Custom Web Applications
I'm Bill, a full-stack developer in Tucson, Arizona. When off-the-shelf software doesn't fit, I design and build custom web applications, from client portals and booking tools to internal dashboards and full SaaS products. I've built and launched several apps of my own, so I know what it takes to get one from idea to real users.
Every custom web app development project includes:
We map the workflow and the users first, then agree on a focused first version worth building.
React, Next.js and TypeScript on the front end; Node.js, PHP, Firebase, Supabase, PostgreSQL or MySQL behind it, chosen to fit the project.
Secure sign-in and role-based access so each person sees only what they should.
Stripe payments, calendars, email, SMS and API connections to the tools you already use.
Practical AI features such as drafting responses, summarizing records or routing requests, when they save real time.
Deployment, testing on phones and desktops, and ongoing improvements after launch.
We talk through your goals, your audience and what isn't working today. No cost and no obligation.
You get a written scope, timeline and fixed price before any work starts, so there are no surprise costs.
I design and build the site, sharing progress as I go. Three rounds of revisions are included.
I handle testing across phones, tablets and desktops, then launch and make sure search engines can find the new site.
30 days of post-launch support are included. After that, ongoing care is available hourly or on a monthly retainer.
Small, focused tools can start at $2,500. Larger applications are scoped with you and quoted as a fixed price before work begins, and mobile or cross-platform apps typically run $5,000 to $15,000. Milestone payments are available.

It depends on scope. A focused first version usually takes a few weeks to a couple of months. I'll give you a timeline with milestones during planning, and we'll launch a smaller first version sooner rather than wait on every feature.
Mostly React, Next.js and TypeScript, with Node.js or PHP on the server and databases such as PostgreSQL, MySQL, Firebase or Supabase. I choose the stack that fits the project and that you can maintain long-term.
Yes. Once the project is paid in full, the code and the accounts it runs on belong to you.
Yes. I build with AI tools like Claude and OpenAI and add AI features where they save real time, such as drafting replies, summarizing information or routing requests.
Often, yes. I'll review the existing code first and tell you honestly whether it's better to continue, refactor or rebuild.
