Technology Lead CAD — LogiKal

https://orgadata.com
For many years, I owned the design, implementation, and other aspects of the CAD, 2D, and 3D components of the global market-leading software solution, LogiKal.
Primarily with metal workers as users, this software brings planning, simulation, and machining capabilities. It also allows seamless integration into Autodesk Revit and AutoCAD.
During this time, I was the technology and team lead for the respective team(s).

API for Intralogistics

I designed, built, and maintained an API that connects a fleet of smart devices (drivable) with their renter. This API has been a pioneer project in the intralogistics branch and is now considered a key element in companies' roadmap and plans. During the project, I created a patent for IoT device communication in context with cloud-based automation.

eCommerce China Expansion

I was the technical lead for expanding one of Europes biggest eCommerce companies into the Chinese market. Within that project, I connected the IT systems based in Germany and Europe with the newly built systems in China to be able to process orders. This project featured on-site work in China, integration for SAP and other Europe-based systems as well as logistics, and much more.

3D Construction Software for Architects

The project consisted of standalone 3D construction software, also available as an add-on for Autodesk Revit, making it especially easy to design curtain walls, windows, doors, and other construction elements. Including a seamless integration into Autodesk Revit and the proprietary software LogiKal, which is the global market leader, the process of design to construction is much more efficient for our clients.

Apollon

A solution that analyzes tickets to derive a meaningful priority, assignable components, and other additional information only from the title and description. It pre-organizes tickets and adds some more information to them to ease the respective product owner's work.

I performed the data mining on AWS with Python and the deep learning implementation with Python and PyTorch.

complate

https://replicadse.github.io/complate
"complate" is an open-source in-terminal text templating solution that I built to replace variables with data interactively.
Its primary use case has been templating GIT commit messages according to a custom-defined standard. Still, it can serve many more applications, such as configuration file generation or even code generation.

Hydrogen

Rust-powered, fully open source, Kubernetes native WebSocket API Gateway.
Used for abstracting WebSocket connections from downstream services and translating messages into HTTP calls, including retries, circuit breakers, and more.
