About this gig

Your app was built fast with AI, but now it breaks, leaks data or nobody knows how to deploy it? We are software testers turned developers, and this is exactly the work we do every day.


What we fix:

  • bugs and broken flows (login, payments, forms, dashboards)
  • security holes: exposed API keys, missing access rules (e.g. Supabase RLS), unsafe inputs
  • slow pages, failing builds, deployment to Vercel, Netlify or your own server
  • messy code that the AI keeps breaking: we clean it up so you can keep building

How we work:

  1. You share the repo (GitHub, Lovable or Bolt export) and describe the problem.
  2. We send a written diagnosis with a fixed price before touching anything.
  3. Every fix is tested, and Standard and Premium include automated Playwright tests for your key flows.

Message us first with a short description, so we can confirm the scope.

We are VoxQuartz Systems, a small software company from Poland with roots in software testing. We build web apps and AI automations with Claude Code, n8n and the OpenAI and Claude APIs, and we rescue apps built with Lovable, Bolt or Cursor that stopped working or are not safe to launch. Every job starts with a written scope, price and date. You get tested code, a clear summary and full access. We work asynchronously through Fiverr messages, so everything agreed stays in writing. Send us what you need. We reply within 24 hours.
