I’m in love with Information Technologies, especially the ones who give life to the Internet. I always prefer to read, test, and investigate everything I can by myself instead of rely on expensive and long trainings. All major accomplishments in my career have been achieved that way. I firmly believe in: “everything can be done; we just need to find the right way to do it”, but I don’t lose my time in impossible or implausible tasks.

Areas of technical specialization:

• Linux and FreeBSD system administration, highly oriented to mission critical environments.
• Version control, continuous integration, and configuration management with git, redmine (gitolite integrated), jenkins, ansible and puppet.
• Servers and Services installation and configuration with automation tools and scripts (python, bash, ansible and puppet).
• Automated bare-metal/server infrastructure construction, including mirroring services for major linux distros (centos, debian, ubuntu, epel, elrepo, etc.), and preseed/kickstart templates construction for bare-metal automated linux installs.
• Small, medium and big technical infrastructures design, deployment and continuous improvement, oriented both to traditional I.T. and new cloud environments.
• Cloud computing deployments in OpenStack and AWS based clouds, both manual and automated with cloudformation.
• Container-based (docker) solutions, including clustered containers deployments.
• OpenStack clouds design, construction/deployment, administration and maintenance.
• CEPH Storage solutions for OpenStack.
• ISP services design, deployment, administration and maintenance, specifically for the following services and applications: DNS (bind, rbldnsd, dnsmasq), DHCP (isc), LDAP (openldap), SMTP (sendmail and postfix), POP3/IMAP (dovecot, courier-imap), Web Services (hosting and application portals – apache, nginx), AntiSpam/Antivirus (amavis, clamav, spamassassin, spf, dkim, dnsbl).
• Multi-layered/multi-server infrastructures design, construction/deployment and operation for mail, dns and authentication/directory (ldap) platforms.
• VoIP with Asterisk (PBX and Gateways construction). Dial-plan configuration with AEL asterisk language, and Asterisk load balancing with ipvs (piranhabased).
• Custom, highly available load balancers design and construction with Linux(piranha, basic-ipvs, haproxy).
• Advanced web proxy construction with squid, squidclamav, squidguard and cicap support.
• Clusterization of services with heartbeat, corosync/pacemaker, and drbd.
• MariaDB and PostgreSQL clustered solutions design and deployment.
• NAS construction with NFS, GlusterFS.
• Advanced monitoring for servers and services (snmp, mrtg, cacti, icinga, zabbix). Design and construction of clustered/highly-available monitoring solutions, with special-use monitored variables.
• Procedures and service detailed documentation on wiki or kb-based tools.
