# What I'm currently up to
**Last updated:** March 2026

## What is this page?
This page is a list of the things I'm currently doing, following the format laid out by the [/now](https://nownownow.com/about) movement.

This page has a dual purpose:
- It helps you know what I'm up to (if you're so inclined)
- It helps me be aware of all the stuff I'm doing 😶‍🌫️

## 🎯 Building Kairos

I'm Co-Director and CEO of [Kairos](https://kairos-project.org/), an AI safety fieldbuilding organization focused on supporting talent to work on risks from advanced AI. We spun off from CEA in mid-2024 and have been growing fast since.

Some of the things I'm focusing on:
- **Running [SPAR Spring 2026](https://sparai.org):** 136 projects pairing 400+ mentees with 120+ mentors. This is the largest round of any AI safety research fellowship to date.
- **Scaling the team:** We're growing from 4 people to 8+, hiring across generalist, operations, and director roles.
- **Rewriting our internal stack:** Migrating all of Kairos's internal tooling to a monorepo built on [Convex](https://convex.dev/), replacing a patchwork of Airtable bases and scripts.

## 🔐 Side projects

I have a couple of Rust projects I work on when I have time:

- **[Tacet](https://tacet.sh):** A Bayesian timing side-channel detection library. It uses principled uncertainty quantification to produce three-way verdicts (pass/fail/inconclusive) instead of forcing binary decisions under noisy conditions. I submitted a paper to USENIX Security '26.
- **[OxCrypt](https://github.com/agucova/oxcrypt):** A fast, memory-safe [Cryptomator](https://cryptomator.org/) client. I wrote the crypto core a while back and recently picked it back up, adding FUSE, WebDAV, NFS, and CLI support. Roughly 2–3× faster than the official Java client on metadata-heavy operations.

## 📚 Finishing my degree

This is my last semester of Computer Science Engineering at UC Chile. I'm taking a databases course (IIC3413) and an innovation & entrepreneurship course (ING2030), where my team is working on a project related to children's literacy in Chile. Nearly done!
