Devin Pellegrino
Knowledge Systems & Persistent AI Agents for Open-Ended Domains
From FDA-cleared medical technology operations to a live 37-agent operating system — built on the NERO Method, with the work published and dated since 2023.
What I Do
Systems architecture across regulated medical technology, production AI, and public education — every claim traceable.
Medical Technology
Director of Engineering at Brain Ultimate, an FDA-cleared TMS medical-device company. I've trained 50+ clinics and hospitals across the country on deployment and plasticity mechanics — including Butler Hospital, where I personally installed 75% of the TMS wing.

AI Architect of 911 PAWS — I designed the 13-agent anti-hallucination architecture behind a live, paid consumer health product. And I run the NERO system: 37 persistent domain agents under apex orchestration, governed like production infrastructure.

Three years of public, dated releases: 33+ GPT agents, 16 prompt libraries, a formal curriculum, 50+ recorded sessions, and the NI-NOTION methodology series — plus a community of 500+ builders.

Most AI systems fail in open-ended domains because they're designed top-down: generate an architecture, force behavior into it, watch it drift. I work in the opposite direction — master the domain manually, reverse-engineer the expertise into explicit structure, and let every correction become a permanent rule.
The industry has proven long-horizon agentic AI where a verifier exists — software and mathematics, where the answer compiles or checks. Anything with a verifier can be automated. I work on the open-ended rest, which is most of everything else — operations, clinical training, logistics, education — where there is no verifier and the only ground truth is human mastery.
Context Engineering
Human-authored knowledge maps as ground truth — deterministic rules instead of vibes.
Agentic Engineering
Versioned agent lifecycles — agents that write their own next version and never lose state.
Knowledge Engineering
Expert domains converted into structured surrogate models that AI can operate on reliably.
Prompt Engineering
The foundation — three years of public, dated releases with 560+ GitHub stars of validation.
Two Substrates, Both Taught
The four disciplines sit on two physical systems — a human mind and a language model. I teach the mechanics of both.
Band Mechanics
The neuroscience of attention, state, and plasticity — how to hold the sustained, coherent focus that mastering a domain actually requires. Taught to Insiders and to clinicians nationally.
BackgroundHyperspace Engineering
The mechanical reality of surrogate modeling in a language model's latent space — how meaning is positioned and traversed, why the prompt's origin shapes everything downstream, and how predictable surrogate layers are built on top of the base model.
The principlesTrack Record
Public, dated, and cumulative — every phase built on the last.
Released the Advanced-GPTs suite — 33 zero-shot agents. Nobody in the community could crack the prompt protection, so they came to learn how it was built. Founded Nerority LLC. Teaching from mastery began here.
The techniques behind the GPTs released as a formal curriculum. The 600+ page Hyperspace Codex codifies Hyperspace Engineering — surrogate modeling in latent space — alongside 16 libraries and 13 frameworks. Insider program launches; the core group that's still here today joins.
Band Mechanics and Hyperspace Engineering taught as the two substrates of the method — to Insiders, and Band Mechanics to clinicians nationally. Insiders meet in person. The 911 PAWS multi-agent architecture designed for Pet Portal AI.
The 22-entry NI-NOTION series written live for Insiders. 911 PAWS ships to paying customers. The 37-agent NERO system runs under apex orchestration. The founding Insiders are still here, 2.5+ years in.
Devin has been absolutely transformative for both my career and my personal life. I've gone from being a user to crafting complex systems and workflows that have redefined what I'm capable of professionally.
Where to Start
Hire me for hands-on systems work, read the case studies with the numbers, or join a community of builders who've been running the method for years.
