FAQ
What do I need to get started?
You just need a rough idea or project description. If you're using specific hardware (e.g. sensors, displays, modules), let me know the exact components.
Will the code be commented and easy to understand?
Yes! I always provide clean, well-structured, and fully commented code – in English or German, depending on your preference.
Do you only write code snippets or full projects?
I can do both! Whether you need a quick function or a complete working project.
Can you help fix or complete existing code?
Yes, I can debug and improve existing code or help you finish an ongoing project.
Can you add a web interface or GUI?
Yes! I can build simple web interfaces (ESPAsyncWebServer, SPIFFS, etc.) or Python GUIs (Tkinter, PyQt, etc.) to control or monitor your system.
Can you help me understand the code you deliver?
Yes! I always include comments and will answer your questions after delivery.
