I will fix one website or web app bug and provide a tested patch

I will investigate and fix one clearly defined bug in your website or web application.

What is included:

• reproduce and identify the root cause
• implement a focused fix
• add or update a regression test where practical
• verify the affected workflow after the change
• provide a short explanation of what was wrong and what was changed

Suitable for:

• JavaScript / TypeScript issues
• React frontend bugs
• Node.js / API problems
• form and validation errors
• broken integrations
• data-processing issues
• responsive UI bugs
• small automation or scripting problems

Please send:

• a clear description of the issue
• expected vs actual behaviour
• relevant code or repository access
• steps to reproduce the problem

This service is for one small, isolated bug. Larger features, full redesigns, smart-contract audits and major architecture changes should be quoted separately.

I use AI-assisted development together with manual review and testing. No production changes are made without the client's approval.
