Description

Network & Telecom Expert – Troubleshooting & Configuration (100% Remote)

With 8 years of experience in network and telecom infrastructure, I help VSEs, SMEs, and IT providers configure, secure, and stabilize their networks — without on-site intervention.

Experiencing unexplained internet outages? A VPN that drops? Degraded phone quality? I intervene remotely, quickly, with a clear scope and delivered results.

What I configure and resolve:

– Complete router configuration

– Secure VPN connections: remote access and site-to-site links

– WAN, NAT, firewall, and security rule configuration

– Network quality optimization for IP telephony (VoIP / Centrex)

– Diagnosis and resolution of outages, slowness, and instability

– Network audit and best practice recommendations

How I work:

100% remote intervention (access required via TeamViewer, AnyDesk, or SSH)

Fixed-price or short-term mission format depending on needs

Quick response, defined scope from the start, no surprises

Need a network that works, without you having to travel and without jargon? Contact me.
