Skills

Cruziero's professional skills lie mainly in the following areas:

Servers -
email (sendmail, dovecot, opensmtpd, postfix), dns (bind, unbound), web (apache, openbsd httpd/relayd), network-accessible data storage, calendar/contacts.

Security -
cryptography (pkc/certificates/..), intrusion detection (e.g. tripwire), firewall (e.g. iptables), scanning (e.g. nmap), log-file analysis & response, forensics, anti-virus/spam/malware.

Computer Programming -
standalone, network and web-based applications running mainly on UNIX/Linux/BSD; accessible (for network/web) by any device (windows/mac/android/linux/bsd/...). Mostly we use the various UNIX/Linux/BSD shells & utilities, C, and, to a lesser extent, Python, Perl, and JavaScript.

Databases -
design, creation, population with data, querying, reports, .. . We use PostgreSQL/MariaDB/MySQL, bdb/lmdb/sqlite, *nix-shell-utils/C, and (for web-based applications) Python/Perl/PHP, for most solutions.

Automation -
each component of information should be sourced/written/specified once only and in only one place: and automated systems/programs then dice'n'slice/combine/transform/convert (a working-copy of) that data automatically into the wanted output formats; there should be no manual re-typing/re-formatting/re-obtaining/copy'n'paste/&c.

Operating Systems -
client & server: Linux (Slackware, Debian, Amazon; & similar), BSD (OpenBSD, FreeBSD), Plan 9; bare-metal & virtual (kvm/qemu/xen). Client-device connections-to-network/server: windows, mac, android.

IT Support & Management -
website (public[internet] & private[intranet]), email, domain, data, firewall, security, .. .
