Felix Schaller
Systems Engineer & Software Architect
Experience
App Developer
XIXUM-Modeler
- Developing a model-based AI where natural language is interpreted as formal relations.
- Natural language terms are not considered rigid but fluid and can be negotiated in a context so meaning resolves by iteratively specifying.
- Develops all kinds of model solutions.
- Backed by natural language and data annotation.
- Requirements to code and other solutions.
Designer/Developer
Spes ML
- Developing model theory.
- Develop simulation concept.
- Meta model editor of exported MagicDraw UML diagrams for report generation.
- Interface between meta models and report generator.
Designer/Developer
NLX – Natural Language Platform
- Developed a DSL that can process natural language documents and transform them into a DOM model with Eclipse Modeling Framework (EMF) and XText.
- Backed with a Neo4J database to train grammar trees.
- Frontend application (GUI) developed with JavaFX.
- Published paper: “Machine trainable software models towards a cognitive thinking AI with the natural language processing platform NLX” DOI: 10.18420/modellierung2022ws-010.

Founder / Start-Up
AF-AX – Aeroflexible Aerodynamics
- Fluid dynamics spin-off technology with the goal of developing VTOL air taxis.
- Patented technology (EU WO 2012075990 A2, DE 10 2019 005 137 A1, DE 10 2014 004 990 A1).
- Idea was to mimic a bird's wing with feathers allowing passive dynamic reshaping of the wing profile by the surrounding air, leading to a better profile according to surrounding air: reduces stall on an airplane wing; reduces drag; increases lift.
- Can solve transitions of VTOL state from vertical to horizontal flight through stall reduction.
Computergraphics Developer & Visual Effects Designer
Self employed
- Developed computer graphic effects with computer graphics software like Autodesk Maya, Python, SideFx Houdini, Adobe Creative Cloud.
- Various projects in commercials and cinema movies.

Summary
My professional background spans multiple technical domains — including mechanical and aerospace engineering, computer graphics and vision, and AI- and NLP-driven software systems — connected by a consistent systems-engineering and model-based approach.
Across all roles, my focus has been on translating complex, real-world phenomena into explicit, formal models that can be analyzed, simulated, validated, and automated. This includes model-based system design in safety-critical automotive and aerospace contexts, semantic and knowledge-based modeling for language-driven AI systems, and physically grounded modeling in aerodynamics and simulation-heavy deep-tech environments.
I specialize in building structured representations that bridge domain knowledge and software systems, using technologies such as Python, Java, model-driven engineering frameworks, graph-based data structures, and modern AI/NLP tooling. This model-centric perspective allows me to work effectively across domains that, while diverse in subject matter, share a common need for rigor, abstraction, and traceable system behavior.
As a result, I am comfortable operating at the intersection of engineering, data, and AI, particularly in roles that require architectural thinking, cross-domain integration, and the ability to reason about complex systems beyond a single discipline.
