Specification-Driven Development Framework

Governing AI-generated software
with formal specification

A complete specification and assurance framework for auditable AI-developed software: a formal Language Specification (v1.3.1 + Addendum A), 17 normative styles, Phase 0 problem definition, Technical Verification Gates (TVG), requirement-to-test traceability, four conformance levels, and tamper-evident evidence packages (HMAC-SHA256).

Concept

Specification-Induced Speculation — A formally defined failure mode in AI code generation, distinct from hallucination; describes the feedback loop by which accepted speculation degrades successive model generations.

Theorem

Bounded Stochasticity Theorem — Relates deterministic specifications to the behavior of stochastic generators, establishing a mathematical foundation for SDPF's verification approach.

Method

Weak Node Discovery — A protected-asset-first reverse-reachability method identifying underprotected trusted nodes whose compromise reaches crown-jewel assets.

Security Platform Portfolio

Cybersecurity · Architecture

PRIME-SENTINEL / Weak Node Discovery

Consequence-driven security architecture using a protected-asset-first reverse-reachability method. Identifies underprotected trusted nodes whose compromise can reach crown-jewel assets, enabling consequence-based monitoring and remediation prioritization.

Threat Detection · Response

SGI Security Platform

Comprehensive threat detection and response system with network security modules, persistence and anti-forensics capabilities, and an adversarial-simulation framework for penetration testing.

Compliance · Verification

BSVE — Bounded Substrate Verification Engine

Security verification and compliance framework with graph-based security-surface enumeration, invariant evaluation, evidence-ledger tracking, and contract-enforcement mechanisms. Includes SBOM and compliance documentation.

Red Team · Adversarial Simulation

UCDE Sentinel

Authorized penetration-testing tooling for covert tunneling, USB initial-access and propagation simulation, and API-hooking / process-masquerade techniques with training and policy documentation.

AI Governance · Specification

SDPF Agent Controller

Agent execution framework with state persistence, evidence collection, verification and test-vector generation, spec-to-code conversion, and CI/CD workflows for security agents.

Industrial · ICS / SCADA

In-Control

Industrial controller security framework with sensor adapter, authentication gate, persistence manager, watchdog systems, and secured mission-loop execution for ICS/SCADA environments.

Pharmaceutical · Compliance

Pharma Logic CT-DMS

Compliance tracking system with FDA 21 CFR Part 11-compliant workflows and GxP-compliant data handling procedures for pharmaceutical clinical trials.

Bioinformatics · Document Processing

ProFold & CodeJuicer

ProFold: bioinformatics security pipeline with hypothesis-testing and validation frameworks. CodeJuicer: document-processing and OCR pipeline with sandboxed execution for untrusted code and batch processing.

Experience

2021 — Present

Principal Security Architect

Independent Consultant
  • Designed and delivered enterprise-scale security and assurance platforms from concept to production across industrial, bioinformatics, pharmaceutical, and IT security domains.
  • Established specification-driven development practices and reusable frameworks; originated Weak Node Discovery, a protected-asset-first method for finding trusted nodes with high-consequence exposure.
  • Advised leadership on security and AI-governance roadmaps; created and published the SDPF framework at sdpf.dev.
2017 — 2021

Software Quality Assurance Lead

Merck — Consultant · FDA-regulated clinical software (21 CFR Part 11, IEC 62304)
  • Established SQA program for a clinical decision support platform from initial development through FDA 510(k) submission, with zero major findings at pre-submission inspection.
  • Designed and executed a requirements traceability matrix covering 847 requirements across four software components, achieving 100% bidirectional coverage before submission.
  • Reduced post-release software defect rate by 44% through structured root cause analysis and process improvement initiatives using Lean Six Sigma tools.
  • Managed external IV&V contractor relationship and integrated findings into the software development lifecycle without program delay.
2014 — 2017

Electrical Engineer (Spacecraft) — SQA & IV&V

Lockheed Martin · Space systems and launch vehicle software verification
  • Performed IV&V and verification activities on satellite flight software and hardware (IntelSat).
  • Developed and maintained software verification plans, procedures, and closure evidence packages accepted by NASA program management and independent safety review boards.
  • Led root cause analysis following a pre-launch software verification anomaly; corrective actions were incorporated into programme standards.
  • Maintained bidirectional traceability between system requirements, software requirements, and verification evidence in collaboration with hardware and systems engineers.
