I’m fluent in working with Linux OS and open-source software, familiar with almost all variants of Linux distributions (especially CentOS, Debian, Fedora, Arch, Ubuntu) and software such as Apache, MySQL, Redis, Subversion, Squid, StrongSwan, Redmine, BIND, iptables, etc.) With more than 10 years in managing Windows network environment, beside Windows Server operating system, I'm knowledgeable in many of Microsoft technologies, e.g., Active Directory, Exchange, SharePoint, System Centers, Lync, ForeFront, MSSQL, etc. BASH and Python are the 2 languages that I can use very well in building tools and back-end programs/services. I'm also able to implement LetsEncrypt, a free solution for SSL. Its certificate request/renew could be done automatically or manually.
