Fictional Company Network Design

I'm looking for a professional who can design a new network topology for a fictional company as part of a student task. The primary goal of this new design is to enhance the performance of the network.

Key Responsibilities:
- Design a mesh topology incorporating various network devices such as routers, switches, firewalls, wireless access points, VLAN, and subnetting.
- Document both physical and logical views of the network.
- Implement security measures within the network design.
- Ensure clear and effective communication of the design and its purpose to all 'staff' (this will be simulated communication).
- Use a diverse range of sources for network standards and topology information.

Ideal Skills:
- Strong understanding of network design and topology.
- Experience with mesh topology and the specified network devices.
- Ability to document and explain complex designs in a clear and comprehensible manner.
- Proficiency in German, as all communication and documentation needs to be in this language.

Please note, this is a fictional project intended for a student task.
Working language: German
