Dear client,
I'd like to apply your job because I think that I'm suitable freelancer for your job.
I have development experiences as following.
PHP: I have experiences in this area for 5+ years.
Node.js : for 2 years. Now I used to develop back-end web service with node.js for my mobile app.
In addition, I have experiences in AWS such as Lambda, DynamoDB, S3 bucket, StormPath, EC2, etc.
As an example, I developed mobile app(which named VanPool, enterprise not publish) using Lambda+Node.JS ,DynamoDB, Stormpath(for user profile management) on iOS&Android platform.
I'm not familiar with Fluentd and Redis you outlined, but I can overcome every difficulty in new technology.
If you interested in my proposal, I would review the all requirements of the project in more detail.
Looking forward.
