Dear Sir,
I found this project quite interesting and I understand it will require to use OAuth with access token to be able to answer to the reviews.
I am guessing you want to use one account for all of your users in the portal so that every user can answer to the reviews as main account.
I have done several projects using Bootstrap, PHP, MySql, WordPress, OOP, HTML CSS Javascript JQuery and AJAX successfully.
I have done Google API integrations multiple times including Microsoft Graph APIs, Office365, Google Analytics, Google Calendar, Gmail and Youtube.
I am an Electrical Engineer and have earned Master's Degree in Information Security.
I have been a professional developer for several years and very familiar with web programming.
I'll try to do this job as soon as possible. I'll be glad to work with you.
You can see some of my own work in my profile, which provides additional information on my background and qualifications.
I look forward to hearing from you soon.
Thank you for taking the time to read my application.
Best Regards,
M Shahbaz
