Yep, I'm one of the few that can lead your software as your Fractional CTO, or my engineering team and I can build it for you. I've led technology for 253 Australian companies over 16 years.

A letter from one business leader to another

Does any of this sound familiar?

Dear business owner,

Most people I speak to are in one of three places:

  1. They have quotes that are tens of thousands of dollars apart,

  2. They have a project that's been "nearly done" for months, or

  3. They built a first version in a tool like Lovable, and now it needs to work for real customers.

They all have the same problem. They're making decisions about software, and nobody on their side can check them.

A developer explains a decision. It sounds reasonable. But is it the right call, or just the easy one? Most owners can't tell. Many tell me they lost track of their project the moment it got technical.

You're probably thinking about these things

  • 01

    Why are these quotes so far apart?

  • 02

    Is our project actually on track?

  • 03

    What happens if our developer walks?

  • 04

    Where would AI actually save us time?

None of this is your fault. You run a business. You're not a software engineer, and you shouldn't have to be.

But it does make problems hard to spot.

I recently looked at two quotes for the same project. They were $60,000 apart. Both looked reasonable. The gap came from guesses about scope that neither developer wrote down.

Projects that stay "nearly done" are similar. The last stretch holds the work nobody planned, like testing, security and connecting to your other software. Without someone checking, you find out when the deadline passes.

AI prototypes have a related problem. They can look finished. But they're often not ready for real customers, real data or proper security.

In almost every case, one thing was missing. Someone on the owner's side who understood the technical decisions.

Someone to check the quotes. Someone to say no to features that aren't worth building. Someone to hold the developers to their promises.

That's the role I take on. As a fractional CTO, I'm your technical leader for part of the month. You only pay for the time you use. If you need software built or fixed, my team of 26 engineers can do it. I lead the work.

The first step is a free audit. We talk for 30 minutes. Then I send you a written plan: what to build first, what to leave out, roughly what it should cost, and what to check in your quotes.

The fixed-price trap

Agencies are paid to build, not to get you a result.

A fixed price and fixed scope can feel safe. But it is the most expensive way to build software. From the very first meeting, requirements expand, and from the very first release, iteration begins. A fixed-scope contract has room for neither, so changes get billed as extras.

What the fixed-price agency does

Quote a fixed scope before they understand what you need

Add extra to the quote to cover unknowns

Build what was agreed in month one, even if it's no longer right

Charge for every change request

Treat improvements after launch as out of scope

Move the risk to the person least able to see it coming — you

What I do instead

Work out what you actually need before giving you a quote

Plan for the scope to change

Budget for improvements after the first release

Charge for the work that's actually done

Show you progress and decisions every week

After 16 years and around 250 engagements, I've seen what fixed price does to a project, so as your CTO I make the calls before anything is built

“Sam took the time to understand our business and knew all the tech we needed. It was a pleasure to work with him and his team as they acted as an extension of our team.”

Luke Schwigtenberg
Head of R&D, Banktech

“In a short period of time, Sam demonstrated an exceptional ability to align the right technical expertise with our specific needs.”

Tim Buric
CTO, Agilyx

What I do

What having a technical leader on your side looks like

Technical strategy and roadmap

What to build first, what to leave out, and what it should cost - all written before anyone quotes you.

Quote and vendor evaluation

I read the proposals and contracts and tell you which to trust.

Decisions before code is written

Custom or off the shelf, what goes into version one and how it connects to what you already use. I'll help you make the decision early, with your interests in mind.

Running the build

Weekly check-ins, releases in stages and your staff using it early. You see progress every week.

Code, security and cost reviews

Whether what's been built is any good, whether it's secure and what it will cost to run, with a clear list of what to fix first.

Hiring and structuring your tech team

Who you need, how to vet them, and how to set up the team so it works without you chasing it.

What you get

1

Software that works after launch
Software that works after launch

And keeps working without needing a rebuild a year later.

2

Progress you can see

Weekly updates you can follow.

A bigger secret

We're a small but powerful team. I work with no more than a dozen clients at any time.

After the audit, what you do next is up to you. If you'd like to work together, I'll lead the project as your CTO and my engineering team will do the work. Here's what that looks like.

Before we build

We agree on what the software needs to achieve

More downloads, more repeat orders, fewer support calls, hours saved for your team. We set the goal first and measure the build against it.

Leadership

I make the technical decisions for you

Custom or off the shelf, which cloud provider, how it connects to your other software, whether AI belongs in it. I decide these before any code is written and explain why, so you're never confused.

During the build

You always know where it's up to
You always know where it’s up to

You deal directly with me and the developers working on your software. Daily check-ins mean there are no surprises. Ever.

how we build in 2026

Software is built differently now

It's 2026. Good engineering teams now use AI agents to write, test and check code. This is called agentic engineering, and it's how we build every project.

It means faster delivery and a lower bill for you.

Agents do the routine work

AI agents write and test code through a plan I set, one ticket at a time. You see every ticket.

Engineers check every change

A senior engineer reviews every change before it's released. Nothing goes live without a person signing off.

You pay for less time

Months of work lands in days. The difference goes into your budget, not my margin.

Launch

We roll it out in stages

My team builds in stages and gets your staff or customers using it early, so it fits the way they actually work.

After launch

We keep it working

My team keeps your software running, fixes issues as they come up and adds features as your business grows.

Security

The right level of security for your business

Not every product needs bank-level security. Some do. I'll work out what yours needs, and keep it in proportion to your risks and your budget.

You get the risks explained without jargon, so you can decide. If you want the technical detail, I'm happy to go as deep as you like.

Sensible basics, always

Encrypted data, two-factor sign-in and tested releases are standard on every project.

Risks you can understand

A short list of risks, what each could cost you, and what it takes to fix. You decide what to act on.

As technical as you want

If you or your team want the detail, I'll walk you through it. If you don't, I'll stick to the non-technical overview.
