About us

We're CSA, a small studio in Perth, for local businesses and anyone with a project of their own. The letters stand for what we do.

  • CodeWebsites and online tools.
  • ShapeDesign, 3D and video.
  • AutomateSystems that save you time.
A short film, with no sound, of our studio built as a model and seen from the front with the roof off. The CSA sign hangs on the back wall between two desks. Someone stares at the kettle, gives up and turns away, and that's the moment it boils. The printer jams, cops a whack and fires its pages across the floor, and the last one floats down onto its owner's head. Someone wrestling a tangled extension lead yanks the wrong plug, the coder's screens go black, and the coder slowly swivels round to look at them. The designer spins in their chair until an idea lands and the desk lamp clicks on, then it fizzles out again. The office kelpie rides the robot vacuum round the rug the whole time.

How a job runs

  1. Have a chat

    Tell us what you need, even if it's only a few lines. We'll ask some questions and tell you straight if we're the right fit.

  2. See it first

    You get a drawing or a plan to comment on, then a fixed price and a finish date in writing.

  3. We build it

    We keep you posted along the way, and you can check it as it comes together.

  4. Handover

    We show you how it all works and hand over every file and login, in your name.

Questions

What does it cost?

It depends on the job. After a quick chat you'll get a fixed price in writing, before any work starts. Nothing extra goes on the bill without your OK.

How long does it take?

Most first versions take one to six weeks, depending on the job. You'll have a finish date in writing before we start.

Do you only work with businesses?

No. Plenty of what we do works just as well for you as for a business: a personal website or portfolio, invitations, floor plans turned into 3D, or sorting out your paperwork. It runs like any other job: a chat first, then a fixed price in writing before we start.

Do you work outside Perth?

Yes. We meet in person around Perth, and online anywhere else.

Do you use AI?

Yes, for the parts it does well, like reading messy notes or writing a first draft. Anything it drafts that goes out in your name waits for a person's OK, and we'll always tell you which tools are used and where your data is kept. We can also set up ChatGPT, Gemini or Claude for you or your team, and show you how to get good use out of them.

Who owns the finished work?

You do. Once it's paid for, every file, account and login is handed over in your name.

Are the places on your street real?

No, we made them all up. The bakery, the pub, the house and the rest don't exist. We'll add work for our clients as it's finished and they're happy for us to show it.

About me

A cartoon of me in a black Code, Shape, Automate, Repeat T-shirt, waving hello with a laptop under my arm

I'm Andrew Barltrop. CSA grew out of my love of technology and a drive to make everyday jobs easier and quicker to get done.

I've spent the past 18 years working as an electrician, telecommunications technician and gas fitter, but computing and digital media have always been my real passion.

I also run an appliance repair business, Authorised Service Agents Pty Ltd. I was already building automations and digital tools for it, so starting CSA just felt natural.

Working across commercial, industrial, mining, and oil and gas sites has given me a real understanding of what people need to make their business run smoother and faster, and get time back for themselves and their family.

The last lot's yours

Tell us what you need in a few lines. We'll reply within two working days.
