I’m a Frontend Engineer & AI Safety Architect building production-ready web applications, developer tooling, media pipelines, and context-aware security frameworks. My engineering focus lies at the intersection of modern JavaScript/TypeScript, robust CI/CD testing, and deterministic AI threat modeling.

• Languages & Core: TypeScript, JavaScript (ES6+), HTML5, CSS3 / Sass (SCSS)
• Architecture & SPA: Modular Vanilla JS/TS, Custom SPA Routers, Vite, RE:DOM
• Tooling & Environments: Node.js, FFmpeg CLI, Webpack, Babel, Docker & Docker Compose, cPanel Automation
• Testing & Quality Assurance: Jest (Unit/E2E), Vitest, Cypress, GitHub Actions (CI/CD workflows)
• AI Security & Safety: Behavioral Threat Modeling, Intent Analysis, JSON Schema Validation (AJV), Deterministic Risk Scoring

An open-source library of structured behavioral matrices, heuristics, and validation tooling designed to detect manipulation, deception, and grey-zone threats in human–AI interactions.

• What it does: Bridges the gap between static safety guardrails and fluid human psychology by targeting social engineering vectors (false urgency, fake authority, alibi manipulation).
• Tech Stack: TypeScript, Node.js, AJV (JSON Schema Validation), Jest, GitHub Actions.
• Licensing: Dual/Hybrid — BSL 1.1 (Code & Tooling) & CC BY-NC 4.0 (Dataset).

A high-performance, responsive single-page web architecture designed for audio streaming, dynamic Bandcamp integration, and custom media showcases.

• What it does: Rebuilt from legacy WordPress code (320+ engineering hours with David H. Watson), featuring custom Node.js + FFmpeg CLI pipelines for automated asset transcoding, zero-dependency SPA routing, and responsive SCSS design.
• Tech Stack: Vanilla JS, Node.js, FFmpeg, Express, Vite, Vitest, Playwright.
• Resources: YouTube Walkthrough

A robust SPA migrated to TypeScript for collecting, grouping, analyzing, and visualizing client-side JavaScript errors in real-time.

• Key Features: Global error handlers (window.onerror, fetch interception), multi-language UI (i18n), interactive charts (Chart.js), and Express/localStorage dual modes.
• DevOps: Fully containerized with multi-stage Docker builds, Docker Compose, and automated CI via GitHub Actions.

A lightweight, accessible frontend boilerplate built with Vite, TypeScript, and BEM-style responsive CSS using clamp() fluid tokens and pre-configured Vitest environment.

• Key Features: Centralized API client, keyboard-accessible UI, and pre-configured Vitest environment optimized for Windows environments.

An interactive, dependency-free frontend art performance visualizing gender equity in the workplace through dynamic SVG scales and spatial audio.

• Tech Stack: Modular plain JS, robust audio synchronization scheduling (AudioDirector), custom gravity/spiral physics animations (Dropper), and responsive CSS variable tokens.
• Resources: YouTube Walkthrough
