Infrastructure check
For deciding whether moving your system to European providers pays off. Staying where you are can be the result, too.

Raimund Rolf Fleck, software architect and developer
I make your systems independent of US cloud providers without losing performance.
On servers from European providers of your choice: switchable at any time, and your data stays in the EU.
- In software development since 2017
- Almost five years of backend development on AWS and Kubernetes for a multi-tenant platform
- Two frameworks of my own for communication and data access in distributed systems

- PulseFramework for communication between servers
- SurgeFramework for data access
- Direct connection between client and simulation server while a player is in a room.
Services
I work on new systems as well as existing ones. The technology follows your system, not my own frameworks.
Cloud and infrastructure
I move systems from managed cloud services to servers at European providers and run them on Kubernetes. If you prefer, I also set systems up on AWS.
Cloud providers subject to US law can be required under the US CLOUD Act to hand over data to US authorities, even if it is stored in data centres in Europe. Where that rules a provider out for you, I set up the infrastructure with European providers.
Performance optimisation
I measure where your system loses time under load and remove the bottlenecks. The aim is the same load with fewer resources.
Software architecture
Modular monolith, distributed system, microservices or a combination: I design the architecture that grows with your demand and stays easy to change.
Backend development
Backends, APIs and integrations with external services such as payment providers, in C# with .NET or Java with Spring.
Security
I design security into the architecture from the start: isolated components, access control on every connection, vulnerability testing and data protection under the GDPR.
Starting offers
Each offer has a fixed scope and a defined result. After the intro call, I confirm scope and fixed price in writing before any work starts.
Performance and load analysis
For systems that slow down under load or are about to face more of it.

Architecture review
For new projects and grown systems, before major decisions are made.

Technical consultation
For one specific question or decision where a second expert opinion helps.

All prices are final. Under § 19 UStG (German VAT Act), I do not charge VAT.
Scope and process of each offerMy own projects
A real-time multiplayer game and the two frameworks it runs on, all designed and developed by me.
Real-time multiplayer game in development
Jump Jupiter
A rebuild of a 2009 browser game in Unity, running on a server architecture I designed. Release is planned for spring 2027.

Pulse
A call to another server looks like a function call in code. Pulse generates the code for it at compile time, and the transport can be swapped.

Surge
The same application code works with a single PostgreSQL server or with many distributed databases. Surge generates the access code at compile time.
More about SurgeHow I work
Direct contact
You talk to the person who designs and develops your system. There is no sales team or project management in between.
Your servers, your data
Servers, data and code belong to you, and you do not need me to keep the system running.
Performance as a design goal
How fast a system responds is decided in its architecture. That is why I plan for performance from the start instead of retrofitting it.
Traceable work
What I hand over is backed by tests, and every architecture decision is documented with its reason. That keeps your system understandable for your own team as well.
