Plenty of companies can write good code. Software projects usually go wrong in the planning and in the decisions made along the way, so that's where we've focused how we work.

Direct access to me and my developers
You'll deal directly with me and with the developers working on your project. There's no account manager passing messages back and forth.

We agree on the goal before we start
Before my developers begin, we agree on what the software needs to improve for your business. We measure the project against that goal, and we don't consider the job done until it's improved.

A CTO's judgement on every project
I've spent 16 years making tech calls. I'll tell you which risks are worth worrying about and if there's a simpler way to get what you need. Every suggestion I make comes back to what your business is trying to achieve.

Technology chosen to suit your business
I recommend the approach that makes sense for your goals and budget. Sometimes that's a simpler build than you expected, or an existing product with a few changes. If it is, I'll tell you.
