Sebastian
About this gig
Get your Next.js, React or TypeScript app back on track with fast turnaround and maintainable code. 1-day delivery requires agreed scope, complete requirements and working access.
INTRODUCTORY PRICING
- $25: 1 small reproducible bug
- $60: 2 small agreed bugs
- $120: up to 3 small scoped issues
One existing app. Unlimited revisions within the original agreed scope; new requests need a separate quote.
I CAN HELP WITH
UI/mobile bugs, TypeScript errors, broken components, existing API issues and scoped build/runtime errors.
HOW I WORK
I reproduce the issue, make a focused fix, run relevant available tests/checks and explain the changes. Regression tests where practical within scope; full test-suite setup is separate.
Use temporary minimum-permission repository/test access. Keep production secrets out of chat and samples.
No rewrites, new products, security audits or unlimited debugging. Hosting and third-party fees are separate. Architecture changes or external-service issues may need a custom quote.
Message me on Fiverr before ordering with reproduction steps, errors, versions and relevant code to confirm scope and delivery.
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.

FAQ
Can you guarantee that every bug is fixable in a package?
No. Please message me with reproduction steps first. I confirm scope before accepting a package. Architecture changes or issues caused by external services may require a custom project.
What access do you need?
A repository invitation or a minimal reproduction, setup instructions, and test credentials if needed. Use temporary access with minimum permissions. Do not send production secrets.
Do you include tests?
I run relevant available checks and explain the verification. A focused regression test is added where practical within the agreed scope. Setting up an entire test suite is separate.
What is included in the revision?
Unlimited adjustment rounds to the original agreed deliverable and acceptance criteria. New features, unrelated bugs, additional sections, workflow steps or integrations, redesigns and expanded scope require a separate quote.
