As an experienced mobile and game developer with a specialization in PHP, I believe I am the ideal candidate for your software development project. With over 9 years of hands-on experience, I have successfully delivered countless projects on time and to clients' complete satisfaction. My proficiency in PHP and deep understanding of web technologies will enable me to create a robust software that seamlessly communicates with your PBX system through the AMI while leveraging the functionality of the Ultramsg gateway to send WhatsApp messages based on predetermined conditions.
Lastly, my combined skill set in mobile development (Flutter, React Native, Android Java & Kotlin, etc.), game development (Unity engine), block chain technology (NFT, ERC20), and AI engineering will contribute unique insights to our project. With my comprehensive understanding of different aspects of the tech world including secure communication channels via the Asterisk interface, we will be able to incorporate features like mass messaging from custom number lists effectively. Thank you for considering my bid; let's transform your software vision into an exceptional reality!
