Websites for the businesses that keep this corridor running.

Four Hundred designs, builds, and takes care of websites for local businesses along the 400, from Sandy Springs to Dahlonega. One experienced developer, start to finish. No account managers, no offshore handoff.

Real sites, built and looked after by hand.

Recent projects are added here as they launch — real businesses, real sites, no stock templates.

A straight road, not a maze.

  1. Mile 1

    Discovery

    We talk through your business, your customers, and what the site actually needs to do. No jargon, no discovery decks.

  2. Mile 2

    Design

    You’ll see real layouts early, in plain language, with room to react before anything gets built.

  3. Mile 3

    Build

    Your site gets built by hand: fast, clean, and made to work on every device your customers actually use.

  4. Mile 4

    Launch & care

    We launch together, then keep the site running: updates, backups, and a real person to call when something changes.

Two ways we work together.

01

Design & development

A new site, or a rebuild of one that's holding you back. Every page is designed and coded by hand around your services, your customers, and how people actually find local businesses like yours.

  • Custom design, never a template
  • Mobile-first, built for speed
  • Structured to be found in local search
  • Copy and content help where you need it

Ongoing care

Launch day isn't the finish line. Care plans keep your site fast, secure, and current, so nothing quietly goes stale after the invoice is paid.

  • Security and software updates
  • Regular backups
  • Small content changes, handled for you
  • Direct line to the person who built it

You work directly with me — not a team, not a ticket queue.

Four Hundred is run by Kevin Kozee, a web developer with over 15 years of experience. When you call or send a message, you're talking to the person who actually designs, builds, and maintains your site, start to finish and beyond.

No account manager relaying requests to an offshore team, no agency turnover. If something needs to change six months from now, you're reaching the same person who built it the first time.

Kevin lives right here in Cumming with his wife and two kids. Four Hundred isn't a side gig; it's a local business built to stick around.

Headshot to be added before launch.

Tell me about your business.

A few details now saves back-and-forth later. I read every message myself and reply within one business day.
