Development of the program

Hello. I am looking for a mentor in Linux. I have experience as a strong junior DevOps specialist, but Linux and Kubernetes are my weak points. While I have some project experience with Kubernetes, my interaction with Linux is very superficial. Creating something, adding, renaming, opening, etc. is clearly not enough. I need a mentor who can help me improve in this area. The main task is to ensure that the knowledge sticks in my head, possibly through some pet project, tasks, or something along those lines, rather than just "repeat after me." I have taken courses on my own, but they don't particularly "stick" in my head. Here is a rough list of what I think I need: - Linux/Unix systems — in-depth administration of operating systems, file systems, user and access rights management, processes and services (systemd), Bash scripting, logging, monitoring, security configuration, automation of administrative tasks; - Networking technologies — OSI model and TCP/IP stack, DNS, HTTP/HTTPS, SSL/TLS, SSH, VPN, load balancing, proxy servers, NAT, routing, network utilities (ping, traceroute, netstat, ss, tcpdump, curl), diagnosing and troubleshooting network issues; If Kubernetes can be added to this list, that would be great. Perhaps you can suggest something from your side. The format of the sessions, as I see it, is twice a week, meetings, discussions, consultations. More details can be your ideas and suggestions. Regarding the cost per hour or per month - please propose.

Unfortunately, during the website code update process (hereinafter referred to as deployment), there is a possibility of losing information from the database, i.e. deleting some records from individual tables. The idea of the database integrity control mechanism is to create a service called from the Admin Panel with two functions: 1. Record the state of the database immediately before deployment. 2. Control the correspondence of the database before and after deployment. The integrity of the database lies in the integrity of all tables in this database. The state of the table is defined by 1 parameter: "Number of records in the table". The table is considered intact after deployment if the state parameter of the table Before and After deployment matches. The full task description will be provided directly to the executor of the order. This is an interesting project at https://derzn.ru/drevo/, but it is a NON-COMMERCIAL project. The payment is symbolic in a sense. However, you will gain valuable experience in solving real, challenging tasks and receive good feedback for a job well done. You will enhance your portfolio and order history here.
