Custom software development and integration
Custom software and the connections between the systems you already run. We build it small, test it and document it, so your team can run it day to day.
Web applications and APIs
Internal tools, customer portals and the APIs behind them, built on .NET, rendered on the server so they load fast, with accessibility built in.
Connecting the tools you already use
Most teams don't need another system. They need the ones they have to talk to each other. We build integrations with tools like ServiceNow, Jira, Confluence and PagerDuty, and with your own databases.
Sign in with your company account
Single sign-on through your identity provider, so there are no extra passwords to manage or forget.
Built to run without us
Small, tested pieces, a runbook and plain documentation, so your team can run it day to day.
Questions
What size of project do you take on?
Focused ones: a tool, an integration or a portal that a small team can design, build and launch in weeks to a few months.
What technology do you use?
Mostly .NET and C#, SQL Server, and modern web standards, chosen to fit what your team already runs.
Do you use AI in what you build?
Where it earns its place. Models suggest, tested code decides, and people stay in control.
What happens after launch?
You get a runbook and plain documentation, and ongoing support is available if you want it. McCallon Technologies keeps ownership of the code it writes; websites you buy from us are the exception and are yours outright.
