FAQ
What technologies do you work with?
I specialize in the entire JavaScript/Node.js ecosystem including Node.js, Express.js, React.js, Next.js, Nestjs, Electronjs, TypeScript, MongoDB, PostgreSQL, MySQL, Firebase, Redux, REST APIs, and more.
Do I need to provide access to my repository?
Yes, to work on your Node.js, React.js, or Next.js project efficiently, I'll need access to your code. Your code and project details will be kept completely confidential. I can also sign an NDA if required for sensitive projects.
What if my issue is more complex than expected?
No problem! After reviewing your requirements, if the task is more complex than the selected package, I'll communicate with you immediately. We can either adjust the package or create a custom offer that fits your needs. I always aim for transparency and will never deliver incomplete work.
Can you work on existing projects or legacy code?
Absolutely! I have extensive experience working with existing codebases, including legacy Node.js and React projects. Whether your project uses older versions or has complex architecture, I can jump in, understand the code structure, and make the necessary improvements or fixes .
Will you provide documentation for the changes made?
Yes! with additional offer, I provide clear code comments explaining the changes. For Standard and Premium packages, I also include documentation describing what was modified, added, or fixed.
What if I need ongoing support for my Node.js or React.js project?
I'd love to support your project long-term! For ongoing maintenance, feature additions, or continuous development, we can discuss a monthly retainer or project-based arrangement.
