21 Loopings

available for new projects

We solve problems with software.

Team of experienced engineers with decades of experience, building new ideas and tackling problems in many branches of the industry. Web apps, native mobile apps, data storage, cloud infrastructure and recently AI driven systems.

What we do

Tech buzzwords.

There's an application behind solutions to many real world problems. Customers usually want to know what technology we use to build them. Here are a few of them.

Fullstack web applications

From the database schema to the last pixel. Dashboards, customer portals, internal tools — we build them end to end and deploy them somewhere you control.

  • React
  • TypeScript
  • Node.js
  • Go
  • Springboot
  • Quarkus
  • PostgreSQL
  • MongoDB
  • DynamoDB

Mobile applications

Real native apps, not wrappers. We write iOS apps in Swift with UIKit or SwiftUI, and Android apps in Kotlin with Jetpack Compose. Your app will feel like it belongs on the phone.

  • iOS — UIKit & SwiftUI
  • Android — Jetpack Compose
  • Swift
  • Kotlin
  • ReactNative

Infrastructure

The plumbing your business relies on every day. We set up VPNs, Git hosting, CI/CD pipelines, deployments, be it Docker or Kubernetes clusters — sized for small and medium teams.

  • VPN
  • Git
  • CI/CD
  • Docker
  • Kubernetes
  • AWS
  • Self-hosting

How we work

As little management as necessary.

We minimize overhead, no customer happiness manager here, sorry. Here's what working with us looks like.

Step 01

We listen first

A short call about what you're trying to do. If we're the right fit, we'll say how we'd approach it. If we're not, we'll tell you that too.

Step 02

We build in the open

Shared repos, bi-weekly demos, running software from week one. You'll never have to wonder what we're doing with your money.

Step 03

We leave it maintainable

No lock-in, you own everything: the code, the infrastructure, the docs. We can support you long term or your team can run it all without us.

Who we are

We don't have one specialty.

Our work spans automotive, entertainment, insurance, finance, and internet — often with some of Germany's largest companies. We've also worked with small startups where one engineer wears five hats.

That variety means we've seen how the same architecture pattern fails in a regulated bank and thrives in a streaming startup. We use that perspective to ask better questions and make fewer assumptions.

“We're currently taking on new projects. If you have something to build — or something that is falling apart — we'd like to hear about it.”
