Measured.
Deliberate.
Craft.
Rehbein Software LLC is a boutique backend engineering studio. With over 20 years of experience in back-end web development, systems architecture, and B2B EDI, we work with small and medium businesses who need a partner — not a vendor — for consequential web software. Our aim is simple: help you succeed.
The Rehbein Method
Our process mirrors a pour-over ritual. Three phases, executed with care. It's slower than spinning up a template — and dramatically faster than rebuilding a year of accumulated technical debt.
Extraction
Discovery and requirement saturation. We map your domain, identify constraints, and surface the technical risks that will define the project — before a single line of code is written.
Roasting
The heavy lifting. Rapid prototyping followed by disciplined development, code reviews, automated testing, and architectural decisions documented as we go.
Serving
Deployment via CI/CD, hand-off of extensive documentation, and ongoing performance monitoring. We don't disappear at launch — we make sure the system stays healthy.
Operating
principles
Boring tech, sharp execution
We choose tools for longevity and community support, not novelty. The interesting work happens at the architectural seams, not in the framework wars.
Documentation is the deliverable
Code that no one else can extend is a liability. Every project ships with the architectural decisions written down — for your team, not just ours.
Cloud-native by default
Over a decade of AWS in production — EC2, Lambda, S3, RDS, and the supporting cast. Infrastructure-as-Code via CloudFormation means your environment is a file in the repo, not a memory in someone's head.
Small team, full ownership
We work on a limited number of engagements at a time. You talk to the people writing the code.
