FAQ
Do we need to have a live meeting or video call for this service?
No. This service is 100% asynchronous to respect your time and project flow. All communication happens via Fiverr chat, and your deliverables will be sent as clear code updates and a detailed Markdown report.
What do I need to provide to get started?
You just need to share a brief context of your project goals, your current pain points (performance, bugs, readability), and access to your codebase (GitHub/GitLab repository or compressed files).
Can you review and refactor code written in languages other than React/Node?
My absolute expertise and focus are on the JavaScript/TypeScript ecosystem, specifically React, Next.js, and Node.js. This ensures you get a high-level, specialized architectural review.
