Key facts

Paper on Ticket Pricing

In March 2018, listing Meta Platforms and Northwestern University’s Kellogg School of Management as his affiliations, he posted the paper “Indices for Dynamic Pricing in the Event Ticketing Industry” on SSRN, studying dynamic pricing indices for sports event tickets.⁠[1]

Economics Paper and Explainer Article

His article “Understanding LLMs from Scratch Using Middle School Math” was among the stories Medium listed as most shared across the internet in 2024.⁠[3][4]

September–October 2025: Reinforcement Learning Paper and Commentary

In September 2025 he posted a sole-authored arXiv paper giving a self-contained, from-scratch exposition of key reinforcement learning algorithms for instruction tuning of models and outlining future directions with GRAPE; the paper was revised that October.⁠[5]

The same month he was among the co-authors of CRAG-MM, a multi-modal, multi-turn retrieval-augmented generation benchmark for wearable scenarios such as smart glasses.⁠[7]

Modality Maturity Index

In August 2026 he was first author, with Dieuwke Hupkes and Sloan Strader, of the Modality Maturity Index, a benchmark for assessing the multimodal capabilities of omni models.⁠[8]

Leaving Meta to Launch Ndoc

He said he had spent 7.8 years at Meta and wanted to work on his own projects.⁠[9]

On October 27, 2026, his departure from Meta became public along with the launch of Ndoc, an AI-native alternative to Microsoft Office and Google Workspace; at Meta he had focused on reinforcement learning and on evaluating whether AI output can be trusted.⁠[10]

Ndoc then had three staff and no outside funding, ran an enterprise pilot and a waitlist alpha, and planned a beta within weeks and a full launch the next year.⁠[10]

Ndoc documents can be exported as a single “.ndoc.html” file that opens in a browser.⁠[11]

Its file format specification is released under the Apache 2.0 license.⁠[12]

He said Ndoc is built and fine-tuned on a mix of open-source models, which he said makes it cheaper to run than tools built on frontier models.⁠[11]

Advisory Role: BayPine

He is a member of the Digital Advisory Board of the private equity firm BayPine.⁠[13]
