About
Senior engineering, done properly.
Brainbook is a Melbourne-based software consultancy. We help founders and growing businesses ship software that works in production - the payments, the performance, the security, and now the AI. Two decades of doing the hard parts right.
The person behind it
Hi, I’m Mark.
I’ve been building production software for more than two decades. SaaS platforms, payment systems, ERP and e-commerce integrations, dealer portals, and the unglamorous infrastructure that turns a working demo into a business people can actually run on.
Over the years I kept seeing the same thing: the gap between software that looks like it works and software that holds up under real customers, real money, and real load. Closing that gap is what I’m good at, and it’s what Brainbook exists to do.
Brainbook is the consultancy I built around that experience. When you work with us, you work directly with me - no offshoring, no junior dev being “managed” over your project, no account manager between you and the person writing the code.
What we do
We specialise in the things that are easy to get wrong.
Brainbook isn’t a generalist agency. We go deep on the areas where mistakes are expensive and experience really matters - payments, performance, compliance, integrations, and shipping AI that holds up in the real world.
We work as fixed-scope audits, project-based builds, or ongoing retainers - whatever fits where you are. Many clients start with a one-off engagement and stay on as we become their trusted engineering partner.
