For general inquiries, detailed questions or longer explanations,
e-mail is usually the best choice.
I read every message carefully and reply personally.
Threema
If you prefer secure and private communication,
you can reach me via Threema.
Ideal for short questions or sensitive topics.
Upwork
For project-based work, proposals or formal collaboration,
you can also contact me via Upwork.
This is the best option for structured project requests.
