Why ThatDeveloperGuy

Most studios stop at SEO. We deliver the full engine optimization stack.

SEO is one engine. Now there are four. Google, the answer engines (ChatGPT, Claude, Gemini, Perplexity), Google AI Overviews, and generative engines (Bing Chat, You.com, Brave). Each ranks differently. We build for all of them in one engagement, with a free written audit before you spend a dollar.

Common questions

Pre-empting the "but what about" questions.

Hand coded custom websites and full stack engine optimization (SEO, AEO, AIO, GEO) for small businesses nationwide. Founded 2017, SDVOSB certified, based in Cassville Missouri. Over 130 production sites deployed since 2020 across owned infrastructure.
Two reasons. One: the audit is a sales tool that's also a deliverable. If you don't engage, you walk with a useful document. Two: most studios bill discovery as "strategy" and pad the timeline. Our audit replaces that, costs us a few hours, and means we never start a build we can't move the needle on.
Traditional SEO targets Google's blue links. Engine optimization is the full stack: SEO (Google, Bing), AEO (ChatGPT, Claude, Gemini, Perplexity), AIO (Google AI Overviews), GEO (generative engines). Each ranks differently. Sites optimized only for traditional SEO are bleeding traffic to AI engines that won't cite them. We build for all four in one engagement.
SDVOSB = Service Disabled Veteran Owned Small Business, certified through the U.S. Small Business Administration. For federal contracts and prime contractors, SDVOSB status corresponds to actual SDVOSB labor. Our SDVOSB subcontract participation survives DCAA audit because the founder does the actual work. For non-federal, it signals founder operated, no pass-through, accountability lives in one chair.
Single landing page: 7 days. Multi-page small business site: 7 to 14 days. Federal scopes with Section 508 remediation: 30 to 60 days. We send a working demo at a temporary subdomain before any payment so you see the actual finished site rendered with your content, not a Figma file.
Hand coded HTML, CSS, and vanilla JavaScript on most builds. Fastest possible Core Web Vitals, easiest to maintain, no framework rot. Astro or Next.js when the project actually needs a framework. All sites self hosted on owned infrastructure in the United States (Debian + nginx). No Cloudflare, no third party CDNs, no Wix or Squarespace.
Yes. The monthly $397 engine optimization program includes weekly AI citation polling across ChatGPT, Claude, Gemini, and Perplexity for a defined set of branded and category queries. You see in the monthly report which AI engines now cite your site, and which queries still don't.
Most common scenario. The free audit covers what's recoverable on the existing site (schema upgrades, content depth pushes, GBP linkage) vs what only a rebuild solves (frame­work migration off Wix/Squarespace, Core Web Vitals stuck below threshold, broken site architecture). You get a clear recommendation either way.
Square Invoice for credit cards and ACH. Net-15 terms available for engagements over $5K. Government contracts via SAM.gov registration accept the standard federal payment workflow. No PayPal, no Zelle, no crypto.
