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.

## 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](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](https://www.producthunt.com/posts/learnawesome) and [Hacker News](https://news.ycombinator.com/item?id=23795779). I discontinued this in 2024 to rethink learning in the age of AI.

I made a [physics playground app](https://mechasim.herokuapp.com) 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](https://hasgeek.tv/jsfoo/2013-2/688-interactive-physics-simulation-in-the-browser-what-i-learned).

Inspired from [Bret Victor's famous talk](http://vimeo.com/36579366), 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.
