    Dear my Valued Customer, I'm a full-stack software developer. I'm your one-stop-shop. You can get me to build your Backend, Restful APIs, NodeJS Backend, NestJS Backend, web apps, MERN stack web apps, MEAN stack web apps, native iOS apps, native Android apps, React Native apps, Kotlin, Flutter, Unity, Python and even C# apps. All apps will be made carefully and perfectly by following a strict timeline. You can see things done week by week. If you have time, you can discuss closely with me every single detail of your apps. But, I only charge you a reasonable price. I'm open to any negotiations. So feel free to ask for some discount if it makes you feel more comfortable. I hope we will have a long-term working relationship. And I wish you all the best with your business plans. Best regards, Nhan Nguyen.
