Projects

≡ index / about / projects

This page lists projects that I have worked on. Many of these are programming ones and so are code repositories. I recently left GitHub as my primary forge and am trying to build this page as the new landing page.

You should complement these lists with my blog and journal since some projects of mine are just present there as write ups.

1. Statistics

A few overall statistics based on the repositories listed on this page.

1.1. Language Use Statistics

Removing HTML and Jupyter Notebook. It seems like there are a few problems here and I might need to blacklist a few files. For example, I don't think I have written more TeX than Emacs Lisp. Also JS seems to be over-represented.

2. Projects

Here I am nesting projects under some crude first-pass categorization, at the cost of some overlaps.

I run a crawler over a master data file that helps me generate this page. You might find it helpful to use the Table of Content on this page for jumping to different sections of interest.

2.1. Machine Learning

Machine Learning and Artificial Intelligence has been my primary employable skill. This also means many categories of my work could have some flavor of ML. While I have tried to put out some broad items here, it's recommend to do a search for #ML tag on this page to know items outside of this section. Also check out blog and journal posts with ML tags.

2.1.1. Speech Tech & Conversational AI

Many of the projects in this area are from the time I was working at Skit.ai, 2018-2024. Because of this reason certain descriptions might not make sense when read in isolation. I will improve them with time.
