I solve your problems with UNIX systems (Linux, Solaris, Mac OS X, BSD), or I don't get paid.

Working on UNIX systems since 1998. Every one of my "real life" jobs so far has been UNIX-related.

Performance monitoring, optimization, security, automation, backups and disaster recovery, load balancing... you name it.
Service Description
What I can do for you:

- Secure your server(s)
- Optimize for performance
- Remote monitoring (service availability, resource usage)
- Configuration and periodic maintenance of the OS and services (web, mail, DNS, FTP, databases, etc)
- Install/upgrade software
- Writing and customizing scripts for system maintenance
- Setting up periodic backups of your server (including mail, web files, user accounts and databases)
- Others (just ask!)

I only work remotely. I upon acceptance of the work I will require SSH access to your system(s). If you don't know how to set it up then I will help you set it up.

We can communicate in English, Spanish, Catalan or Japanese.
