X Career
Brady previously worked in quantitative research at Cumberland, part of DRW, and helped build the DeFi trading firm Ergonia. He founded Meridian, an interface for financial markets, before joining The Bot Company in August 2026 to work on machine learning and robotics. His former Meridian biography records a Harvard statistics degree; his current personal site gives the later career chronology.[1][4][5]
Contributions
Optimization Arena gives participants a reproducible environment and a numerical objective. Brady’s account emphasizes that strong challenge design needs an elegant verifier, enough realism to be useful and few opportunities to overfit accidental details. His experience running the competitions connects agent orchestration with the design of an experiment and its measurement. The project moved to Paradigm as Paradigm Puzzles in July 2026.[2][5]
Ideas
In Notes on the Software Factory, Brady argues for giving agents development tools, tests and feedback rather than stopping at text generation. He discusses critics, memory, integration tests and the bottlenecks that limit longer tasks. The essay is a practical account of his workflow and its remaining weaknesses, including business context, continual learning and always-on operation.[3]

Read the explanation of how a challenge is scored, then compare it with the discussion of overfitting and verifier design. It is a useful introduction to evaluating an agent by reproducible outcomes instead of how convincing its answer sounds.
