Home Network Security Overhaul

My home network has been compromised. I need an expert to:

- Diagnose security breaches
- Identify and remove unauthorized devices
- Secure my Wi-Fi and connected devices
- Provide guidance on protecting myself from future attacks

Ideal Skills & Experience:
- Strong background in cybersecurity
- Experience with home network security
- Ability to explain technical concepts clearly
- Trustworthiness and professionalism

Please help me regain control of my digital life. I do suspect that the individual may have used something like apple buisness or cisco technologies to gain complete access and control over everything I do on a daily basis. Including revoking my access to my own information. I need someone who can look beyond the curtain and really understand that it is not just the devices but all of the programs being used that most people do not even know exist. I need someone that is smarter than him in the technology world. He is the best I have seen in real life and unfortunately he had way too much access for way too long to deeply tangle me into this web before I even realized and now that I have been trying to get someone to listen I fear that I just mostly sound crazy. I know the right person with extensive knowledge and a passion for technology will know right away that I am anything but crazy. A true tech will know that if anything I probably didn't sound crazy enough. I do not feel that I have been able to have a private thought or conversation in over a year. I want my life back. HELP.
