# fix, optimize, and explain your lovable, replit, windsurf or ai app

Your AI app works until it doesn’t

You shipped fast using tools such as Lovable, Cursor, or Replit. It felt smooth at first but now you’re hitting bugs, ballooning API bills, and unexplained behaviour. Suddenly you’re stuck debugging AI-generated code at 2 a.m., and the forums aren’t helping

Zinn Digital® is a senior full-stack developer and former CTO based in London, England. We’ve built production AI tools from scratch, scaled MVPs to real users, and integrated with everything from **Gmail**and **Stripe**to **OpenAI**and **Supabase**.

We don’t just fix problems—we explain what broke, why it happened, and how to prevent it next time. Think of us as your technical co-founder, not a code monkey.

Here’s what we can do for you: fix bugs in Cursor or Lovable apps, clean up AI-generated messes, reduce token usage, improve prompt reliability, and build scalable features. We also handle integrations—Google Calendar, Airtable, custom CRMs—and deploy to Replit, Vercel, or your stack. Whatever’s breaking, we’ll get it working and make sure it stays that way.

Every order includes clean code, a comprehensive walkthrough (Loom or written), and up to five days of post-delivery support.

Message Zinn Digital® to get your AI app back on track fast.
