I help founders launch safer AI-built apps
I’m Jessica Denkelaar, a Senior Web Developer for 20 years, who builds products with AI and helps non-technical founders turn vibe-coded prototypes into secure, launch-ready products.
// what I do
Most vibe-coded apps are demo-ready, not launch-ready.
They look great on video, but launch with:
I help you move from demo-ready to launch-ready by:
✓reviewing auth, data access and critical flows,
✓finding hidden launch blockers, and
✓giving you a clear, prioritized fix plan you can implement with your AI tools.
// who this is for
This is for you if:
→You built your app with AI tools like Cursor, Lovable, Bolt, Replit, or v0.
→You’re 1–4 weeks from launch or just launched.
→You want to invite real users without silently leaking data or breaking things.
This is not for you if:
—You don’t have a working prototype yet.
—You want a generic certificate without changing anything.
—You’re looking for the cheapest possible pen test.

In one week, you’ll get a clear answer to a simple question:
