NOW BOOKING · MAY 2026 RIVETZ // LOVABLE + SUPABASE SECURITY SPECIALIST_
LOVABLE + SUPABASE SECURITY SPECIALIST

Your Lovable app works.
Until real users touch it.

91.5% of AI-built apps have at least one critical vulnerability (Q1 2026 research). Automated scanners flag the obvious ones. Rivetz finds what they miss, then fixes it at a fixed price. No report-and-leave. CVE-2025-48757 (CVSS 9.3) hit 170 Lovable apps in a single weekend. Async only. 14 days.

The pattern

Lovable shipped your app. It didn't ship your security.

Automated scanners (including Lovable's built-in scanner and paid tools) catch what they can verify from the outside. They don't catch the things that cost founders real money: the RLS policy that looks correct but fails on multi-table joins, the Stripe webhook that trusts unsigned payloads, the AI endpoint burning $2,000 overnight with no rate limit.

Most security services give you a report and leave you to figure out the fixes. We find the issues, then fix them. Fixed price. No hourly billing. No scope creep. No live calls.

91.5% of AI-built apps have at least one critical vulnerability (Q1 2026 research). CVE-2025-48757 (CVSS 9.3 Critical) exposed unauthenticated database access across 170+ production Lovable apps in a single weekend. Martin Fowler published on this today: "Telling an AI agent to be safe is not the same as enforcing that it is safe."

"CVE-2025-48757: Insufficient Row-Level Security policy in Lovable allows unauthenticated access to any database table. Severity: 9.3 Critical." NIST National Vulnerability Database, May 2025
"Woke up to a $2,400 bill. Someone had been looping my AI endpoint overnight. Nothing I could do — charges had already cleared. I didn't know rate limiting was something I had to add myself." Lovable community, 2025
"A user reported they could see other customers' data. Supabase RLS had been off the whole time. Lovable never mentioned it. I didn't know it was a setting I needed to configure." Lovable community, 2025
First result
Jace flagged 3 security issues in my app I had no idea about, just from reading my public code, and told me exactly how to fix them. All free.

The work

Three days. Then you know exactly what's wrong.

01 / DISCOVERY

You send the repo

GitHub access or a Lovable share link. I clone it, read it, and run it. No 30-minute kickoff call. No proposal back-and-forth.

02 / AUDIT

I tear it apart

Security scan, code review, database review, deploy review. I find what's exposed, what's brittle, and what will break first when traffic hits.

03 / DELIVERY

You get the report

A prioritized fix list. A Loom walking you through every finding in plain English. Async Q&A so you can ask anything in writing. Re-readable, no calendar tag. Three days, start to finish.

Fit check

This works for some founders.
Not all of them.

// good fit

  • Built a working Lovable app, has early users or is about to launch
  • Knows something is wrong but can't articulate exactly what
  • Wants a flat fee and a finish line, not an hourly billing relationship
  • Can describe their product in plain English even if they can't read the code
  • Treats $1k to $5k as a real but acceptable investment to protect what they built

// not a fit

  • Hasn't shipped anything yet and wants help building from scratch
  • Wants a $200 quick fix and doesn't see the value in a proper audit
  • Has a funded startup with a CTO who should already be doing this work
  • Expects me to take over the product roadmap or run their company
  • Needs HIPAA, SOC 2, or other heavy compliance work (different specialty)
Jace Alfeche, founder of Rivetz
// the operator

Who's actually doing the work.

I'm Jace. I build with Claude Code daily. I've shipped real products, run marketing for a small business, and spent the last year deep inside the AI-builder ecosystem.

I'm not a Big Tech engineer slumming it. I'm not a Fiverr shop in another timezone. I'm one person who understands both sides: I know what it's like to vibe-code an MVP, and I know how to make that MVP not embarrass you when real people use it.

You'll talk to me. I'll do the work. If it breaks, I'll fix it.

Common questions

The obvious things people ask.

Why not just use Lovable's built-in "fix" button?

Because you've already tried it. The fix button works for visible bugs the AI can identify from logs. It doesn't catch missing auth checks, exposed API keys, weak input validation, or architectural issues that bite you under real load. The fix button is great for typos. It's not great for production readiness.

Couldn't I just hire a $50 Fiverr developer?

You could. Most founders try this first. The pattern is: they patch one bug for $200, three new ones appear, they hire someone different, and six weeks later they've spent more than this audit costs and the codebase is in worse shape. I'm not the cheapest option. I'm the one you call after the cheap option doesn't work.

What if my app is built on Bolt, Replit, v0, or Cursor instead?

Right now I'm specializing in Lovable specifically because the platform has the highest concentration of non-technical founders who need this work. If you're on a different builder, email me anyway and we'll figure out if it's a fit. The principles are the same.

How do I know I won't get a useless report?

Before you pay, I'll do a free 15-minute scan of one specific thing in your app and send you a Loom. If that Loom is useless, the full audit will be too, and you'll know before spending a dollar. If it's useful, you'll see what the full report looks like.

What if you find something that needs a full rebuild?

I'll tell you straight. If your app genuinely needs to be rebuilt, the audit will say so, and I won't try to sell you a cleanup that's actually a rewrite. In that case I'll point you to people who handle that kind of work and you'll have a clear, honest assessment to take to them.

Do you sign an NDA?

Yes, mutual NDA before any code changes hands. Standard.

Your app deserves
to not break.
