Improvement / further development of the module working with the WhatsApp API (official) is required
Brief summary: A web module was written that works with the Whatsapp API, based on the documentation. All code is written in Yii2. Further refinement of existing methods and development of new functionality is required. Details in personal communication.
Ideally, I am looking for a full-stack developer who speaks Russian, senior level (Yii2) for long-term cooperation.
