I need an experienced problem-solver to come to our facility near Mandurah (Perth, WA) and get a mixed stack of computers, networking gear and small-scale industrial machinery running smoothly together. The equipment is already on site; what’s missing is the hands-on expertise to trace every connection, configure the operating systems and application software, and then prove the whole setup works under real-world load. Here’s how the engagement will unfold: you’ll start with a quick walkthrough to map the current layout, note any gaps, and draft a step-by-step plan. From there you’ll move into configuration—tuning operating systems, aligning application settings, tightening network parameters—and finish with a full round of functional, performance and...
