I will diagnose and fix bugs in your web app
Simon L
About this gig
Your AI-built app looks promising but a bug is blocking progress? I help founders diagnose and fix reproducible issues in React projects, including apps started with Lovable or Bolt. The goal is a clear, testable correction with an explanation you can use.
Please share the symptoms, stack and expected behaviour before ordering. I confirm whether the issue fits a fixed package. Delivery includes the agreed code changes, verification notes and a short handoff. Supabase or deployment work is included only when explicitly scoped.
Please read the package scope and send your brief on Fiverr if your project needs clarification. Revisions refine the agreed scope; new features and third-party fees are separate.
Respect third-party rights
Please be aware that it is against Fiverr's policies for sellers to include themes, templates, or any other elements that infringe third-party rights or applicable laws in the delivered work. Read more about in our Guide to Responsible Digital Creation.

I'm Simon, founder of Ligne Studio in Paris. I design and build responsive websites, landing pages and web apps, from Figma UX UI to React development. Need a focused fix? I also repair Lovable and Bolt apps, Supabase issues and deployment bugs, connect APIs, automate workflows and provide practical AI training. My work includes Dulac Cinemas, editorial experience at AOC and independent products such as Reelify. Small tasks, full builds and ongoing agency support are welcome. Expect clear scope, careful implementation and a documented handover. French and English. Tell me what you need.

FAQ
What is outside the scope?
A whole-app audit, rewrite, new feature, data recovery or security certification is excluded. If an issue cannot be scoped confidently, I propose a separately priced diagnostic first. No promise that every unknown bug fits a package.
Can you fix any app for the Basic price?
No. Basic covers one small issue accepted after review. Complex auth, database, infrastructure and multi-service issues need a wider scope.
What if you find a bigger underlying problem?
I explain the finding and propose options. Additional work requires an agreed scope; it is not automatically included.
Do you guarantee that the whole app is bug-free?
No. Verification covers the agreed issue and related checks, not all features or every possible environment.
What does a revision include?
One consolidated round of feedback on the agreed deliverables. New pages, features, integrations or a new direction require a separate scope.
Can we work in French?
Yes. I work in French and English. Project messages, files and arrangements stay on Fiverr.
Can you support a larger project?
Yes. We can define a custom offer or delivery phases with a written backlog, deliverables and acceptance criteria. Ongoing support is not included automatically.
What does each package cover?
Basic: one accepted frontend bug estimated at up to 1 hour. Standard: one accepted integration issue estimated at up to 3 hours. Premium: up to 8 hours on an agreed backlog. One codebase and environment. Please send reproduction steps before ordering so I can confirm the scope.
