Audit Vibe coding - Hippodoc
Reviewed on 6/22/2026
I hired Alexandre to audit my app, which I developed myself with AI.
Alexandre was the only one who didn't suggest rebuilding everything. He took the time to understand my project, conducted a clear and very concrete audit, then delivered a prioritized action plan that I could actually follow.
He then leveraged his fullstack developer expertise to secure critical points, allowing me to launch with confidence.
Beyond the technical aspects, I appreciated his teaching and transparency: he explains his choices, challenges requests when relevant, and always remains available and responsive. We have since worked together again, and it's always as smooth.
I recommend him without hesitation.
