K90, Inc. (Dallas, Texas)

Designed and implemented the ISP side. This included installing Open Source mail, web, DNS, and FTP. Designed a large template based bash shell scripting system to help keep management simplified and centralized. Continuing management of ISP side.

Manage networks of K90 clients (firewall, security, remote access, VPN). Periodic end user support for K90 clients. Periodic Lotus Notes programming (in LotusScript).

Current project includes upgrade path of ISP to virtual servers for security and ease of management.

Developing and continually enhancing a Linux based firewall based on Open Source / GPL'd software.

    Features include:
  • QoS bandwidth management and connection balancing
  • OpenVPN (also encrypted tunnels using SSH)
  • self monitoring and repair (using mon to automatically fix predictable problems and warn of others)
  • auto upgrade package retrieval and install (my over sized shell script that fetches through an encrypted tunnel)
  • internal SMTP relay out (using qmail, handy for small offices to not rely on their ISP)
  • internal DNS (handy for small offices to not rely on their ISP)
  • internal DHCP server (with Dynamic DNS update)
  • internal NTP (Network Time Protocol)
  • HTTPS web reporting from MRTG (various system stats, interface traffic, and firewall drop log)
  • firewall high availability (heartbeat and a hot stand-by)
  • server clustering and high availability behind the firewall (using Linux Virtual Server, LVS)
  • active Network Intrusion Detection blocking (using Snort and a light weight program I wrote)
  • simple porn site filtering (using Snort and that light weight program I wrote)

This firewall can also be configured as a network bridge with basic firewalling and QoS. This is essentially an invisible firewall capable of being inserted into network setups where topology changes would be difficult or inappropriate.

Advanced level network design, implementation, integration, clustering, load balancing, back up, and security at K90 and for our clients. Software experience includes: Linux Firewall (iptables), Linux High Availability (HA) and Load Balancing (LB) Clusters, Linux Network Bandwidth Management (Quality of Service, QoS), Linux OS Hardening, Linux Self Monitoring and Recovery (using mon), Linux Virtual Private Networking (VPN using OpenVPN, also encryption tunnels using SSH), Linux Intrusion Detection System (IDS, Snort), BIND 9.x (DNS), qMail SMTP, Apache Web Services, SILC Server (fully encrypted Instant Messaging), Network Time Protocol (NTP), Andrew File System (AFS), SAMBA File System (SMB), Network Monitoring (Nagios), Network Reporting (MRTG), file system Logical Volume Manager (LVM), Network Backup, osCommerce E-Commerce Package server side, and Lotus Notes server side. Also responsible for software development and new software research, evaluation, and testing.

As a support specialist, I would typically take 8-12 trouble shooting calls per day for diversified network setups.

This position also required clear oral and written communications skills.
