AI engineering

Design engineering, AI systems & backend automation

ZtotheZ Design Engineering

Open source · v2.0.3 published

A local-first Agent Skill, MCP server, CLI, and deterministic UI quality gate.

An independently authored design-engineering system that converts product intent, truthful interface state, information hierarchy, architecture, accessibility, and browser behavior into enforceable contracts. It provides 20 scoped MCP tools, BM25 knowledge retrieval, repository audits, Chromium verification, evidence-separated reviews, bounded repair, offline packaging, and clean-room independence checks. The v2.0.3 release passed 168 automated tests and qualified contained delivery pilots across SceneStart, AegisOPS, and Azure Optimizer without presenting automated evidence as representative-user validation.

ZtotheZ Portfolio Platform

Live production · iterative rebuild

A portfolio platform that records the move from handcrafted static pages to modern server-rendered application architecture.

The first version was a multi-page HTML/CSS/JavaScript site with reusable header and footer components, security-focused project sections, and manually managed assets. The next rehaul introduced utility-first Tailwind, responsive navigation, richer metadata, and deployment hardening. A Gemini/AI Studio branch explored Angular 21 SSR, Angular Material/CDK, Tailwind, Motion, and a Gemini API integration path. The current version uses TanStack Start, React, TypeScript, Tailwind CSS, Nitro/Node.js SSR, route-level SEO metadata, responsive navigation, and local asset bundling. The delivery workflow runs through Git: changes are committed and pushed, fetched into the deployment workspace, reviewed and approved, then built and applied to production through cPanel Passenger.

Source repository private; the live platform and its architecture are public.

Professional recommendation

Evidence from a systems delivery

A testimonial from The Library of Alexandria project, where I worked as a technical consultant and TrueNAS systems builder. The work covered the architecture, assembly, configuration, and operational handover of the media-archive storage system.
