Cloud WiFi and Captive Portal Specialist. 20000+ WiFi devices deployed
$50.00/hr
End-to-end Cloud Wi-Fi network and Captive Portal specialist, driven by a passion for pushing the boundaries of networking technology.
I specialize in crafting innovative, custom-built cloud-controlled Wi-Fi solutions, leveraging OpenWRT firmware on Atheros/MediaTek based routers, a robust LAMP stack on the cloud controller, and FreeRADIUS for seamless user accounting and session control.
While my expertise lies in building bespoke systems with custom Wi-Fi routers, I have also deployed large networks using vendors like Ruckus, Meraki, MikroTik, Ubiquiti, and others. These solutions power 23 successful Wi-Fi network brands across 18 countries, connecting over 2.5 million users every month.
