With over 12 years of experience working on full-stack web and app development, I am more than equipped to help bring your vision for a next-level messaging app into fruition. As an expert in Python, PHP, Laravel, CodeIgnitor, and multiple CMS frameworks like WordPress and October CMS, I have a wide skillset that can be tailor-made to fit the unique needs of your project. In fact, as a Zend Certified PHP Engineer, I have deep-rooted knowledge in delivering high-quality results.
One crucial aspect of your project that sets it apart is the emphasis on elevated security measures. I take data privacy very seriously and have hands-on experience with applied cryptography and building secure systems. This aligns perfectly with your need for end-to-end encryption to ensure user's privacy is adhered to.
Additionally, my proficiency in mobile app technologies such as Flutter and Ionic Framework (web, Android, and iOS) gives me the edge in delivering a top-notch messaging app that functions flawlessly across platforms. Augmenting this with my understanding of Restful API allows me to effectively integrate additional features like file sharing, voice and video calls, fun engagement elements- emojis and stickers - that would enrich the user's experience.
