Done! Your app is live.

Senior code, security and architecture review for apps built with Lovable, Bolt, Cursor, Replit and v0. From an engineer who has spent 16 years building systems in fintech, iGaming and cyber security, where downtime costs real money.
20 minutes, free. Bring your repo link.
AI tools are brilliant at making things work. I check the parts they tend to skip: the ones that decide whether your app stays safe, reliable and affordable once real users arrive.
Security. Exposed API keys and secrets, open endpoints, injection risks and the OWASP Top 10, checked against how your app actually works.
Login and permissions. Sign-up, login and password reset, sessions, and whether every user can only see their own data.
Database schema. Tables, relationships, indexes and constraints, row-level security, migrations and backups.
Privacy and compliance. How you store personal data, GDPR basics, and keeping card details out of your systems entirely.
Code quality. Structure, duplication, error handling and the shortcuts AI tools leave behind. Could a developer you hire next month work with it?
Repository setup. Branch protection, environment files, pinned dependencies, and secrets committed by mistake.
CI/CD and tests. Automated builds, tests and deploys, so nothing goes live without passing checks and every release can be rolled back.
Payment provider best practices. Prices set on the server, verified webhooks, no double charges, refunds and failed payments handled the way Stripe (or your provider) intends.
Vendor lock-in. How tied you are to Supabase, Firebase, Vercel or your AI builder's hosting, and what it would take to move.
Running costs. Cloud, database and AI API spend at ten times today's usage, and where the bill is likely to surprise you.
Architecture. How the pieces fit together, where the single points of failure are, and what to simplify.
Infrastructure. Hosting, regions, environments and disaster recovery, sized for where you are now.
Monitoring. Error tracking, logs, uptime checks and alerts, so you hear about problems before your customers do.
Performance, scaling and system design for your next stage of growth come with the Architecture & Scale Plan.
20 minutes, free. You tell me what you've built, who it's for and when you want to launch. I recommend the right review and give you a fixed price.
You give me read-only access to the repo and hosting. I work through the full checklist: security, data, code, delivery, payments and infrastructure. Usually 5 to 7 business days.
A written report with every issue ranked by severity, explained in plain English, with the exact fix. Then we go through it together on a 60-minute call.
Fix the issues yourself with your AI tools (the report includes prompts you can paste in), or hand it to a developer. On the Architecture & Scale Plan, I re-check the critical fixes before you go live.
Most founders start with the Launch Readiness Review: a fixed price for a fixed scope. Larger engagements are quoted after the fit call, because they scale with the size of your project.
Start here
$1,200(fixed)
For: an MVP about to go live or start taking payments.
from$3,500
For: products expecting real traffic, or heading into a fundraise.
from$3,000/ month
For: non-technical founders who need a senior engineer on call.
All prices in USD. Not sure which you need? That's what the fit call is for.
I've been a software engineer for 16 years, building systems where failure is expensive: real-money gaming platforms that can't go down on a Saturday night, payment systems that move other people's money, and security products that get attacked for a living.
Now anyone can build an app in a weekend, and that's brilliant. But the parts AI tools skip (security, data integrity, scaling, what happens at 3am when it breaks) are the parts I've spent my career on. I review your app the way I'd review a system I was about to be on call for.
Download a complete example report for Moveslot, a fictional class-booking app built with Lovable, Supabase and Stripe. 12 findings ranked by severity, each with a plain-English explanation, the fix and a prompt for your AI tool.
Download the example report (PDF)Anything built with Lovable, Bolt, Cursor, Replit, v0, Claude Code or similar, and the stacks they produce: React, Next.js, Node, Python, Supabase, Firebase, Postgres, Vercel, AWS and more. Not sure? Ask on the fit call.
I sign your NDA, or send mine, before seeing anything. I only need read-only access, and you can revoke it the moment the review is done.
The Launch Readiness Review usually takes 5 to 7 business days from repo access to report. If you have a hard launch date, mention it on the fit call.
The report gives you the exact fix for every issue, including prompts you can paste into your AI tool. If you'd rather I make the changes, I'll quote for that separately.
Then you launch with evidence that your app is solid, which is worth showing investors and customers. It's rare for a first review of a vibe-coded app to come back clean.
Yes. The Architecture & Scale Plan and Fractional Tech Advisor both include preparing for technical due diligence, so the questions investors' engineers ask don't catch you out.
20 minutes on video. Tell me what you've built and when you want to launch, and I'll recommend the right review with a fixed price. No obligation.
