Batista makes sure your AI-built app is production-ready. The tools that shipped it fast left flaws underneath, and flaws like these stay invisible until it's too late. Batista finds them first and ranks them by what they cost you.

Speed without review is debt with good marketing.

WHAT_IS_ACTUALLY_BROKEN // 03

AI writes code that works. It doesn't write code that holds up.

The pattern repeats across every vibe-coded codebase reviewed to date. Hardcoded secrets in client-side JavaScript. Authentication logic that trusts the browser. No input validation. Row-level security disabled or never configured. Duplicate functions spread across files with no shared convention. Zero test coverage.

The risk isn't that the app fails on day one. The risk is that it passes every demo, charges its first paying customers, then breaks under real load, a real attacker, or a real compliance check. By then the cost of fixing it has multiplied.

WHAT_I_DO // 04

SCOPE_01

A senior engineering review. Five business days. One report.

For founders who built their product with Cursor, Lovable, Bolt, Replit, v0, or Claude Code — and want to know what's actually underneath before the next user finds it.

DELIVERY_02

The audit covers four areas: security, code quality, scalability, and dependencies. You get a written technical report with severity-ranked findings, specific file references, and a prioritized fix roadmap. A 45-minute recorded walkthrough accompanies every report — so your developer or the next engineer you hire can act on it without you needing to translate.

OTHER_WORK // 05

Other engagements, in order of how often founders ask for them.

ARCHIVE_01

Custom audits and technical due diligence

For codebases past the vibe-coded MVP stage. Larger teams, more complex stacks, fundraising or acquisition contexts. Scoped individually. Starts at €4,500.

ARCHIVE_02

AI and automation

For founders and small teams who want to build internal tools, automate workflows, or integrate AI into existing products — without inheriting the same problems the audit was built to find.
