Summary

Twenty years building, hosting, securing, and rescuing production software up to Fortune 500 scale, most recently as the sole Senior Solutions Architect for Pressable's (Automattic) highest-value enterprise portfolio. Engineer of record across stacks: web and WordPress at enterprise scale, iOS and Android apps, Python and AI systems, and infrastructure. An AI-augmented practice puts my time on architecture, judgment, and review, so the work spans stacks and industries.

AI-Augmented Engineering Practice

Author of A Structural Theory of Harnesses (April 2026), the first theoretical account of harness engineering as a named discipline (DOI 10.5281/zenodo.19570642). Claude Code has been daily production infrastructure since September 2025.
Multi-model adversarial code review: every significant change is reviewed by independent model lineages, because a reviewer sharing the author's training distribution shares its blind spots. Layered with deterministic checks, grounding against source, and human sign-off — systems built to be governed, not trusted.
Supporting tooling shipped open source: anneal-memory and Levain, both on PyPI. The result is AI-assisted delivery speed without the unreviewed-code debt that usually comes with it.

Experience

Clapham Digital LLC — Founder · Columbus, OH (Remote)

February 2026 – Present · Accepting engagements

My own practice: software engineering and architecture for client organizations, including WordPress engineering, hosting, security, and performance, plus consumer iOS and Android apps shipped on the App Store and Google Play.

Pressable (Automattic) — Senior Solutions Architect / Technical Account Manager

October 2024 – July 2026 · Remote

Sole technical account manager for Pressable's highest-value enterprise WordPress portfolio. Authored tooling that shipped as how the whole organization operated.

WordPress.com and WordPress VIP to managed-host migration tooling, including automated Gutenberg block replacement. Thousands of migrations through the WP Engine / Automattic disruption; trained support teams on the playbook.
Authored the org's load-testing and capacity-planning tool, its primary instrument for infrastructure sizing and performance validation. Released publicly as MicroChaos CLI (PHP, WP-CLI) — load testing from inside WordPress for managed environments where external tools are blocked, simulating authenticated users, WooCommerce flows, REST endpoints, and warm or cold cache.
WooCommerce performance engineering that cut full seconds off checkout flows and preserved multi-six-figure accounts that were actively churning.
Performance-audit workshop pattern — backend profiling, architecture review, tailored remediation. Adopted org-wide; enterprise customers called it more valuable than paid consulting engagements.
100+ competitive technical evaluations and enterprise pilots — frontend comparison, backend architecture analysis, empirical capacity math — roughly 45 through a harness I automated.
Partnered with Fortune 500 technical leadership through C-suite on infrastructure strategy, translating architecture tradeoffs into revenue, risk, and cost terms. Delivered a live full-stack WordPress performance walkthrough for The WP Minute (May 2026).
