A free review of your code.
Give read access to the repo. I go through what makes changes risky: how the code hangs together, whether anything tells you when something breaks, and how a new version goes out. You get a written answer within two working days.
What I look at
What usually decides it.
Structure
Whether you can find where things happen, and whether a change in one place has consequences in three others.
Tests
Whether anything tells you when the important things break — sign-in, payments, data — before a customer does.
Dependencies
Old packages and frameworks with known security holes, and how far behind they are.
Secrets and permissions
Keys in the code, permissions that are too broad, and who can reach production.
Deployment
How the code goes out, whether it can be rolled back, and whether anyone but you can do it.
What makes changes scary
What a new developer would need to know first, and that today only lives in someone's head.
How it works
Three steps, no meeting.
- 1
Send a link
To the website, app, prototype, code or quote — and a sentence about what you're wondering.
- 2
I go through it
On my own, without you having to demo anything in a meeting. If I need access to something, I ask first.

You get a written answer
Within two working days: what holds up, what doesn't, and what I would do first.

“I have had the privilege of working with Ketryon for several years, and my experience has been consistently excellent. Their professionalism, reliability, and dedication to delivering high-quality results have made them a trusted partner. Ketryon combines strong expertise with a solution-oriented approach, which has greatly contributed to the success of our projects. I highly value their commitment, responsiveness, and ability to adapt to our needs. I can warmly recommend Ketryon to any organization looking for a dependable and competent partner.”Does it cost anything?
No. The review is free, and you don't have to buy anything afterwards.
How quickly do I hear back?
Within two working days of receiving the link.
Who does the review?
Kenny Tran, the developer who runs Ketryon. Not a salesperson and not a tool.
What happens next?
Nothing, unless you want it to. If you'd like someone to do what the answer says, the subscription is there — but the answer should be usable without it.
