Description

I build AI solutions for companies that don't want to get stuck at the next PowerPoint presentation.

I wrote my first code at the age of 6, and have been a professional software architect since 2014. C#/.NET, Azure, Cloud-Native, complex systems. By day, I lead a development team; by night, I wonder why so many companies do manually what an LLM integration can do in hours.

My focus:

- LLM integration into existing systems (.NET, Azure, APIs)

- RAG systems for internal documentation and knowledge management

- AI agents and multi-agent architectures

- Software architecture for scalable AI applications

- Sparring and reviews for ongoing AI projects

My approach: Pragmatic AI strategy instead of PowerPoint battles. Every company needs a foundation, but start small instead of a 6-month concept. First, understand and prioritize the use case, then design the architecture, then build and deliver the solution. Strategy and implementation go hand in hand.

I work exclusively remotely. Available during German business hours, languages German (native) and English (fluent).

If you have an AI pilot that isn't going into production, or are looking for a concrete idea for AI in your company, let's talk.

At The NextGen, I was employed as a staff member and seconded to various projects. The following projects during the same period as my employment at The NextGen were implemented as client projects by The NextGen. I transitioned to Tricept Informationssysteme GmbH during the project phase as a permanent employee to subsequently take on management roles. This opportunity was not possible due to the project work at The NextGen, so I took this step after careful consideration.

October 2021 - March 2022 (5 months)
Hannover, Germany
Scanblue Engineering AG offers solutions for the fully automated creation of 3D models from physically real objects. To this end, it offers customers the placement of a 3D scanner within the customer's own premises. The customer only needs to place the object to be scanned on the base, the scanner does the rest. Afterwards, the model can be post-processed online and used in online shops or AR/VR solutions.

My primary role at Scanblue is to advise on the setup of the new "Customer Cloud". This portal offers customers access to 3D models, marketing options, and further information. I primarily support the cloud and microservice architecture and its implementation.

I implemented a feature for calculating statistics. These statistics include the number of views of individual 3D models and break down the incurred costs by model and month. This is particularly important for customers who, in turn, have multiple customers themselves. This allows costs to be passed on precisely and transparently for the actual views incurred.
