CASE STUDIES

The Work

Four case studies with the numbers. Regulated medical technology, a live multi-agent operating system, product architecture, and three years of public teaching — each one Problem → Approach → Result.

01 MEDICAL TECHNOLOGY

Trained 50+ clinics and hospitals nationwide on FDA-cleared TMS deployment and plasticity mechanics.

Role — Director of Engineering, Brain Ultimate Timeframe — Oct 2023 → present Domain — FDA-cleared neuromodulation
PROBLEM

A growing medical-device company — FDA 510(k) cleared for MDD and OCD — needed repeatable technical operations: installation, clinician training, documentation, and internal knowledge systems across a complex, regulated product line.

APPROACH

Standardized the install-and-train process end to end, built the internal knowledge and operations architecture on a zero-redundancy standard — every fact lives in exactly one place — and delivered hands-on training on device operation and the underlying neuroplasticity mechanics.

RESULT

50+ clinics and hospitals trained across the country, including Butler Hospital's TMS program — where I personally installed 75% of the TMS wing. A regulated deployment operation that runs as a repeatable system.

02 AI SYSTEMS

A self-referential multi-agent operating system: 37 persistent domain agents, live, under apex orchestration.

PROBLEM

AI agents drift, forget, and fail outside software engineering — the one domain where a compiler verifies correctness. In open-ended knowledge work there is no automatic verifier, so most agent systems quietly decay.

APPROACH

The NERO Method: a versioned agent lifecycle — instantiate, operate, correct at the exact point of divergence, capture the next version. Progressive complexity ramping. Deterministic rule encoding, where every correction becomes a permanent constraint. Documented publicly across the 22-entry NI-NOTION series.

RESULT

37 persistent domain agents across six operational planes — personal operations, method R&D, community and business ops, and two companies — coordinated by an apex orchestration agent governing by reconciliation, not command. Strict control-plane / data-plane separation, a three-layer state model, and verify-before-write with read-back on every shared surface. Flagship demo: a task agent evolved through 9 versions to autonomously manage 115+ active tasks with zero manual board management.

03 PRODUCT ARCHITECTURE

Designed the complete prompt and agent architecture for an accelerator-backed animal-health AI product.

Role — Architectural Engine Lead, Pet Portal AI Timeframe — Feb 2025 → present Domain — Consumer AI product
PROBLEM

A consumer AI product advising on pet health has zero margin for confident wrong answers — the AI layer needed grounding, structure, and consistent behavior at production scale.

RESULT

Designed the entire AI solution on the prompt and agent side of the product. The venture was selected into the Plug and Play Topeka animal-health accelerator alongside Hill's Pet Nutrition (Aug 2025).

04 COMMUNITY & EDUCATION

20+ members active for 2.5+ years — set up and operating across their own domains.

APPROACH

Everything released publicly and dated since May 2023: 33+ GPT agents, 16 prompt libraries, 13 frameworks, a formal curriculum, 50+ recorded sessions, and the NI-NOTION methodology series documenting the NERO Method end to end.

RESULT

A 500+ member community with a core of 20+ Insiders continuously active for 2.5+ years — each running the method across their own life and work domains. Retention, not reach, is the metric that matters.

Every engagement is hands-on working time — we build, correct, and ship inside your actual systems. You leave with a working system and the ability to operate it.
