About

I'm Aadharsh Pannirselvam. I research and invest at Archetype, 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, with the same content as Markdown at /resume.md and as JSON Resume at /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: my photographs, each with its camera settings and film recipe.
• /writing: longform notes.
• /lwe: explainers of applied cryptography, written as chats with live demos.
• /garage: experiments and measurements from building the site.
• /lens: a tool that shows how a machine reads any URL.
• /serendipity: a shared pool of events worth going to.

Agents can read the whole map at /llms.txt and call the site from code through the endpoints on /developers.
