Hello Sir,
I am Peter Voivontas, a web developer from Greece. I have 6 years of experience working with JavaScript and its various frameworks and libraries such as ExpressJs, and ReactJs. Most of my experience comes from building APIs and web experiences for user authentication. As far as technologies go, I have experience using Google Firebase for user authentication. Furthermore, I am proficient in MongoDB, my NoSQL database of choice, which will be useful should you want to save your data to a server.
Lastly I should point out that I am trying to provide a client with value first by trying to bid as low as possible. After all I am new to Freelancer.com
I look forward to working with you.
Peter Voivontas
