Most software projects go wrong in the planning, not the coding. As the CTO on your project, I make the key technical decisions before any code is written, so you don't pay to fix them later.

Before anything is built, we agree what your software has to do for your business. That's how I measure success; it's not about how many features were shipped.

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