The most amazing...
...thing I've coded was a cutting-edge medical imaging app for 3D computer tomography all running in real-time in a web browser.
Work Experience
Lead Engineer
Synphonyte
- Designed the UI and the architecture of a browser-based computer tomography application in Three.js and Vue.
- Built a proof of concept to see if it could be done performance-wise, proving feasible. Our app was even faster than many competing desktop apps.
- Grew a team around this app, and we kept adding features with a strong emphasis on UX and performance.
Full-stack Engineer
Self-employed
- Created a natural language processing back-end for a task management service in Node.js/Sails.
- Built an interactive image plotting service with real-time collaboration in Meteor and Angular.
- Designed and built a cryptocurrency price tracker with integrated real-time API.
Software Engineer
Südsicht
- Created a simple building game using Unity3D and C#.
- Developed an interactive product selection web app with complex data dependencies in Django and Python.
- Wrote an eCommerce payment plugin for a specific bank in PHP.
- Composed a simple knowledge base system with an extremely high focus on usability in Django and Python.
- Created a custom web-based ERP system in Python and Django with ODBC (Open Database Connectivity) integration.
Research Assistant
Fraunhofer Institute, Ettlingen
- Created a real-time person re-identification algorithm in C++ and OpenCV.
- Visualized research results in Python. I used this to write my master's thesis.
- Used OpenMP to parallelize and improve the performance of complex algorithms.
Experience
Student and Exam Management Software
Custom Web-based ERP System
Later, a stock tracking app was developed with Vue. I have been serving as the architect and lead developer for more than a decade. This is still actively used by customers.
Interactive 3D Product Viewer
iOS App for Automatic Size Estimation of Boxes from Images
Unity Painting Game
It is built in Unity, C#, and PlayMaker with a custom shader for the actual painting.
Real-time Ether Price Tracker
Medical/Dental Imaging App (Web-based)
I built a proof of concept to see if it could be done performance-wise, proving feasible. Our app was even faster than many competing desktop apps.
Then, I grew a team around this app, and we kept adding features with a strong emphasis on UX and performance.
High-performance Collaborative Drawing
