Capabilities

What I Build

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

Websites & Online Stores

WordPress, Shopify, and Next.js sites custom built that are fast, reliable, SEO optimized and easy for you to edit yourself.

Internal Tools & Automation

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

Integrations & AI Workflows

Connect the software you already use. APIs, MCPs, integrations, and AI where it saves time and resources.

Speed & Search (SEO/GEO)

Slow pages, junk code, and unused scripts cost real money. Fix speed, schema, and local search, including whether LLMs can find you at all.

About

Who I Am

I'm Jacob Cain, a developer and systems engineer in Cincinnati, Ohio. I enjoy building the things businesses actually need and improving the processes around them — a good system can make or break your success. I build e-commerce stores, restaurant sites, tooling, and internal apps customized to your business.

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

AI-assisted workflows on top of my background means I ship quickly without stepping outside the security and governance guardrails your business needs.

Based in Cincinnati, working with companies nationwide.
