I've run the operations. Now I build the systems.

A business isn't its tech stack. It's the work, decisions, numbers, handoffs, habits, and incentives behind the software. Most companies don't need more tools. They need a clearer operating system.

I design high-performance operating systems for businesses. Software is one of my primary tools for implementing them. The others are process, data, incentives, and the people who have to live with all of it.

I come at this as an owner, not a vendor. I build and run production systems my own businesses depend on, so I design yours the way I design mine: to run for years without drama.

I'm Zac Ruiz, a Marine Corps veteran and JPMorgan alum who served as CTODirector of Technology & Strategic Growth of an EOS-run homebuilder doing ~130 homes per year. I've lived the L10s, Rocks, Scorecards, and the leadership meetings where everyone had different numbers.

Today I build custom operating systems for founders and operators whose businesses have outgrown spreadsheets, disconnected SaaS tools, and tribal knowledge. Dashboards, workflows, data pipelines, and mobile apps are the components. The real work is making the business easier to operate because the systems finally match how it actually runs.

I model before I automate. Most software projects fail because they automate a broken operating system. Before writing code, I want to know where information enters, where decisions happen, where handoffs break, where incentives conflict, and where the numbers stop being trusted. Only then should software be designed.

Sometimes the answer is a custom platform. Sometimes it's automation. Sometimes it's deleting software instead of adding more. The goal isn't more technology. It's a business that runs better.

Good software reinforces culture. Bad software creates workarounds, and a system people work around is already failing. A dashboard is only useful if it changes behavior.

Boring technology wins. I'd rather build something your team happily uses for ten years than impress another engineer for ten minutes. If you don't want to babysit your infrastructure, I'd argue that boring tools are a feature, not a compromise.

Real estate, construction, and the trades. Builders, agents, investors, property managers, lenders, and operators whose businesses run on relationships, timing, and field execution. I've been in the room, and I won't be learning your business on your dime.

These businesses usually share the same problem: the work is real, the revenue is real, but the systems are scattered. Spreadsheets multiply, data lives in five places, and key workflows depend on one person remembering what to do. That's not a software shortage. That's an operating system that hasn't caught up to the business.

Founders and operators who know their business deeply, feel the operational drag, and want a builder who understands the business model before touching the technology. If your team duplicates work across systems, nobody fully trusts the reporting, and you spend more time managing software than managing the business, we should talk.

I'm probably not the right fit if you're looking for the cheapest engineering resource, a pixel-for-pixel build from a fixed spec, or another advisor who produces strategy without implementation.
