- Business intelligence
- Decision layer
How we work
Our engagement process
Four stages, from the first conversation through handover.
01
Discover
A short look at the systems, constraints, and the problem behind the request — before we propose a build.
02
Plan
Architecture, sequence, responsibilities, and what done looks like, written down and agreed before production work starts.
03
Build
Short cycles with demos you can attend. You review working software, not a status report.
04
Hand over
Planned releases, tests, and documentation your team can operate without us.
Optional ongoing support
Handover is part of every engagement. If you want us to keep maintaining or extending the system afterwards, we agree that as a separate, scoped retainer.
Why work with CodexSmith
Clear commercial terms
For a clearly defined scope, we can agree on a fixed fee. When requirements need further exploration, we begin with a short discovery. We agree on the pricing approach before work begins.
Same team throughout
You work with engineers who stay involved throughout the engagement, supported by a technical lead accountable for quality.
Security in scoping
We can sign an NDA before you share confidential information. During scoping, we agree on how your security and data-handling requirements will be addressed.
You see the work
You communicate directly with the engineers delivering the work and review working software as it progresses.
Reflections of our work
Candidates no longer bounce between mock tests in one place and practice banks in another. They see which question types are holding the score down, practise those specifically, and come back to a mock with a clearer plan.
Agree on the work before it begins
Your proposal should make scope, deliverables, responsibilities and commercial terms clear.
