Complex systems. Clear connections.
Secure software, APIs, and integrations for the systems in between.
MiddleSystems is a Kansas City–based consultancy that designs, builds, and secures the software that connects other software: REST APIs, middleware, and integrations between the systems a business already runs on.
- API & middleware development – REST services and integration layers that move data between systems reliably.
- Systems integration & migrations – mapping, tooling, and glue for moving between platforms without dropping anything on the floor.
- Secure SDLC & supply chain – pipeline hardening, dependency and vulnerability management, practical DevSecOps.
- Architecture – microservices designs that are as simple as the problem allows.
- Secure by default. Least privilege, reviewed changes, dependencies we can account for.
- Honest scoping. We'll say what we can do, what we can't, and what it will take.
- Documented handoffs. You should be able to run what we build without us.
Public repositories here are things we've chosen to share. Client work is private and stays that way.
