PERMISSIONS
Can a user access someone else’s data?
We check API and database permissions using accounts with different roles and ownership.

You built it with AI.Now let’s get it ready
for real users.
Engineering reviews and hands-on fixes for products built with Lovable, Cursor, Claude Code and other AI tools. We review bugs, security, performance, architecture, databases, reliability and scalability, and make the changes your code needs.
No repository access or credentials needed to get in touch.

BEFORE YOU LAUNCH
The demo works. There’s more to check.
Some problems are easy to miss when you’re the only person using the product. Try it with two accounts, a larger dataset or a payment that fails.
PERFORMANCE
Does the page slow down with more data?
We inspect queries and external API calls to find where requests are spending time.
ERROR HANDLING
Can a failed operation be retried?
We check what was saved before the error and whether a retry could duplicate payments, invitations or other records.
These are some of the cases we check during a review.
WHAT WE CHECK
From how your product works to how it ships.
The checks depend on your product and the problems you want to solve.
01
FIX
Bugs & edge casesFailed logins, incomplete saves and operations that produce unexpected results.
02
SECURE
SecurityWho can read and change data, where credentials are used and how payments are handled.
03
SCALE
Performance & growthSlow queries, repeated requests and jobs that stall as usage increases.
04
HARDEN
ReliabilityWhat happens after an error, how you find out and how you recover data and operations.
05
CLEAN
Architecture & codeDuplicated rules, code that is hard to change and missing tests for important behaviour.
06
SHIP
Release preparationConfiguration, tests of the release build and a way to roll back if needed.
FOR PRODUCTS ABOUT TO LAUNCH
Production Readiness Review.
We check the parts of your product your first customers will use. You get an explanation of what needs fixing before launch, what can wait and what we couldn’t verify.
- Review of code, database, APIs and configuration
- Problems explained with examples and priorities
- Suggested fixes
- A call to discuss the findings
HOW TO READ THE REPORT
READY TO SHIP
No significant blockers in the reviewed scope.
FIX BEFORE LAUNCH
Important issues to address before release.
NOT PRODUCTION READY
Critical issues or blockers need attention before launch.
THIS ASSESSMENT REQUIRES A PROJECT REVIEW.
WHEN YOU NEED FIXES
Finding problems
is useful.
Fixing them is better.
If you already know what’s broken, we can start there. During a Fix Sprint we reproduce the issue, make the change and test the result. We agree on the work before we begin.

FOR PRODUCTS ALREADY IN USE
Is your product slowing down or getting expensive to run?
We examine queries, caching, background jobs and cloud services to find the cause. You get suggested changes and measurements to compare performance before and after.

HOW WE WORK TOGETHER
From the first conversation to delivery.
01
DiscussTell us about the project
We discuss what you’ve built and where you need help. We propose the work, timeline and price.
02
ReviewWe examine the product
We read the code and test the agreed workflows, including data access and deployment where needed.
03
PrioritiesWe discuss the findings
We show you the problems and explain which changes we recommend making first.
04
FixesWe make the changes
If the work includes fixes, we implement them and check that they solve the issue without breaking other flows.
CODE AND TECHNOLOGY
We start with the code you already have.
You may have built in Lovable, worked in Cursor or used several tools. The review covers your code, database and connected services.
Technology references only. No partnership or certification is implied.

01LOVABLE02CURSOR03CLAUDE CODE04ALREADY LIVE05PRE-LAUNCH
“My SaaS started in Lovable.”
We check the product’s features, backend and permissions.
“Cursor helped build most of it.”
We review code that is hard to change and tests of the main features.
“Claude Code wrote a lot of the product.”
We check APIs, data changes and error handling.
“We’re live. Things are starting to break.”
We start with the errors and slowdowns you’re seeing.
“Our first paying customers are coming.”
We check sign-up, payments and access before launch.

+ CODE AND PERMISSIONS NEED A REVIEW
01What does a Production Readiness Review include?
We agree on the areas to check, such as code, databases, permissions, performance and deployment. You get the findings, examples and suggested fixes in priority order. We also list anything we couldn’t verify.
02How do I know whether AI-generated code is ready?
Test the workflows your product needs, including failure cases. A working demo isn’t enough: you also need to check permissions between accounts and what happens when an operation such as a payment is repeated.
03Can you review a Lovable, Cursor or Claude Code project?
Yes. We start with the code and services you already have. You don’t need to switch tools to get a review.
04Do you check Supabase and RLS policies?
Yes. We check what users can read or change with different accounts and roles, including grants, functions and backend access. A publishable key in the frontend is not, by itself, an exposed secret.
05Do you only check security?
We can also examine bugs, slow queries, tests, code structure, backups and deployment steps. We agree on what to focus on.
06Can you fix the issues you find?
Yes. We can include a Fix Sprint: we agree on the changes, we implement them in your repository and re-test the affected features.
07How do you check whether the product can handle more users?
We examine expected operations, data volumes and the behaviour of queries and services. If load testing is needed, we agree on an environment and workload. Capacity estimates depend on those measurements.
08Do you work on products already in use?
Yes. We can start with an error, a slowdown or rising costs. Before making changes, we plan how to test them and limit disruption to customers.
09Will you need repository access?
Not for the first conversation or Quick Check. For a code review, we agree on the required access and confidentiality arrangements. We can arrange an NDA and remove access when the work is complete.
10How much does it cost, and how long does it take?
It depends on what you want checked or fixed and the size of the project. We propose the work, timeline and price before we start.
11Does the code have to be AI-generated?
No. We also review and fix software developed without AI.
12Can I launch if Quick Check looks good?
Quick Check examines a limited part of the public homepage. It doesn’t inspect code, internal permissions or signed-in workflows, and it doesn’t certify the product’s security. Those areas need a fuller review.
