• Develop software using object-oriented languages such as Scala and Java, perform some scripting with Python and Bash. Implement system measurement and monitoring capabilities (Prometheus, Grafana, xMatters).

• Experience using Map Reduce in Hadoop batch jobs and Spark streaming services to process large scale data.
