WifiMask VPN is a fast VPN and ad/malware blocker.
Creating WifiMask VPN involved building the Linux server based infrastructure, iOS & macOS app development, front-end & back-end web development. Through building WifiMask VPN I obtained in-depth knowledge of many different technologies including cryptography, app development, security, fire-walling, load-balancing/failover, automation, monitoring, alerting, logging, webservers, databases, networking and frontend & backend web development.
