Summary
👤
Senior🎓
Top SchoolTimo Horstschaefer is a CTO and co-founder with 11 years of engineering and research experience, currently building an AI-native share plan platform at Ledgy from Zurich. He bridges deep academic training in theoretical and mathematical physics (ETH Zürich, KTH) with hands-on systems work spanning embedded event-camera SLAM research and full-stack product engineering. His open-source contributions range from low-level ROS drivers and fixed-point timestamping for DAVIS sensors to UX-focused enhancements in a performant React spreadsheet, showing fluency across embedded, backend and frontend domains. Known for turning advanced sensor research into robust code, he combines startup leadership with a practitioner’s attention to performance and edge-case correctness.

ROS packages for DVS
Role in this project:
Embedded Systems Engineer
Embedded Systems EngineerContributions:18 commits, 6 PRs, 27 pushes in 1 year 6 months
Contributions summary:Timo primarily contributes to the `davis_ros_driver` package, modifying the driver to interact with the DAVIS sensor. The changes include adding the `base_link` frame for the IMU, converting IMU data from NED to ROS ENU frame, and adding a parameter to control the maximum number of events. Furthermore, the user made improvements to the renderer for the event-only mode and implemented fixed-point arithmetic for time stamps within the ROS driver.

Simple, customizable yet performant spreadsheet for React
Role in this project:Front-end Developer
Front-end DeveloperContributions:16 commits, 6 PRs, 5 comments in 17 days
Contributions summary:Timo primarily focused on enhancing the user interface and functionality of the React-based spreadsheet. They implemented features like clipboard integration (copy, paste, cut), and integrated the `className` attribute to the `Cell` component for custom styling. Further, the user refactored and optimized the code, addressing edge cases in the paste functionality and adding unit tests to ensure proper functioning. The user's contributions are central to improving the spreadsheet's user experience and overall usability.
