About

One person builds it. You can text him.

0arch is a one-person software studio that builds custom web apps, CRMs, and automations for small businesses. No account managers, no handoffs.

The name means zero architecture. I started with nothing behind it: no agency, no templates, no playbook. Everything on this site got built from a blank page.

Every project works the same way. We look at how you work today, sketch the system, you tell us what is right and what is off, then we build exactly that.

When you text, you get the person who builds your system. When you email after launch, same person. Nothing gets handed off, because there is no one to hand it to.

What gets built: custom web apps and internal tools, CRMs and client portals shaped around a real sales process, automations that move data between the software a business already pays for, and websites built to bring in the next booking. Most clients are small businesses and owner-run companies that have outgrown spreadsheets and off-the-shelf tools.

How it is priced: a fixed estimate for a written scope, no per-seat fees, and the code is yours at the end. Hosting runs on modern edge infrastructure for tens of dollars a month, and support after launch is optional, not a lock-in.

Here is what a project with 0arch usually looks like end to end. It starts with a text or a call describing what is not working, no signup form. We look at your current process and the software you already pay for, then sketch the system and walk through it with you before writing a line of code. You say what is right and what is off, then we build exactly that, with a fixed estimate for the scope in writing. You see a working first milestone before the rest of the build starts, so a wrong turn gets caught early, not at the end. Ten-plus systems built this way are still in daily use, some for clients who called years ago. If one of them breaks, you text the person who built it, not a support queue.
