# About

I'm Aadharsh Pannirselvam. I research and invest at [Archetype](https://www.archetype.fund/), a crypto-native venture firm, and I build this site by hand in the meantime.

## Work

Most of my research time goes to cryptography and privacy-enhancing technology: fully homomorphic encryption, multi-party computation, trusted execution environments and zero-knowledge proofs. I studied at the University of Chicago. My resume is at [/resume.pdf](https://aadhar.sh/resume.pdf), with the same content as Markdown at [/resume.md](https://aadhar.sh/resume.md) and as JSON Resume at [/resume.json](https://aadhar.sh/resume.json).

## This site

aadhar.sh is a personal site styled after Windows XP and Outlook Express, written by hand and served by a Cloudflare Worker. It holds:

- [/photos](https://aadhar.sh/photos): my photographs, each with its camera settings and film recipe.
- [/writing](https://aadhar.sh/writing): longform notes.
- [/lwe](https://aadhar.sh/lwe): explainers of applied cryptography, written as chats with live demos.
- [/garage](https://aadhar.sh/garage): experiments and measurements from building the site.
- [/lens](https://aadhar.sh/lens): a tool that shows how a machine reads any URL.
- [/serendipity](https://aadhar.sh/serendipity): a shared pool of events worth going to.

Agents can read the whole map at [/llms.txt](https://aadhar.sh/llms.txt) and call the site from code through the endpoints on [/developers](https://aadhar.sh/developers).
