The Entrepreneurial Engineer

After 25+ years in engineering, on site, in boardrooms, and across continents, it’s time to give back.

I’ve made the mistakes, worn the pressure, led the teams, and built the projects. 

And now?

I’m on a mission to help engineers become more than just technically competent.

I’m here to help them think like entrepreneurs.

The Entrepreneurial Engineer is about packaging up everything we learn across a career, the wins, the lessons, the pivots, the pressure, and turning it into something that actually moves the needle for others.

It’s not a course. 

It’s a mindset.

I mentor, coach, and support the next generation of engineers to:

Build confidence

Win work (not just do it)

Accelerate their growth

Communicate with clarity

Navigate careers with courage

Because the age of the technical-only engineer is over.

Today’s engineers need to think, influence, and lead.

That’s why The Entrepreneurial Engineer is built on one philosophy:

THINK — differently about your value, your path, your edge.

CREATE — with purpose, clarity, and bold thinking 

SHAPE — the future of the industry by becoming the kind of engineer others want to follow. 

This is the advice I wish I had earlier.

Now I this is my mission.

Let’s shape what’s next.

Hope in a Suitcase Australia

Hope in a Suitcase is a non-profit organisation run entirely by passionate and dedicated volunteers and through donations of new items from the community, and the generosity of groups and corporations. Since its beginning in 2018, the charity has grown to be able to provide suitcases for children going into foster care or out-of-home care, throughout NSW, Queensland, Victoria and Tasmania.

Children with a strong sense of self-worth feel competent to cope with the basic challenges of life and feel worthy of success and happiness. It gives them a solid foundation for their learning and development. It is empowering and makes room for positive change in a way nothing else can.

Design, Construction and Commissioning Manager

On a mission to help engineers to be more entrepreneurial | Project Director @ Legacy Property Chartered Civil and Structural Engineer passionate about design thinking, innovation and challenging the status quo.

The best engineers don’t just design. 


They think. 


They create. 


They lead. 


They shape the future. 


That’s been the theme of my 25+ year career, starting on site in trenches, with pipes, pumps and concrete, and evolving into a Chartered civil and structural engineer, Director, Advisor, Mentor, Coach, and community builder.


My career has spanned over $5B of infrastructure and development projects across Australia and Vietnam. 


But the turning point came when I realised engineering wasn't just about drawings and approvals, it was about value, clarity, and execution. 


I once saved a client $1M in 1 hour of drawing review. 


That shift changed everything.


Today, I lead Vinculum Advisory—an engineering consultancy focused on specialist engineering and delivery management for development and infrastructure projects across NSW. We help our clients navigate the most complex components of design, risk and delivery, bringing technical clarity and strategic thinking to every phase.


I also serve as Technical Director at Legacy Property, where I drive value engineering and strategic outcomes across their portfolio. My role spans due diligence, planning, approvals, masterplanning and delivery, ensuring smarter outcomes, faster execution, and best-for-project results.


My technical strengths are matched by a deep commercial lens, blending engineering logic with development and delivery strategy.


And that mindset now powers everything I do:


THINK — Strategic vision, technical excellence, and future-focused frameworks. 


CREATE — Platforms like 3 Degrees of Separation and The Entrepreneurial Engineer to connect and elevate engineers and entrepreneurs.


SHAPE — Real outcomes, team building, smarter delivery, and future-ready professionals.


I speak to rooms, mentor individuals, and advise businesses, not just to talk about engineering, but to talk about where our future is going.

I also have a podcast that dives into real people, their stories and highlights what makes them more entrepreneurial.

https://youtube.com/@theeepod?si=tlDxFeznvs4UdPxt

Because the future of this industry doesn’t belong to the most technical. It belongs to the most adaptable. 

The most curious. 

The most willing to lead.

If you’re an engineer, entrepreneur or young professional ready to think bigger, create and shape your future, and make more impact, let’s connect.

Urban Design Fail...

Humans will always find the path of least resistance.

You can design all the fences, bollards, and barriers you want 

But if it doesn’t align with how people actually move, they’ll carve their own route every time.

That little dirt track?

It’s called a desire path, and it’s one of the most honest forms of feedback in urban design.

If you’re designing for people, start by watching where they walk.

On a mission to help engineers be more entrepreneurial. Passionate about design thinking, innovation, tech, future, AI and challenging the status quo.

This is innovation...

The kind I dreamed up back at Uni…

And then did absolutely nothing with.

Israel, one of the sharpest water-tech nations on earth, went and built smart pipes that generate clean electricity.

As water flows through the network, it spins tiny internal turbines.

No dams.

No land take. 

No mega-infrastructure.

Just using pressure that already exists.

Streetlights. 

Sensors. 

Data Centres.

Even small communities…

Powered by water doing what water already does.

It’s a reminder that the biggest breakthroughs are usually hiding in plain sight.

If you’ve got an idea, act on it.

Because if you don’t, someone else will.

Engineers want the title, but not the work in the trenches...

Everyone wants to be called:

Senior Engineer, Design Manager, Project Lead, or Director.

But few want the 5 a.m. problem-solving sessions, the rework, the client calls that go sideways, or the pressure of delivering when the data doesn’t add up.

The pain is the process.

The bruises are the proof.

The pressure is what turns you from engineer to leader.

Stop chasing the trophy, start earning the scars.

Design Fail...

This footpath isn’t a design feature.

It’s a design fail someone had to work around.

If you’ve spent more than 5 minutes in this industry, you already know this truth:

Half of engineering is solving problems.

The other half is fixing problems someone else created.

You don’t always get a clean slate.

You don’t always get perfect drawings.

You don’t always get ideal levels, alignments, clearances or services.

But drainage needs to drain.

Sometimes you inherit:

• poor planning

• missing coordination

• a clash no one bothered resolving

• a structure that magically “appeared” during construction

• a decision made 10 years ago by someone who’s now retired

And you still have to deliver.

This footpath is exactly that:

A contractor trying to turn a bad situation into a finished product, even if the geometry says otherwise.

Is it pretty?

No.

Is it ideal?

Definitely not.

But is it reality?

Every. Single. Week.

Because great engineers aren’t the ones who get perfect conditions.

Great engineers are the ones who can look at a mess and still produce something functional, safe, and that works.

Phi. 

In the architecture of this 8th century Japanese Pagoda there are several relationships of the Golden Ratio (Phi). 

This temple was designed and built carefully so that every detail corresponds to the Golden Ratio of Nature, thus displaying a design aligned with the fractal harmony of the Universe. 

It is no accident that her beauty is often called "frozen music."
ㅤ
"The good, of course, is always beautiful, and the beautiful never lacks proportion." – Plato

Today's thought:

No matter your age, you'll always wish you started younger. 

But today is the youngest you'll ever be...

Read that again.

Tesla’s Optimus humanoid robot has reached a major milestone.

It can now run with true airborne strides. 

wow...

New footage shows Optimus lifting completely off the ground for fractions of a second with each step.

Something only a handful of advanced robots have ever achieved. 

This type of bipedal running demands precise balance, shock absorption, smooth motion control, and enough speed to sustain brief “mini-jumps.” 

The progress signals a huge leap in Tesla’s robotics program.

Optimus is rapidly moving closer to real-world agility and human-like mobility.

Find your age on this chart.

There’s still hope....

Too many people tell themselves they’re “too old”

Too old to switch careers.

Too old to start a business

Too old to chase an idea.

But here’s the truth:

Colonel Sanders started KFC at 65.

Ray Kroc scaled McDonald’s at 52.

Vera Wang designed her first dress at 40.

Your age isn’t the finish line.

 It’s just the chapter you’re in.

If you’re 23 and lost, you’ve still got decades to figure it out.

If you’re 46 and frustrated, you’ve still got decades to reinvent yourself.

If you’re 60 and restless, you’ve still got time to leave your mark.

It’s never too late to start.

The only thing that makes it too late is if you don’t.

Engineers who show up.

At Vinculum Advisory, we don’t believe in “desktop engineering.

We believe in delivery.

That means being on site.

In the dirt.

Mark Cremona and his team, getting it done...

With boots on the ground, not just opinions in a PDF.

The new utes aren't a flex, it’s a statement.

We’re investing in the tools that get our people where they need to be. 

On the ground, on site, with the Client, with the Contractor, solving the real problems.

Projects don’t move because of emails.

They move because someone actually showed up and made a call.

That’s who we are.

That’s how we deliver.

When some things shouldn’t be automated...

Not every tool needs a battery.

Not every process needs AI.

Not every problem needs a system.

Sometimes… 

You just need a hammer.

Most engineers think the game is won by the smartest person in the room.

It’s not...

It’s won by the engineer who raises their hand and says,

“I’ll figure it out.”

Your degree won’t save you.

Your HDs won’t save you.

Your “IQ” won’t save you.

But your willingness to try…

to question…

to build…

to iterate…

to take responsibility when everyone else steps back.

That’s the difference between an engineer who stays stuck…

and an engineer who becomes unstoppable.

In this industry, the people who win are the ones who take action before they feel ready.

Your ‘I can’ will take you further than your IQ ever will.

Why do engineers make the best project managers??

Because engineers are already trained for the hardest part of project management:

Making decisions when the information is incomplete.

Most projects fall apart not because of design,

But because no one wants to call the shot when the variables aren’t perfect.

Engineers are built for that environment.

Engineering teaches you how to:

Break complexity into simple parts

Spot risk early, before it becomes a disaster

Ask sharper questions

Challenge bad assumptions

Read between the lines (and drawings)

Understand how everything fits together, not just the task in front of you. 

That’s why engineers step into PM roles and instantly change the temperature in the room:

Meetings become decisive.

Programs tighten.

Consultants sharpen up.

Contractors stop hiding problems.

Scope creep dies fast because someone can challenge it before it turns into a variation. 

If you're an engineer thinking about jumping into PM work, here’s the truth:

You already have the core skills.

You already think in systems.

You already anticipate failure before others see it.

You already understand design, delivery, risk, sequencing and constraints better than most PMs ever will.

The only gap?

 Communication

 Influence.

Getting people to do what they said they’d do.

Systems. 

And those are learnable.

So don’t wait for someone to “tap you on the shoulder.”

Engineers make exceptional project managers, and you’re probably closer than you think.

Engineers don’t need motivation.

We just need a deadline that’s close enough to hurt.

Nothing transforms productivity like the last minute.

Suddenly the fog clears.

Scope becomes obvious.

Decisions get made.

And that drawing you’ve been “thinking about” for 3 weeks…
gets finished in 45 minutes.

But here’s the truth no one tells young engineers:

The last minute isn’t a strategy.

It’s a symptom.

A symptom of unclear priorities.

A symptom of fear of starting.

A symptom of perfectionism disguised as “planning”.

The real pros?

They create artificial last minutes.

They chunk the work.

Set micro-deadlines.

And turn panic into process.

So yeah, nothing makes an engineer more productive than the last minute…

But the ones who lead?

They don’t wait for it.

They build it into their system...

Know when it’s time to escalate to an engineer...

If this feels like your workload heading into Christmas…

then maybe it’s time to find a new circuit breaker.

Because you can’t keep plugging more and more into a system that’s already overheating.

Whether that system is your job, your team, or you.

So before Christmas hits, do the one thing most engineers, managers, and founders refuse to do:

Pull the plugs that don’t matter.

Trim the tasks.

Park the noise.

Set expectations. Especially with clients. 

Clear the load so you can actually finish the year with your sanity intact.

Then before the shutdown and celebrations kick in.

Spend one hour, a day, a minute, mapping out what Q1 2026 needs to look like before it looks like this picture again.

Reset.

Rewire.

Sort it out now.

And to all the clients and contractors out there.

There will be a 2026.

Iran is currently producing some stunning brick architecture...

Sydney’s Lower North Shore has a problem no one wants to talk about…

…and it’s not over development.

It’s schools.

Right now the NSW Government is pushing Transport-Oriented Development (TOD), density around Metro stations, and huge rezonings that massively increase yield across the Lower North Shore.

Developers get uplift.

The Government gets revenue.

Communities get… stuck.

Because while we’re adding thousands of new residents, we haven’t added the schools to match.

Not even close.

Let’s look at what’s actually happening in the Lower North Shore:

Greenwich Primary is bursting at the seams, but there’s no Greenwich High School for those kids to move into.

Naremburn School? Needs expansion. 

North Sydney Dem, no high school. 

Cammeraygal High? Completely full. Waiting lists. Overflow. Portable classrooms.

Mosman High is one of the only remaining realistic public options… for a region with some of the fastest-growing density in the state.

Private schools are laughing. 

Rezoned areas around Crows Nest, St Leonards, North Sydney, Artarmon, Chatswood, thousands more apartments approved or under assessment.

The Government is benefiting from the uplift… while the infrastructure that actually matters for families is falling behind at light speed.

We keep hearing about “liveable density.”

Well, liveability starts with education, not just train stations. 

We talk about affordable housing. 

We talk about TOD precincts and 30-minute cities.

But nobody asked the most obvious question:

Where are all these new kids supposed to go to school?

This is not a NIMBY issue.

This is not an anti-development rant.

I’m pro-density when it’s done right.

But density without essential services is not planning, it’s chaos.

Sydney has world-class engineers, planners, architects, and designers.

We can build expansions above existing campuses, or adjacent to our open spaces.

We can design vertical schools above rail corridors, above plazas, above community hubs, it’s not hard, the solutions are there.

But right now?

The Government is approving density faster than it can educate the people living in it.

That’s the real crisis.

As a parent, as an engineer, and as someone who works deeply in development and infrastructure, I’m worried.

Because this isn’t just a planning oversight…

It’s a generational failure in the making.

It’s time to:

Unlock our existing schools and expand them with smart engineering. 

Deliver vertical schools in TOD precincts as part of uplift incentives.

Ringfence uplift revenue or contributions for local education infrastructure.

Treat schools as essential infrastructure, because they are.

If we can build skyscrapers above Metro stations, we can build classrooms.

And if the we can’t get this right, what hope do other communities have?

This is about more than planning.

It’s about our kids, and their kids.

I’m about to release a set of online courses for engineers.

If each course was $150, which one would you actually pay for?

Pick one:

🔥 Australian Standards for Migrant Engineers

(Understand AS codes, design expectations & local practice)
