FAQ
Do I need to provide my own hosting and domain?
Yes, the client is responsible for hosting and domain costs. However, I can provide expert guidance on choosing the best provider (like Vercel, AWS, or Netlify) and handle the initial setup for you.
Will I receive the complete source code?
Absolutely. Upon project completion, you will receive 100% of the source code developed in React, Node.js, or TypeScript. The code is yours to keep, and I ensure it is clean and well-documented for future updates.
Can you integrate third-party APIs into my application?
Yes, I specialize in complex API integrations. I have extensive experience fetching and displaying real-time data, as demonstrated in my Valorant Stats Tracker project. Whether it’s payment gateways, social media, or custom data feeds, I’ve got you covered.
What if my project requirements don't fit into the standard packages?
Every project is unique, like my work on AmbieGen. Please contact me before placing an order; I will analyze your specific needs and provide a custom quote tailored to your business goals.
Will my web application work on mobile devices?
Yes. I use modern frameworks like Tailwind CSS and React to ensure your application is fully responsive and provides a seamless user experience across smartphones, tablets, and desktops.
