You built with Lovable, Bolt, Cursor, or Supabase and it runs. The part nobody checked is whether strangers can read your users data, whether a real login holds, and whether payments actually settle. I am the senior engineer who verifies that, fixes what is wrong, and tells you straight when it is safe to ship.
Your money and data path, verified. Not assumed.
Every model ships more code for people who understand it less. The gap between what runs and what someone checked only gets wider. That gap is the work.
I scanned 500 live AI-built apps. 177 run on Supabase; 1 in 6 of those had a database table anyone could read with no login, and 0 leaked a full-access key.
Public data only, one harmless read per table, nothing kept beyond the counts. This is the exact failure I verify and close before your customers find it.
See the full scan and method →I hired Matt to take over a challenging app development project left in disarray by a previous developer. He not only cleaned up the messy code but also completely transformed the app, enhancing its functionality and elevating the user experience (UX) and design to an exceptional level. Matt's rare combination of strong coding skills and design expertise set him apart. His calm demeanor and ability to explain solutions clearly and logically made the process smooth and stress-free. I highly recommend Matt for any app development project.
Matthew provided guidance and expertise to make sure that my repo was solid and ready for launch. He was always available and worked extremely well with me given our remote environments, I would highly recommend Matthew for anyone trying to launch a new digital app/platform with the need for a highly skilled engineer and developer.
More than 20 years building and shipping software.
Give me your app URL and I run the common public-exposure checks from the outside, then send you one concrete finding. It is the same first look I start every verification with. Free, and the result is yours whether or not we ever talk.
If you recognize one of these, the app is not hopeless. It usually means the AI tool got you something that runs, and nobody has checked the part that actually protects your customers and your money.
Missing or wrong row level security, tables left open, admin keys sitting in the browser. This is the one that ends businesses, so it goes first. I check whether a stranger can reach your users data, close the hole, and prove it with real tests.
Sign-up loops, magic links that expire, sessions that drop, roles that do not stick. I trace it through the auth provider, the redirects, and the code that trusts the wrong thing, and verify a real user can actually get in and stay in.
Stripe checkout that succeeds with no order, webhooks that never land or land twice, subscriptions that drift out of sync with your database. I verify money and records agree, and keep agreeing, not just on the day you tested it.
An agent with write access to production is one bad instruction away from wiping a table or rewriting rows nobody asked it to touch. I check what moved, put guardrails and real backups in place, and confirm the data you depend on is still there.
A build-time tool does not run in your production next month. Quietly failing payments, an integration that started returning errors, an exposure that opened after a change. I verify it is still safe and still charging correctly, long after the demo.
The developer left, the plugin stack is a pile, the repo has no docs. I read it, work out what is safe to touch, verify what is actually at risk, stabilize it, and leave it documented for whoever comes next.
You are not a developer and should not have to become one. You shipped something real with an AI tool, and now you need someone senior to verify the logins, the data, and the payments actually work, fix what does not, and tell you straight whether it is safe to put in front of customers.
Agencies, if an AI-built client project needs a verification pass or a second set of senior eyes, send me the overflow. White-label friendly. How that works →
I go through the code, the database, the hosting, and the third-party accounts before I change anything. You get a plain-English account of what is actually wrong and what it puts at risk.
Data exposure, money problems, and broken auth come first, with a way to roll back before I touch anything that matters.
Then the rest of the list, in the order that lowers your risk fastest, with real tests behind it, until it is something you can ship and keep running.
You own the repo, the accounts, and the keys. It is written down so you, an in-house hire, or another developer can pick it up without me.
You work with the engineer who does the work. No account manager, no junior handoff, no ticket queue between you and the fix.
The goal is a verified, working product you can ship, not a PDF that lists forty issues and leaves you to it. I close the problems and hand it back done.
Their trust is your business. I treat exposed data and leaked keys as emergencies, and I tell you plainly the moment I find one.
If you are not technical, you do not need to be. I will tell you what is broken, why, what it costs to fix, and what happens if you wait.
Want a fixed-price starting point? Ship Check reads the code and tells you what is wrong. Ship Fix is the fix, quoted up front.
Yes. Most people who reach out built with an AI tool and are not sure what is safe. You describe what you have in your own words, and I translate it into what is actually working, what is not, and what to do about it.
I check the things an AI builder does not check for you. Can a stranger read your users data. Does a real login hold. Do payments settle and match your records. Did the data survive. I prove it with real tests, not a scan that spits out a list, and then I fix what fails.
It depends on the size of the app and how deep the problems go, so I do not quote blind. The first call is free. After I have looked, scope and price are agreed in writing before work starts. If you want the published ranges, Ship Check and Ship Fix show them.
Only if that is genuinely the cheaper, safer path, and I will show you why. Usually it is not. I fix what is costing you and leave the rest alone.
The repository, the hosting and database accounts, and any third-party dashboards involved. I ask for the least access that gets the job done, and everything stays under your ownership.
Yes. If an AI-built client project needs a verification pass or a second set of senior eyes, send it over. White-label and NDA-friendly is normal, and your client relationship stays yours.
A 30 minute call is enough for me to hear what you have and say plainly whether I can help. No pitch deck, no obligation. Prefer to write it out? Email works just as well.
