Hello Sir,
I have demo to show you my previous work for rest APIs. Let me know if you want to check them.
I am an experienced web developer with more than 6 yrs of experience in Php, Nodejs, MySQL, nosql, JavaScript, jquery and other related technologies.
I do believe that I am the right candidate for this job because I have hands on experience in the technologies you need and also have excellent debugging skills.
Let me know if you have any query.
