I help businesses build and maintain production web applications — from PWAs and offline-first architectures to backend APIs and CI/CD tooling. Over 20+ years I've worked across scientific R&D, test & measurement, manufacturing, insurance, and e-commerce, so I'm comfortable translating between "what the business needs" and "what the code has to do."

• 🛠️ Current Focus: Progressive Web Apps, offline-first architecture, developer tooling
• 🌍 Location: USA (Remote)
• 💼 Services: Full-stack development, technical auditing, team augmentation

JavaScript

Golang

Node.js

React

Docker

MariaDB

Reference architecture for building PWAs with vanilla JS.

• What it demonstrates: Static/dynamic data handling, service-worker-based offline-first design, no framework dependency
• Stack: JavaScript, Service Workers, MariaDB (via companion Nodejs propsdb-api service)

High-performance Go data service, built as a drop-in replacement for the jam-build Node/Express service.

• What it demonstrates: Cross-language service replacement without breaking API compatibility
• Engineering details: Multi-database support (MariaDB, MySQL, PostgreSQL, SQLite, SQL Server) via GORM, Authorizer-based auth integration, optimistic locking with version-conflict detection, tested with testcontainers, shipped as a public Docker image
• Stack: Go, Fiber, GORM, Docker

Selector-based HTML snapshot tool for pre-rendering and SEO.

• Proof: 129 stars · 16 forks — actively used by other developers
• Stack: Node.js, Puppeteer/Playwright — sources from sitemap.xml, sitemap-index, robots.txt, or arbitrary input

Build-time library for generating CSP (Content Security Policy) script/style hashes.

• What it demonstrates: Security-conscious tooling — solves a real, easy-to-get-wrong problem (keeping CSP headers in sync with build output) rather than a toy project
• Proof: 1000+ weekly npm downloads — actively used by other developers
• Stack: Node.js, integrates into Gulp/build pipelines, published on npm

I am currently accepting select engineering contracts and technical consultation roles.
