I am Alireza Chehreh, a Python developer with 3 years of experience in Django, Flask, HTML, PostgreSQL, MongoDB, and AWS. I would like to offer my services to develop a solution for your project to display audio and video after reading a QR code. I can develop the solution using Python and host it on AWS. I am also skilled in software architecture and can provide administration features like batch uploading of text and video, user traceability, QR code generation, and audio translation using Amazon Polly.
My question for you is, have you considered using any particular libraries or frameworks to achieve this project? I look forward to hearing from you soon.
