During this project great improvements have been introduced into my server network and infrastructure. The system became more stable, secure, easier to maintain and monitor and I also learned a lot about system administration myself because all procedures and changes were well documented. I would definitely recommend this freelancer and plan to cooperate with him more in future. [10 July, 2018] All tasks were finished efficiently, on time and on budget. I would definately recommend this freelancer. [15 July, 2018] Great job setting up database backup and recovery system for my server. [07 August, 2018] He helped me find and implement an excellent monitoring system for my servers and showed me how to use it with great professionalism. I will keep working with him again. [12 August, 2018] Some improvements of the existing database backup scripts have been made and they work even better now. [28 August, 2018] The Python version of database backup and restore script he wrote for me works great and the code is very clean and easy to debug. I will go on working with him on other projects. [10 September, 2018] A script to do the database copy on Centos 7 has been made very quickly and efficiently. [17 October, 2018] He provided me with great instructions on using Redmine project management system. I would definitely recommend this freelancer. [09 November, 2018] He made a database copy script which has an ability to copy the data from one database to another on the same server, export the database to an archive and import it into another database on the same or report server. The script was working perfectly and without any errors. [19 November, 2018] He helped me set up Gitlab system and better understand how version control works and how could it be applied in my company. [09 December, 2018] Updates he applied and suggested on Redmine, Zabbix and Gitlab systems made my company's infrastructure much more secure and easier to monitor. [23 December, 2018] He provided a great help in automatic SSL certificate renewal setup and solving issues with AutoSSL problems on CPanel server. [28 December, 2018] He helped me set up antivirus protection for all my servers and code version control. My system is much more secure and easy to maintain now.
