PROFESSIONAL EXPERIENCE:

Confidential, Reston, VA

Full Stack Java Developer

Responsibilities:

Confidential, Rockville, MD

Full Stack Java Developer

Responsibilities:

• Modularizing big chunk of sophisticated program sections and gluing them back with Enterprise JMS brokers like ActiveMQ.
• Bug fix by implementing proven programming practices like robust exception handling, configurable approach for properties (the application uses JMX very extensively, & Spring Cloud Config), Rigorous and regular refactoring, integration of proven design patterns.
• Web service testing and mock service preparation using tools like SoapUI.
• Modernization and optimization:
• As part of this modernization, I've implemented a standalone Apache Camel powered Amazon SQS consumer API and separate Spring Boot web service as a test client. The Apache Camel router is dynamic and extensible which can add more producer/consumer routs to the running Camel context at runtime and give back the consumed messages to the client’s custom processing bean.
• This is one of the efforts to move/migrate some of the existing GMM functionalities to AWS cloud - Amazon SQS, S3, DynamoDB, Lambda, Elastic Beanstalk and more.
• SurveyMonkey integration: Used SurveyMonkey to gather user experience on our system so that we can easily analyze the result and work accordingly to improve the pages and features with low ratings.
• Securing RESTful web services: With our recent componentization of big modules in to manageable micro services, the need for authorization and establishing trust between the services was essential. Implemented stateless spring security using JWT to establish the trust between our client/server and micro services. Added a JWT enabled Java REST client with secured keystore and self-signed certificate management capability.
