Two decades of infrastructure that had to work.

Who you are hiring

Twenty years in the trenches, not on a slide.

Ronald Méndez has spent more than twenty years in systems administration and network engineering — enterprise environments, public sector, and small businesses where the person who designs the network is also the person who answers the phone when it breaks.

That background shapes how this practice works. Networks get documented while they are being built, not afterwards. Backups get restore-tested. Changes get a rollback path before they go live. And when something is fragile, you hear it plainly rather than in a slide deck.

505 Networks exists because a lot of small and mid-sized organizations are paying enterprise prices for work that does not need an enterprise, and getting enterprise process in return for problems that a competent engineer could simply fix.
