Fixed-price review
Backend/API Audit
A focused review of an existing C#/.NET backend or API — architecture, reliability risks, and maintainability, with written findings and prioritised recommendations.
The first step is a free 20-minute call, then a fixed-price quote: book the call or describe the problem.
Unlike an open-ended engagement, this is scoped as a fixed piece of work with a defined deliverable: useful as a starting point before committing to something larger, or as a standalone second opinion on a system you already know needs attention but haven't had time to properly assess.
What gets reviewed
- Architecture and design patterns — how the backend or API is structured, and where that structure is working against you
- Reliability risk — error handling, resilience under failure, dependency health, and single points of failure
- Maintainability — test coverage, code organisation, documentation, and how easy the system is to change safely
- Anything specific you flag up front — a slow endpoint, a recurring incident, a part of the codebase nobody wants to touch
What you get
A written findings report with prioritised recommendations — what needs attention first, what can wait, and why. A short walkthrough call to talk through the findings is included; implementing the recommendations is a separate, further-scoped piece of work if you want it actioned. You have seven days after the walkthrough to come back with questions by email, and I'll answer them. If something bigger comes out of it, we can talk about that as its own piece of work.
What I need from you
To do this properly I need read-only access to the code, whatever documentation exists, and someone who can answer questions for about an hour in total. You'll have the findings within ten working days of me getting access.
Where I draw the line
This is a review and a set of recommendations, not a rebuild. I won't push a rewrite where a smaller fix will do, and I'll say plainly where a finding needs deeper investigation than a fixed-scope audit can cover. If the audit surfaces work you want delivered, that's scoped and quoted separately once you've seen the findings.
This review covers one application: a single repository that builds and deploys as one service. If you have several services or more than one codebase, tell me on the call. I'll either suggest which one to review first or quote for the wider piece before anything starts.

Frequently asked questions
What does a backend/API audit actually cover?
The audit reviews an existing C#/.NET backend or API across three areas: architecture and design patterns, reliability risk (error handling, resilience under failure, dependency health and single points of failure), and maintainability (test coverage, code organisation, documentation and how safely the system can be changed). You can also flag specific concerns up front, such as a slow endpoint, a recurring incident or a part of the codebase nobody wants to touch.
What do I get at the end of a backend/API audit?
You receive a written findings report with prioritised recommendations, setting out what needs attention first, what can wait, and why. A short walkthrough call to talk through the findings is included. Implementing the recommendations is not part of the audit; if you want the findings actioned, that is scoped and quoted separately once you have seen the report.
How much does a backend/API audit cost?
The audit is a fixed piece of work with a defined deliverable, so it is quoted as a fixed price agreed in writing after a free 20-minute call to understand roughly what you want reviewed. See how pricing works.
Will the audit recommend a full rewrite of my system?
Not by default. The audit is a review and a set of recommendations, not a rebuild, and Jamie will not push a rewrite where a smaller fix will do. Where a finding needs deeper investigation than a fixed-scope audit can cover, the report says so plainly. Any follow-on work you choose to pursue is scoped and quoted separately. Delivery is 100% remote.
