Front-end Developer + Design Engineer

I live at the front of the frontend.

I'm Justin -- I turn design into UI that feels alive. Sharp, warm, and built to make people actually enjoy using the thing.

Selected Work

Zero Networks

Rebuilt their web presence from scratch.

Tore down a WordPress site and rebuilt it in ExpressionEngine with a modular front-end system -- reusable blocks that let the team spin up pages fast. Shipped a custom video player, carousel, typing effect, and a jobs portal powered by the Comeet API.

  • ExpressionEngine
  • JavaScript
  • HTML/CSS

Anomali

Contract gig, permanent impact.

Jumped in as a contractor to help ship a new corporate site. Turned loose HTML/CSS/JS into a tight system of reusable modules, then built custom sorting and filtering components that actually made dense data navigable.

  • JavaScript
  • HTML/CSS
  • UI Components

Caringo

The bridge role.

Sat between design and engineering, translating mockups into production UI. Built a reusable module library that sped up interface development across the product suite.

  • HTML/CSS
  • UX
  • Component Systems

BuildASign

E-commerce at speed.

Worked across the full front-end stack -- product pages, new site launches, and high-volume marketing emails. Helped ship EasyCanvasPrints.com alongside the core BuildASign platform.

  • HTML/CSS
  • Email
  • E-commerce

A Bit About Me

I'm a front-end developer who cares way too much about the details. The pixel that's off by one? I see it. The hover state that feels sluggish? It bothers me.

I've spent 15+ years in the space between design and code — the handoff zone where good ideas either survive or get flattened. My job is to make sure they survive. I build interfaces that feel considered, not just functional.

I've done this across e-commerce, cybersecurity, big data, nonprofits, and agencies. Different problems, same standard.
