Creating scalable backend solutions for many applications. I've used it for API's, crawlers, workers, realtime features and different tools. It is also used as the core language in my open source search backend https://github.com/itemsapi/itemsapi

Experience working with many startups from USA, Germany and Poland and also experimenting with my own projects. Validating ideas, creating MVP, choosing most productive technological stack

I've used it for great searching, filtering and as recommendation engine for many projects. I am using it also as the core technology in my open source project https://github.com/itemsapi/itemsapi

I've used it as very scalable mechanism for caching, session storing and also for the work queue systems

Used it everywhere when needed to prototype and validate ideas fast and where transactions are not critical

Experience with ec2, S3, elasticsearch, route53, load balancer

I've used MySQL from the beginning of my career in many projects especially those requiring transactions i.e. ecommerce or auction systems. Personally I prefer NoSQL as it allows to prototype applications and create MVP faster.
