I need an extra pair of hands inside a mixed Linux/UNIX test environment where I’m already handling user management, permission tuning and routine maintenance. The immediate help I’m after centres on three areas: – Server oversight: keep an eye on CPU, memory and disk usage through top, restart or stop services with systemctl, and schedule housekeeping jobs via cron. – Log–driven troubleshooting: application logs are our main early-warning system, so you’ll be grepping, tailing and cross-checking them against system events to spot anomalies before they escalate. – Database sanity: everything runs on MySQL; I’ll pass you structured tasks that range from quick CRUD fixes to writing more complex joins and sub-queries for internal reports. Performance and readability of each statement matter just as much as correctness. SSH access and a Bash-heavy toolkit are already in place—df, du, grep, and friends—so you can dive in without fuss. I’m looking for concise status notes after each session and will test SQL changes in our staging schema before we move anything to production. If you’re comfortable hopping between shell and SQL prompt and can diagnose issues based on real-time metrics and log patterns, this should be straightforward and rewarding work.
