Hello, I'm Rida Rhnizar.

During my internship at Wadouz Startup, I contributed to two major projects: the Lotentika E-commerce Platform and the Wadouz Mobile App. My responsibilities spanned backend, frontend, and DevOps, with a focus on automation, payment integration, and operational improvements. **Lotentika E-commerce Platform** - Developed and maintained a full-featured e-commerce website and its mobile application. - Implemented a CI/CD pipeline for automated deployment on AWS. - Fixed payment issues with NAPS and improved the mailing service. - Added Cash on Delivery (COD) payment options for both the main site and the back office. - Integrated Aramex API for automated shipment creation. **Wadouz Mobile App** - Integrated the Meta WhatsApp API for OTP delivery and messaging, overcoming significant challenges due to Meta's strict approval process and complex API requirements. - Navigated Meta's business verification, phone number approval, and template message review processes to successfully obtain and activate the WhatsApp Business API. - Enhanced user communication and authentication features. - Collaborated with the team to ensure secure and reliable messaging. - Assisted in testing and deploying new messaging functionalities.
