A software studio in Scottsdale. One person you can actually call.
DevPlus is run by Isaac Riehm. The studio builds custom internal software, automation, and websites for businesses that have outgrown spreadsheets and off-the-shelf tools — mostly owner-run service companies, many of them in healthcare and billing.
Every engagement runs the same way: a call, a short look at the real workflow, a fixed price with milestones, working software every week, and a handoff where you own the code, the hosting, and the data.
I bring in specialists from a small network when a project calls for it, and I build with modern AI tooling — which is how a one-person studio ships systems that used to take a team, without the team’s overhead or the agency’s handoffs.

Questions owners ask
- Is it really just you?
- Yes — and that’s the point. The person you call is the person who scopes the work, writes the code, and answers afterward. When a project needs a specialist, I bring one in from a small network, but nothing gets handed off behind your back.
- What do you build with?
- Boring-in-a-good-way tools that will still be maintained in ten years: TypeScript, React and Next.js, PostgreSQL, and the integrations your business already lives in — QuickBooks, spreadsheets, email. I work with modern AI tooling too, which is how one person ships what used to take a team. Either way, you own the code.
- What does a project cost?
- There’s no price list, because the honest answer depends on the workflow. What you get instead: a short look at how the work actually runs, then a written fixed price with milestones — before anything starts. Small, fast jobs are welcome when they fit.
- Where do you work?
- Scottsdale, Arizona. On-site around the Phoenix metro when it helps; remote for everyone else — most projects run fine over a screen-share and a phone line.
- Can you sign a BAA?
- Yes. Where an engagement involves protected health information, DevPlus works under a signed Business Associate Agreement with the safeguards the work requires.
