FAQ
Why choose an engineer for Vibe Coding?
AI tools like Lovable and Base44 create fast UIs, but they often produce backend bugs, broken auth, or security issues. As an experienced full-stack developer, I use AI for 10x speed while ensuring your database, logic, and APIs are stable and production-ready.
What if my Lovable or Bolt app already has errors?
Choose the Basic or Standard package. Send me your project link or GitHub repository, and I will debug the code, fix the errors, and deploy it smoothly on Vercel.
