Java is the first language I ever learned and I still use it regularly. I'm extremely comfortable with all the associated tools like Maven / Jenkins / IntelliJ, etc.
I'm no DBA, but I've written and tuned a lot of SQL code over the years, including MS SQL server, MySQL, Hive, Phoenix, and Spark
I'm comfortable across the stack, including tuning Tomcat, deploying .WAR files, writing scalable, performant Java APIs, and most recently - working with AWS Elastic Beanstalk (scalable web server as a service) and API Gateway (REST API as a service)
I helped build our corporate data lake from scratch on a Hortonworks Hadoop cluster that I primarily maintained. I'm comfortable with Hive, Tez, Map Reduce, Spark, Ambari, HBase, Phoenix, etc.
I spent a large portion of the past year working in EMR, including Hive, Tez, and Spark queries, and writing Java code against the API for dynamic creation and use of clusters.
