RSC-Informatik

RSC-Informatik is a specialized IT service provider offering tailored solutions for businesses and private clients, and teams of all sizes. While we are a small company, we leverage a robust network of experienced IT professionals and partner organizations to deliver scalable and effective results. Our expertise includes develop state of the art Apps for iOS and Android, implementing automated trading strategies, and integrating APIs into client systems to enhance their operational efficiency.

Beyond software development, RSC-Informatik excels in scientific problem-solving, something that in our view has gone a bit missing over the last ten or twenty years or so… However, we carried the scientific method over to the 21st century, as we consider it still THE fundamental principle to solve any kind of challenge.

And let's face it, IT projects often get stuck and the requirements suddenly seem blurry and the motivation and focus of the team derails. We saw this so many times that we decided to give our solution a name: "IT SWAT Services".It was about time this baby got a name!You need it when you are lost and don't really know what's going on. We assist you (or even temporarily "take-over") the assessment of the situation, making sure the mission is clear and has market-fit and analyse "what goes wrong". Next we define the needed follow-up steps to resolve the critical challenges, eliminate "waste" and ensure the project gets back on the right path to success.
This all the while, with a clear focus on quality, commitment, and budget and based on the latest tech and industry standards.

On a more practical IT-OPs level, we got years of hands-on, low-level experience in setting up and running "legacy" backend systems running Linux. And then the same IT-Ops shabang in the Cloud, on AWS and GCP.

Recent Projects

We produce software all the time and most of it has to happen behind closed doors, as the code belongs to our clients and is not open source. But all the while, we can give an overview of selected projects here without revealing too many project internals or proprietary source code.
Since all software development depends on more software components that are foundational, we also contribute to that "body of work" of open source software, whenever we see components fit for wider-spread reuse and once the components are polished enough and easy to apply by others.
Below you find a short selection of recent projects and some cornerstone datapoints to each.

"Gemma Controller" - iOS/Android App

Gemma App: Loading Screen Gemma App: Device Control Screen Gemma App: Connect Device Screen Gemma App: Settings Screen
The company "Gemma design" hand-crafts beautiful furniture with integrated lights. The "Gemma App" connects and controls those lights over the Wi-Fi.
Best to have a look at the Website of Gemma design and maybe buy your own piece.

Check out the App on the Apple App Store! While you won't get to see the full range of the app without a corresponding lamp, you will still see a lot of the functionality, especially the settings and the HTTP Wifi Lookup on the "Connect Device" Screen.
  • Languages: Dart, Flutter, C/C++ (Arduino)
  • Features, available for fast future reuse in other Apps:
    • Scans for devices on the local Wi-Fi HTTP
    • Device state and datastreams handled "Reactive-ly" (Rx)
    • Stores preferences on local device
    • Dynamic Settings by configuration
    • All dialogs wrapped in abstracted, (still) closed library
    • Multilingual
    • Communication with Arduino Firmware over HTTP/JSON protocol
    • Location permission handling on iOS and Android
    • Integrated WebViews and external Links
    • Haptic Feedback
    • Sentry.io integration for Crash Report Analysis
  • Status: Published on the Apple App Store
Note: The Android App is ready but is not yet published for download yet. Soon to come after the last Gradle Build issues are fixed…

"SSID Resolver" - Flutter Library

SSID Resolver: Unknown SSID, Location Permissions Missing SSID Resolver: Request User Permissions SSID Resolver: Permissions Granted SSID Resolver: SSID Resolved
A Flutter plugin to resolve the SSID of the connected WiFi network. It gets the Wi-Fi name of the connected network.
The native code handles the interaction with different permission layers, especially the "Location Services" that have to be granted by the user. This interaction takes away the focus of the App and that requires handling the "re-entry event" with proper thread handling.
  • Languages: Swift, Kotlin, Dart
  • Features:
    • Very easy integration into client code
    • Mixin support with single method override
    • The code base for this package is fully open-sourced and can be found on github.com
  • Status: Published on pub.dev
Flutter is a Google framework that let's developers implement mobile Apps for Android and iOS with a single codebase. However when it comes to more low-level tasks, that involve the specifics of the underlying operating system, you still need to implement these solutions in native Swift (iOS) or/and Kotlin (Android).
Flutter plugins usually combine such efforts by providing implementations for both, iOS and Android operating systems and offering a unified access morphology through a single API.
