Hello Connou.
According to your job post, I have clear understanding about your requirements such as verify emails and I am very confident for your project because I have similar work in the past - I have experienced SMS verification for phone number in PHP and Laravel framework.
I am expert in Typesript, Google Firebase, React, Node, Angular and I can finish your project in very short time.
I would like to discuss with you in details.
Thank you for your kind attention.
