From Prototype to Production
AI tools made building an MVP astonishingly easy. The hard part is everything that comes next - the work that doesn’t show up in a demo but absolutely matters the moment a real customer signs up.
We take your AI-built prototype and harden every layer it needs to survive contact with real users, real money, and real attackers.

About
Hi, I’m Mark.
I’ve been building production software for more than 2 decades. SaaS, payments, integrations, and the unglamorous infrastructure that turns a working demo into a business people can actually run on.
Brainbook is the consultancy I built around that experience. Senior engineering, done properly. When you work with us, you’re working directly with me.
How we work
Flexible engagement, real results
One-off audits
Fixed-scope reviews with a detailed report and actionable recommendations. No ongoing commitment required.
Project-based
Defined scope, clear milestones. We build features, fix problems, or modernise legacy systems end-to-end.
Retainers
Ongoing development support. We embed with your team as a trusted extension of your engineering capacity.
