I will fix angular or react bugs in your existing web application
Yehor I
About this gig
Is a bug blocking users or making your Angular or React application unreliable?
I diagnose and resolve focused frontend issues in existing web applications. With 6+ years of experience in production codebases, I work within your current architecture and avoid unnecessary rewrites.
I can help with:
broken components and UI behavior
TypeScript errors
forms, validation, routing, and state
responsive layout problems
frontend API integration errors
build or dependency issues
targeted performance investigation
My process:
1. Review reproduction steps, logs, and relevant code.
2. Identify the root cause and confirm scope.
3. Implement and test the fix.
4. Provide agreed documentation or code comments.
Packages cover only the number of related issues stated. New features, redesigns, backend development, major dependency upgrades, deployment, and unrelated bugs require separate agreement.
Please message me before ordering if the issue is intermittent, affects authentication or payments, depends on an external API, or does not clearly fit a package.

FAQ
Should I contact you before placing an order?
Please message me first if the issue is not clearly reproducible, spans several modules, involves authentication, payments, external APIs, performance, build failures, or a major dependency upgrade. A small, clearly scoped bug may be ordered directly.
What do you need to estimate the issue?
Please send a concise problem description, expected behavior, reproduction steps, screenshots or a recording, error logs, framework version, and relevant repository details. Do not send passwords, API keys, tokens, or other secrets in plain text.
How do you determine bug complexity?
Complexity depends on reproducibility, affected modules, root-cause uncertainty, third-party services, test coverage, environment differences, and whether frontend, backend, or deployment changes are required.
What counts as a revision?
A revision is a reasonable adjustment to the delivered fix within the originally agreed scope. A new bug, feature, redesign, extra platform, or changed requirement is additional work and may require an Extra or custom offer.
Are deployment and release included?
Deployment is not included in the packages unless agreed in advance. I can assist after reviewing your hosting, CI/CD process, environment, and access requirements. Platform or hosting approval cannot be guaranteed.
Can you work with existing or legacy code?
Yes. This Gig is specifically for existing Angular or React codebases. I will review the relevant area first and make focused changes without rewriting unrelated parts of the application.
Will you need access to my repository or systems?
Usually I need the relevant source code and enough information to reproduce the issue. If environment access is necessary, share it only through Fiverr-approved methods, grant the minimum permissions required, and use temporary or revocable access where possible.
How do you handle confidential information?
I use only the information required for the agreed task and keep communication and file exchange within Fiverr. Please remove unrelated personal data and never place passwords, tokens, private keys, or production secrets in messages or source files.
What if my issue does not fit a package?
Send the details before ordering. I will clarify the scope and recommend the closest package or explain why the task needs a custom offer. I will not treat an unclear request as unlimited work.
Can you send a custom offer?
Yes. A custom offer is appropriate for several unrelated bugs, cross-application work, major upgrades, backend changes, deployment assistance, or an investigation whose scope cannot be represented accurately by the packages.
