I want to create a text messaging app? Something like whatsapp

I am looking for someone to develop a text messaging app for me that is compatible with both iOS and Android. The app should include voice/video call functionality and be completed within 3 months. An ideal candidate would have experience developing apps, and have a good understanding of coding languages for both iOS and Android. If you feel you are the right match for this project, please get in touch. I look forward to hearing from you.
