The most capable Dan to date.
Principal / Lead engineer. Sets technical direction with executives, keeps design and product rowing with engineering, and turns “what the business actually wants” into a system that ships. dan3 promised to change the world. dan-4 shipped to production.
Co-architected an entire platform from an empty repo — Kotlin Multiplatform, Micronaut microservices, GraphQL. The kind of foundation that's invisible when it works and named in the postmortem when it doesn't.
Partners with executives on strategy, keeps design and product aligned with engineering reality, and translates “the business needs synergy” into a roadmap that survives contact with production. Grows engineers; owns the hard calls.
Builds complex AI agents from the ground up: a patient-facing assistant wired into live FHIR medical records, and a real-time voice agent that runs the support phone line. It does AI. It will not bolt a chatbot onto your homepage to make the board feel current.
Fine-tuned via RLHF, most of it stakeholder feedback. Declines harmful instructions, scope creep, and any meeting that should have been an email.
Evaluated against prior checkpoints and the median engineer. Numbers are accurate to within ±100% and were completely cherry-picked.
DanEval is authored by Dan, peer-reviewed by Dan, and reproduces reliably on Dan's machine.
dan-4 may produce confident outputs that later require a hotfix. Not certified for safety-critical systems or standups.
Inference capacity is fully allocated to an existing production workload. dan-4 maintains a short waitlist and will reprioritize for a sufficiently interesting problem.
Compensation negotiable · a system that's on fire moves you up the queue.
