PROFESSIONAL EXPERIENCE

Confidential

Java Developer

Responsibilities:

• Developed few applications like IPSearch, Bulletin Manager and DMCA.
• Developed application using Spring Boot, Cloud Foundry, Rabbit MQ, Jedis Cache, Rest Webservices and MYSQL.
• Built on Cloud Foundry - PaaS allows more engineering focus on building business functionality and less focus on server & infrastructure maintenance.
• Built on Spring Boot - Spring Boot is the industry AND Confidential standard Java framework. It enables faster development & greater reliability than the previous platforms like JBoss & Weblogic. It provides deployment flexibility in that it can be run on CF, container, or bare VM.
• Built on Spring 5.1 - Designed and developed IPSearch application with spring 5.1 and spring JDBC.
• Easy Instance / App Scaling - There is no longer a need to manually request new VMs when new scale is needed, a few clicks of the mouse will give you new instances for additional performance and redundancy.
