Capabilities

What I Build

Websites, stores, and internal tools - built to be used.

Websites & Online Stores

WordPress, Shopify, and Next.js sites built from scratch - fast, findable, and easy for you to edit yourself.

Internal Tools & Automation

Dashboards, generators, and scripts that replace the spreadsheet-and-copy-paste work your team does every week.

Integrations & AI Workflows

I connect the tools you already use - APIs, MCPs, data syncs, and AI where it genuinely saves hours, not where it looks impressive.

Speed & Search (SEO/GEO)

Slow pages and invisible listings cost real money. I fix speed, schema, and local search - including whether AI tools can find you at all.

    Plan the system — platforms, integrations, and structure before any code is written.

  3. Build & Implementation

    Develop clean, maintainable software using the right tools and technologies.

  4. Launch & Improve

    Deploy, monitor, and continue improving the system as your business grows.

About

Who I Am

I'm Jacob Cain, a developer and systems engineer in Cincinnati, Ohio. I enjoy building things businesses actually needed and help improve the process, a good system can make or break your success. I build e-commerce stores, restaurant sites, tooling, and the internal apps customized to your needs or business.

I founded and ran my own Shopify retail brand for eight years, so I I know what it's like to depend on the tech and systems working.

Building with AI-assisted workflows on top of my professional background has made it so I can build quick, but with staying in the guardrails of your needs. Based in Cincinnati, working with companies all around.
