My Portfolio
FAQ
Do you provide the complete source code and ownership?
Yes, absolutely. Upon project completion and payment, you will have 100% ownership of the source code. I will transfer the repository via GitHub or GitLab, including all necessary documentation for future maintenance.
How do you ensure the security and scalability of the application?
I follow industry-standard security protocols, including JWT authentication, data encryption, and protected API routes. For scalability, I architect the backend using Node.js/Express and optimized databases (PostgreSQL/MongoDB) to ensure the system can handle thousands of concurrent users seamlessl
What is your delivery process?
I usually deploy it after my work is done and give a live preview link. Where you give me feedback if any change is needed. Once everything is fixed I deliver the order with source code.
What If I don't have any idea about websites and website designs?
I am here to facilitate you at every single step. If you don't have any idea then I will provide you some website templates and you have to select from them considering your business in mind. Or I will help you choose a design and I will make the website on that design.
If I have a website as a sample. Can you develop a website exactly the same way?
Yes, I will develop the website exactly in React and Node js like your sample website in such a way that you yourself cannot make a difference between them.
What should I do after ordering your Gig?
You should text me after ordering Gig and I will communicate with you about your demands and then I will start working.
What I have to provide you before starting working on the project?
You will have to provide me the full overview of your Business + website design if you have + Business Logo + Color Combinations that you want in website + Domain and Hosting information and that's all
What If I don't have Logo and Domain/Hosting?
Don't worry at all. I am here for you. I will make a logo for your website but I will charge some extra amount for this. I will also buy the domain and hosting for your website if you haven't purchased yet but I will charge an extra amount for that depending on their time period.
How will I receive my website after project is complete?
I will provide you the link to the website and then you will be able to check your website fully. I will also provide you the source code of your website in the form of a Github repo from where you can download or clone your code files.
Is mobile responsiveness included in all packages?
Yes, all my web applications are mobile-first and fully responsive across all devices (Mobile, Tablet, Desktop) as part of the standard service.
