Chi sono
I help founders rescue and stabilize AI-built web apps and backend systems. I diagnose deployment failures, Supabase Auth/RLS problems, API and database bugs, and Spring Boot issues, then deliver tested fixes with clear handover notes. My stack includes Lovable, Bolt, Replit, React, Vite, Supabase, Vercel, Java, Spring Boot, REST APIs, PostgreSQL, MySQL, Redis, and n8n. With 8 years of backend experience, I focus on root-cause analysis, secure access, clear scope, and practical fixes without unnecessary rebuilding.
