Profile

Founder and Principal AI Product / Systems Architect building The Human Code, a founder-led multi-repository engineering program spanning AI product architecture, workflow software, identity and authorization, governed model execution, PostgreSQL/Supabase systems, accessibility, provenance, and release engineering. I own the path from ambiguous human problem to product model, architecture, implementation, verification, deployment evidence, and rollback - with explicit boundaries around authority, privacy, maturity, and what the system has not yet proven.

30 hosted project/service surfaces

6 VERCEL PROJECTS · 24 RENDER SERVICES

Production, preview, staging, verification, and support surfaces across the connected deployment estate.

Scale boundary: these are dated engineering-estate metrics, not counts of independent products, customers, users, or personally hand-written features. Open or draft work is not represented as shipped.

Selected accomplishments

  • Continuity Wallet: built a public Platform Core connecting identity, consent, routing, receipts, history, packet/export behavior, and portability; advanced release engineering through identity transition, isolation evidence, backup-first migration, restore rehearsal, rollback, and controlled re-release.
  • Business Pages / Business AI: productized a reusable platform family across local services, merchant claim/authority verification, configuration, bilingual experiences, lead workflows, provider handoffs, customer engagement, AI-readiness offers, and atomic capability revocation.
  • Human Pages v1: built path-based public profiles with Supabase magic-link identity, permanent usernames, owner-only drafts, explicit publish state, immutable versions, restore-to-draft, guestbook moderation, authenticated reporting, and reserved-route protection.
  • Governed AI execution: designed HCOS and the provider/capability/policy/routing/receipt model so providers remain replaceable while human authority, provenance, verification, retention, and continuity remain explicit.
  • Platform routing: converted contextual assistance and QR/deep-link entry into a registry-driven public-platform invariant with safe sign-in continuity, reserved-route precedence, and build-time coverage checks.
  • Cross-domain productization: built and tested public-safe or synthetic systems across behavioral health, family services, workforce, recovery operations, legal continuity, housing, reflection, and public identity while preserving domain-specific authority boundaries.
  • OD X7 research/evaluation tooling: built a seven-axis evidence lens, 25-claim development calibration, masked review/judge packet infrastructure, and a bounded independent-review harness; independent validation remains explicitly unclaimed until external evidence exists.
  • Security & trust engineering: built RLS-oriented access boundaries, protected-identifier HMAC scanning, public-safety checks, ontology/ecosystem validation, fail-closed configuration behavior, and explicit no-claim maturity gates.
  • Behavioral verification: built real headless-browser interaction tests that click controls, verify populated outcomes, exercise contextual states, and catch routing/UI regressions rather than treating screenshots as proof.
  • Release engineering: use immutable candidates, preview-first verification, Vercel/Render deployment evidence, exact-revision reconciliation, migration rehearsal/rollback, production black-box checks, and concurrency admission before release.
  • Continuity architecture: built repository-backed provenance/convergence tooling for source lineage, conflicts, supersession, protected routing, validation, and explicit separation of conversational memory from accepted project state.
  • Human-first product narrative: translated architecture-heavy systems into recruiter-facing, public-safe journeys and evidence surfaces that keep implementation, verification, disclosure, and deployment maturity visibly separate.

Selected product & systems work

Founder & Principal AI Product / Systems Architect · The Human Code 2023-Present

  • Design and build human-centered workflow products and governance infrastructure spanning behavioral health, family services, workforce, housing, legal continuity, public-facing identity, and AI-agent control.
  • Translate ambiguous needs into product requirements, state transitions, role/authority rules, data contracts, acceptance criteria, test cases, risk boundaries, implementation plans, and rollback paths.
  • Use preview-first delivery with implementation, tests, documentation, specifications, exact-head verification, and explicit lifecycle status synchronized around each release.

Continuity Wallet

PRODUCTION-HOSTED PUBLIC PLATFORM CORE · CONTROLLED RELEASE EVIDENCE

Identity, consent, routing, receipts and portability, with owner-scoped isolation, backup-first migration, restore rehearsal, rollback, and controlled release handling.

Business Pages / Business AI

MAIN-INTEGRATED PLATFORM FAMILY

Reusable merchant/service platform spanning claim and authority verification, configuration, bilingual experiences, lead workflows, provider handoffs, AI-readiness offers, and atomic capability revocation.

Human Pages v1

MAIN-INTEGRATED / PRODUCTION-HOSTED PUBLIC PROFILE

Path-based public profiles with magic-link identity, permanent usernames, owner-only drafts, explicit publish state, immutable versions, moderation, reporting, and reserved-route protection.

CourtChain

ACTIVE BUILD / GOVERNED LEGAL WORKFLOW

Legal matter architecture spanning identity, timelines, evidence, packet generation, authorization boundaries, recovery, provenance, and synthetic guided journeys with explicit separation of user assertions, drafts, filings, and court acceptance.

HCOS + Continuity Runtime Platform

REFERENCE IMPLEMENTATION / DEVELOPMENT RUNTIME

Provider-neutral AI control plus typed authenticated events, snapshots, replay, diffs, planning, telemetry, governance reporting, Object DNA, and ownership-aware runtime state; durable production persistence remains separately gated.

Universal Context Router

MAIN-INTEGRATED PUBLIC CONTEXT ROUTING

Registry-driven contextual assistance, QR/deep links, safe sign-in continuity, reserved-route precedence, and coverage enforcement across deployable public surfaces.

Additional systems: Human Code Continuity Spine · OD X7 Evaluation Infrastructure · Workforce Continuity · Human Exchange / Tap Core · Smart Family Flow · Recovery Operations · HomeKey.

Engineering, governance & release work

  • AI governance: provider-independent routing, capability/policy separation, explicit human authority, consensus boundaries, execution receipts, memory disposition, and provider-substitution continuity.
  • Data & access: Supabase/PostgreSQL, RLS-oriented access boundaries, magic-link auth, path-based routing, reserved namespaces, immutable publication versions, moderation/reporting flows.
  • Security & safety: protected-identifier HMAC scanners, public-safety scans, fail-closed secrets/configuration behavior, source-boundary rules, no-claim maturity discipline.
  • Verification: Node tests, Python checks, JSON/schema validation, real headless-browser interactions, HTML parsing, CI contracts, exact-head verification, deployment metadata checks.
  • Accessibility & UX: mobile-first vertical layouts, keyboard-operable controls, visible focus, reduced-motion support, dialog semantics, bounded deep links, plain-language workflows.
  • Release engineering: Git/GitHub branches and PRs, GitHub Actions, Vercel preview/production deployments, rollback plans, concurrency checks, source/preview/production truth separation.
