01
Code & security audit
A full review of your codebase, database rules, authentication and infrastructure. You get a plain-English written report that ranks every issue by risk and explains what to fix first.
Prototype → Production
From working prototype to profitable product.
You built it with Lovable, Bolt, Replit or another AI tool, and it works. I find the bugs and security gaps, harden the foundation, and get it ready to take real customers and real payments.

The gap
The prototype proved the idea. Now it has to survive real users.
AI builders are excellent at getting an idea working fast. They are not designed to make the decisions that keep customer data safe, payments reliable, and a codebase maintainable as it grows. That's where an experienced engineer comes in.
01
Security
Open database policies, exposed keys, and missing server-side checks put your users' data, and your business, at risk.
02
Reliability
Bugs that only appear with real traffic, edge cases nobody tested, and fixes that break something else.
03
Revenue
Payments, subscriptions, onboarding and analytics that have to work every time before you can charge with confidence.
Services
Everything between “it works” and “it's a business.”
02
Security hardening
Lock down row-level security, move secrets server-side, validate every request, and close the gaps that AI-generated code tends to leave open.
03
Bug fixing & stabilization
Track down the bugs that keep coming back, fix root causes instead of symptoms, and add tests so fixes stay fixed.
04
Production infrastructure
Proper hosting, a staging environment, automated deploys, error monitoring and backups, so you know about problems before your customers do.
05
Payments & growth features
Reliable Stripe checkout and subscriptions, user accounts and roles, transactional email, analytics and SEO: the features that turn users into revenue.
06
Ongoing engineering
Once you're live, keep an engineer on call for new features, updates and fixes, without hiring a full-time team.
Process
Keep what works. Fix what doesn't.
Your prototype already does the hard part: it proves people want it. I build on that foundation instead of starting over, and only rebuild the pieces that genuinely need it.
Step 01
Audit
I review your code, data and setup, then deliver a written report ranked by risk.
Step 02
Roadmap
We agree on a prioritized plan with a fixed scope for each milestone, so there are no surprises.
Step 03
Harden & ship
I fix, secure and deploy in stages, with progress updates you can actually follow.
Step 04
Hand off or keep going
You own all the code and documentation. Continue on your own, or keep me on for what's next.
About
You work directly with the engineer.
I'm Amanda Yonce, a software engineer and the founder of Second Nature Software. I've built and maintained production software for years, including real-time platforms where reliability isn't optional.
No account managers and no hand-offs. The person who reviews your code is the person who fixes it, and you'll always know where your project stands, in plain language.
Based in Camden, South Carolina. Working with founders and small teams everywhere.
FAQ
Common questions
Will you rewrite my app from scratch?
Usually not. Most prototypes have a solid core worth keeping. I recommend rebuilding a piece only when it costs less than repairing it, and I'll show you why.
Which platforms do you work with?
Apps generated with Lovable, Bolt, Replit, v0 and Cursor, and the backends they commonly use, including Supabase and Firebase. If your app was built another way, ask.
Can I keep using my AI builder afterward?
In many cases, yes. I'll tell you which parts are safe to keep editing with AI tools and which should go through review.
Who owns the code?
You do. All code, accounts and documentation stay in your name from day one.
What do you need to get started?
A link to the app and a short description of what's going wrong or what you want to launch. I'll follow up to arrange access to the code.
