Javascript was extensively required as I was mostly writing web applications for the past 6 years now. Used it mostly for UI coding. Love the functional aspects of javascript (callbacks and promises). Our recent library has a javascript file with more than 1000 lines of pure javascript (no jQuery).

Built web applications for more than 6 years now. Know to write responsive CSS and have worked extensively with the Bootstrap framework. https://www.juspay.in uses Bootstrap.

Learned android about two years ago. In Juspay, we have built a very specialized paysments related Android SDK to help customers deal with payment authentication. Specifically, the SDK has been optimized for performance. The library cannot also crash as our clients demand that high quality from us. It took a lot to achieve that and we have achieved that. Our demo app for the library is available here: https://bitbucket.com/juspay/rr-android.git.

However, Android is very big and I am not particularly aware of all the UI components that it offers. So, I can't help out much on that front.

I have used Grails for several projects in the past 5 years and Juspay runs in Grails. 

Groovy is a dynamic language which is the primary programming language for Grails projects. I have used this language both in the framework scope and scripting scope. 

All the projects in our startup is hosted on a git server. I personally manage the accounts and repositories. Have performed thousands of commits/merges over the course of past 5 years. 

I manage about 20+ ec2 instances, 4+ rds instances running mysql all inside a private VPC with rock solid security (PCI compliant stack).

Mysql was the primary choice for database for all my projects. Have used it extensively since 5.0. I am adept at tuning InnoDB for performance. Have setup MyISAM engine for data warehousing at my previous company. In my previous company, our team setup master-master replication with immediate failover and we had tuned the system for amazing performance to offer more than 900 TPS.

When I started using jQuery, the stable version was 1.2.1. Since IE6 had big share in those years, jQuery was how we would deal with javascript code of the browser. I would have written thousands of lines of code mostly using jQuery in all my projects combined. 

Started coding in Java right from college days. It is the primary language for all projects that require performance. Presently, I am working on a data layer which uses multiple data sources (Google BigQuery, AWS Redshift, Mysql) to fetch data for our analytics system and show it in a neat dashboard.
