    This is your new go-to server guy! Dealing with Linux, Web servers, VPNs, monitoring your systems, being your own System Administrator / Network guy is what I do for a living. Be it fixing your email problems, editing your SPF/DKIM records, speed-optimizing your system, configuring your Nginx or DNS server, working with your programmers to roll upgrades on your systems, installing and configuring anti-spam/email solutions, announcing an IP address, setting up a dedicated server and installing a virtualization system on top of it, setting up a VPN server to being that person you need to ask your "techy" questions, I'm here for you. On a daily basis, I usually deal with providing consulting services, managing whole networks, Cloud Engineering on AWS / GCP and Azure platforms as well as handling lots of dedicated servers for various professional needs. What I usually do are listed below - Installing / Upgrading your system and scripts This is what I usually deal with on a daily basis. - Setting up your servers, RAID, ESXi, Proxmox etc. I personally run a dedicated server/mail / antispam business. - OS and Application level Linux Administration. / DevOPS I currently have clients that I look after. I usually keep their systems up-to-date, roll new releases of their software on the system, configure their servers, monitor their servers and whatever else they need. - Network Administration Although it is not my strong suit, I personally run my own ASN using Bird and Mikrotik announcing my own IPs through anycast BGP for my own use as well as client machines and VMs. - Mail Administration As I provide Mail services AND Anti-Spam Gateways, I do know a bit about what gets delivered, what gets stuck and I can try my best to work it for your needs as well. - DNS Server Administration I run various Bind and PowerDNS nodes for Geo DNS purposes. This includes Reverse DNS servers as well as your regular domain.com servers. - Monitoring Systems Zabbix / Smoking and such are the usual tools that I frequently use to run my businesses smoothly. - Plesk / cPanel / LAMP / DirectAdmin Are some panels I use for business, used or installed. What I know or do is not limited to what's listed above. I am willing to learn new stuff and work towards a common goal as long as we can communicate our needs and requirements from the start and thank you btw for reading these lines as most usually tend to skim the text and move to the next person. I can tell you here that even if you didn't see what you are looking for, chances are that I already know about it. Just try asking me or inviting first. As I already have a company of my own, some of my time is already sold out. We can discuss it in detail when you tell me what exactly you want to do, what do you expect me to do and such. I strongly believe that we can find a way to do what you need to be done.
