Reply within a day
Send me the link, or a few lines about what you want to build. I'll reply within a day with honest next steps, even if I'm not the right fit.
Step 1
You send a link or an idea
A few lines is enough.
Step 2
I reply within a day
With questions or a first take.
Step 3
A free 30-minute call
Then a fixed price, in writing.
(01) App rescue
Your app works in the demo, and every new prompt breaks something. I read the code, close the security holes, fix what breaks and get it ready for real users, without starting again. Apps built with Lovable, Bolt, Cursor and v0, on Supabase, Firebase or Next.js.
(02) Sounds familiar
A bug comes back a week after it was fixed, or a change to one screen breaks another.
Real users are about to sign up, and you don't know who can read whose data.
Orders sometimes aren't marked paid, or you can't say what happens when a payment fails halfway.
A developer looked at the code and suggested starting again. You'd rather not.
(03) The audit
Supabase row-level security or Firebase rules, read against who should see what, then tested from outside.
Every key: where it lives, who can read it and what it can do. Secret ones belong on the server.
Every API route, Edge Function and Server Action checks who is asking before it acts.
Orders marked paid only by signed webhooks, and safe when the same event arrives twice.
Sign-up, the core action and payment, end to end, including the ways they fail.
Copied logic, giant files and types switched off: where changes break things, and why.
A staging copy, a deploy you can repeat, and errors that reach you before users do.
How it loads on a mid-range phone, and whether Google can see the public pages.
You get every finding with what it means for your business, how to fix it and a rough estimate in hours, plus fix or rebuild for each area. The report is yours: take it to any developer, including your own.
(04) How it works
S/01Audit
I read the code and the database, test the live app and write up what to fix first.
$500 – $1,500
Fixed price by app size, report in 3 to 5 days.
S/02Fix
I fix it in order of risk on a staging copy, with notes so you can keep building with your AI tool.
$1,500 – $6,000
Quoted from the audit, fixed before I start.
S/03Keep it healthy
If you want, a monthly plan for fixes, updates and small features after launch.
From $800 / month
Automations watched and tuned, plus fixes and updates. Cancel any month.
(05) Proof
In about six months on Unlok Insights, a production codebase with 16 AI agents and a team of interns.
Unlok InsightsI built the Unlok app for US stocks and ETFs as its only mobile engineer, and took it through App Store and Google Play review.

(07) Questions
Yes. The code these tools write is ordinary React, Next.js and Supabase or Firebase, and that's what I work in every day. I start with an audit, so we both know what's wrong before you pay for fixes.
Only the parts that need it, and only if the audit shows they do. Most AI-built apps need fixing, not rewriting: the data model is usually sound and the problems are at the edges.
The audit is $500 – $1,500, fixed by the size of the app, with the report in 3 to 5 days. The fixes are quoted from the audit, usually $1,500 – $6,000, and fixed before I start.
Read access to the code repository and the backend (Supabase, Firebase or similar), and a test account on the live app. I sign an NDA before you share anything, if you want one.
Yes. I keep the structure your tool already understands and leave notes on what changed and why, so you can keep prompting without undoing the fixes.
No. I take rescues case by case, after a free call, when I think I can fix the app without a rewrite. If I can't help, I'll say so on the call.
Something I haven't answered? Put it in your brief, or email me. I reply within a day. HS is one person, so the person you talk to is the one doing the work.
