If they say that this is not possible, ask "Why?". It will be done. Should be. This is my motto. Nothing is impossible. For more than 5 years I have been engaged in mobile development and therefore I can definitely find a way out of any situation. I will be able to tell you the best and most daring solution of any problem. Together, we will develop an application that will be successful. Just choose what you want. Android? Maybe based on Kotlin or Java. I'll help you choose what's right for your app. Are you looking for an IOS developer? Not a problem I'll use Swift for that. Make your choice and leave the rest for me. Three important things for me: timing, quality and stability. I'm sure this is what you are looking for for your projects. So, I'm waiting for you. Contact me at any time and I will answer all your questions. Good luck!
