✨ Hello! ✨

I build systems and tools for Machine Learning -- previously I worked at GitHub on GitHub Copilot building evals & infra for tab completion and Chat, and did open research with Cohere Labs on Aya.

Follow me on X for updates.

Past Research

Venue Paper Contributions
Nature 2026 Humanity's Last Exam Contributed a difficult math & statistics question about theoretical max damage in Old School Runescape
ACL 2024 (Best Paper Award) Aya Model: An Instruction Finetuned Open-Access Multilingual Language Model Data Engineering to create the Aya Human Annotated set of the Aya eval suite: dataset
ACL 2024 (1st Author) Aya Dataset: An Open-Access Collection for Multilingual Instruction Tuning Designed, built, and scaled out the backend for an open data annotation platform for over 3000 contributors and 300,000+ annotations for training multilingual instruction-tuned LLMs on mixed-resource languages: repo. Co-created the Aya Score to encourage participants to incorporate more edits during annotation, increasing average annotation length by >50%
CSCW 2017 Crowd Guilds: Worker-led Reputation and Feedback on Crowdsourcing Platforms Helped design a reputation system for workers and requesters to gain experience, receive higher wages and higher quality work
