I’m Christian. I’ll review your app myself.

I build and maintain production software. I use AI tools to explore the code, then personally check every finding and recommendation.

Experience with live apps: I work on production healthtech apps and integrations that handle sensitive data.
Advice you can act on: I investigate problems in existing code and improve reliability and performance. Your report will give you clear priorities and practical next steps.

You don’t need to have it all figured out.

It works for you. Will it work for your first customer?
Could one customer see another customer’s private data?
What will you say if it breaks during your first demo?

A focused review. A clear written report.

App screen showing one agreed project-save journey, with the Save button marked.

One concern or key journey.

We’ll agree one focus by email. I’ll look at that part of your running app and the relevant code.

Report finding that payment was taken but no order was created, with the recommended fix to create orders from confirmed payment events. — Illustrative example.

Your findings, with evidence.

See what I checked, what I found, and what to tackle next. Includes evidence and screenshots where useful.

Example finding, a user’s question, and an annotated email reply explaining what the reviewer means. — Illustrative example.

One round of email clarification.

Send your follow-up questions in one email within seven days of receiving the report.

Get the written report.

I’ll send it within three working days of our agreed start date, once payment and required access are ready. You can request one clarification round by email within seven days.

Before we start.

Is this right for my app?

It’s for solo founders preparing a running web app for first users or a customer pilot. We’ll focus on one agreed concern or key user journey and the relevant code.

How do the dates and access work?

We agree the scope, required access, and start and delivery dates by email before payment. I’ll send a private upfront payment link once we agree. The three-working-day turnaround starts on the agreed start date once payment and required access are ready. If required access is late, we’ll reschedule by email.

What does the report include?

The report covers what I checked and any limits, findings with evidence, why they matter, and prioritised practical next steps. It isn’t a full codebase review or security certification. Fixes, new investigations and review of fixes are separate. One round of email clarification is available if requested within seven days of delivery.

Can I ask questions about the report?

Yes. One round of email clarification is available if requested within seven days of delivery.

How do you use AI and my app data?

I use AI tools to help explore the code. I personally check every finding and recommendation before it reaches you. Before I start, we’ll agree which AI tools may be used with your code and data.
