Most teams split this work across four people. I do all of it.

I introduce myself to a client as a technical consultant, a partner, and an advocate, not a know-it-all. Most clients arrive with a frustration from a past vendor or project, so I ask about it first. That turns the conversation toward fixing their problem and builds trust faster than any pitch.

As the final escalation tier, I usually meet a customer after something has already failed. I explain the problem and the fix in plain language, stay with it until it is closed, and tell the customer what I changed.

My working rule is that if someone else can do it, I can learn to do it too. My degree is in music, not engineering. I started my own Crestron service-provider business, put a FortiGate on my own network to learn Fortinet, and built two AI demonstrations to learn how AI infrastructure fits together.

Music shows up in my technical work. I learned signal flow and gain structure behind a mixing console, so I can usually hear what kind of fault a room has before I open the digital signal processor (DSP). Playing in time with other musicians makes me notice delay, which is much of what networked audio and video design is about. And a live show is good practice for escalation work, because the fix happens while the audience is listening.

I also have a heart for helping churches with their sound and other technology. Most church tech teams are volunteers who have never been trained on the systems they run every week, so I explain the technical side in plain terms they can use to run the next service with confidence.

Each role has its own section, because each hiring manager looks for different evidence. Where I have done the job, the section shows the record. Where I have not held the role yet, it shows how I would do it, built on the same 25 years of networked systems work. Go straight to the one that matches your opening.
