Infrastructure & Networking

Good application code sitting on a poorly configured server is still a liability. This covers the infrastructure layer underneath everything else — servers, networking, and the environments that keep development from breaking production.

What this includes

  • Production Linux (Debian/Ubuntu) server administration
  • Multi-tier Live/Test/Dev environments connected over OpenVPN
  • Apache & VirtualHost routing and configuration
  • Firewall and network security for servers, workstations, and the organization as a whole
  • Performance upgrades matched to where the actual bottleneck is — hardware, database tuning, or architecture

This is LPIC-1 certified practice, not ad hoc server administration — six-plus years of keeping production Linux environments stable for organizations of every size. One concrete example: an SSD migration that cut a client's heavy report runtimes by an hour, diagnosed as a hardware bottleneck rather than something that needed a code rewrite.

The same multi-tier Live/Test/Dev discipline used internally is available as part of any engagement, so changes get tested somewhere that isn't the production server people actually depend on.

Not sure this is the right fit?

Every engagement is scoped individually — reach out and we'll figure out what actually fits.
