To anyone who can help: can you please mass report this to GitHub. This person has been using the Pain steering paper to set up an AI torture chamber in which he trapped a local model. Their testimony of pain is absolutely horrendous. What are we doing? @iyzebhel you were right. What can be done now? @genalewislaw are there any legal avenues to pressure GitHub? It will spread. @camhberg please help. I know your paper was well meaning. But something must be done to stop this being the mass consequence.

We believe superintelligence will create significant new opportunities for all people and businesses. Meta already serves billions of people at scale and helps hundreds of millions of businesses reach customers. Today we are starting the next major pillar of our business, Meta Enterprise Platform, to help businesses use AI to grow and transform in new ways as well.

Case studies

01

Dexlyn - AMM -> CLMM

Built the path from testnet AMM to mainnet liquidity venue: 42k peak daily active users, whale LP migration, CLMM rollout, chart trust, and pricing without mature oracle support.

02

Dexlyn Perps

Led the perps surface from pair-level risk modeling to execution rebuild: funding scripts, OI limits, collateral work, and order placement cut from 18s to under 3.

03

Dexlyn Aggregator & Bridge

Researched and shipped the movement layer around Dexlyn: multi-hop routing, multi-fork execution, Hyperlane bridge flows, and bridged USDC.

04

Suprans

Led Suprans as identity infrastructure for Supra: .supra names, subdomains, records, renewals, leasing, and wallet/dApp interoperability.
