Building a prototype?
You have something that seems to work on the surface, but want to know whether the underlying technology makes sense before investing more time or money.
Gain confidence in your prototypeCode Confidence by Mark Jackson
Gain confidence in your AI-generated code.
Independent technical reviews for founders and small teams.
Understand what’s working, what needs attention, and what to improve before your next milestone.
Reviews starting from £300. No technical background required.
Sound familiar?
AI makes it easier to build something. Knowing whether it’s ready for your next milestone is a different question.
Getting ready to launch?
You’re ready to put your software in front of customers, but want to understand what could go wrong — and what needs attention before real people rely on it.
Gain confidence before launchBuilt a tool for your team?
You’ve created something useful, but want to know whether it handles your business data appropriately and will be reliable enough for everyday use.
Gain confidence in your internal toolPreparing to approach investors?
You want a clearer picture of your technology, its risks and its limitations — so you can answer investors’ technical questions and explain what needs improving.
Gain confidence before investment discussionsWhat you take away
A clear picture of your software, with recommendations you can act on.
Preparing for investment? We can also look at your architecture, dependencies and documentation.

Reviews from £300
Based on the complexity and size of your project. Fee agreed before any work starts.
Ask about a review for your projectWhat I look at
The review is shaped around your next milestone. A small prototype and a customer-facing application don’t need the same level of scrutiny.
Functionality & reliability
Does it do what you expect — including when inputs are unexpected or something goes wrong?
Security & privacy
Are accounts, permissions, secrets and sensitive information handled appropriately?
Structure & maintainability
Can someone understand, change and support it without breaking something else?
Performance & costs
Are there avoidable bottlenecks, inefficient queries or unexpectedly expensive services?
Deployment & operations
Can you release updates, spot problems, back up important data and recover when needed?
AI & data integrations
Where relevant: are data flows, model outputs and third-party integrations handled sensibly?
A scoped technical assessment, not a security certification or a guarantee that software is risk-free. Specialist testing may be recommended where needed.
How it works
Tell me what you’re building
We discuss what it does, who will use it, your concerns and the milestone you’re working towards.
Agree the scope upfront
We agree access, deliverables, timing and a fee before the review starts. No open-ended engagement.
Review, then explain
I examine the relevant code and setup, prepare the findings, and walk you through the recommendations.
Choose your next step
Use your prioritised recommendations to decide what needs attention before your next milestone and what can wait.
Your reviewer
I’m a software and data engineer with more than a decade of experience building production systems. My specialism is data, but my work spans applications, backend systems, cloud infrastructure and practical AI.
I bring a generalist’s view of how the pieces fit together — and a pragmatic approach to deciding what matters now, what can wait, and when specialist expertise is needed.
Production experience, not just prototypes.
Explore my experience I’ve built a financial data platform supporting over 100,000 clients, delivered customer-facing analytics, and redesigned a processing platform to reduce AWS costs by 90%.
Your next step
Email me a brief description of your project, your next milestone and your main concern.
I’ll reply to clarify what you need and whether I’m a good fit. We’ll then agree the scope, fee and timing before you decide to go ahead.
A few useful answers
What technologies can you review?
I work across application development, data, backend systems, frontend integrations and AI. We’ll discuss your stack first. If your project needs expertise outside my remit, I’ll say so before we agree the work.
If there are any issues, can you help fix them?
Yes. After completing the review, I’ll have a good understanding of your project. If you need help resolving issues before your next milestone, I’d be happy to provide an additional quote for suitable work.
How much does it cost, and how long does it take?
Reviews start from £300, based on the complexity and size of your project. We’ll agree the fee and delivery timing before any work starts.
How will you handle code access and confidentiality?
We’ll agree confidentiality requirements, minimum necessary access and how materials will be handled before sharing the code. Any proposed use of external AI tools must be agreed in advance.
What are the limits of a review?
A review supports informed decisions; it can’t eliminate every risk. It isn’t a security certification, compliance sign-off or substitute for specialist testing. Investment preparation isn’t a formal due-diligence opinion or an assurance that investors will approve.
