Developer from Germany 🇩🇪 with a focus on embedded systems, security research, and backend development.
Languages: German (native) · English (fluent)
I'm a hands-on developer working across multiple projects—some public on GitHub, others private or in collaboration. I work mainly with Kotlin, Python, and C, with a focus on ESP32 development, SDR radio, and Wi-Fi security tools.
Currently expanding into C/C++ for Windows UI and low-level programming, as well as Rust.
I value collaboration, open exchange of ideas, and continuous learning. As I'm actively developing my security knowledge, I welcome feedback, bug reports, and constructive input.
Always happy to connect—feel free to reach out for questions, collaboration opportunities, or just a chat.
What I work on:
Home server setups · Backend development with Python · Software-defined radio (SDR) · Wi-Fi security · Embedded systems · Flight simulation · Mobile & web applications
- C/C++ for Windows development and low-level programming
- Secure software architecture and design patterns
- Defensive security practices and project hardening
- Reverse engineering fundamentals
- Application development and design
