FR Search engine

Developed a search engine built on top of 10 million+ users documents store using Java, Spring boot, ElasticSearch and Hibernate.

• Utilized Elastic Search capabilities to build a highly efficient search engine.
  
• Infra design and sharding strategy.
  
• Schema design, Mapping definition creation,
  
• Metrics, Bucket & Nested Aggregation creation with Java.
  
• Query creation with Java API.
  
• Displaying aggregation results based on search criteria.

FR data Migration Service:

• Developed a Migration service built using Spring batch, which migrates data from Postgres to Elasticsearch.
  
• Utilized readers, writer and processor to process data.
  
• Fault tolerance mechanism for failed records.
  
• Migrated around 10 Million records from different postgres db to secondary data source.,.
  

FR Push Notification system:

Built an event driven microservice architecture to achieve a push notification solution.

• Notification Service: Built a highly efficient push notification system right from scratch, which processes, creates and triggers more than a million notification messages per day. Used AWS SNS as notification service. Utilized Rabbit MQ for asynchronous processing.
  
• Job Scheduler Service: Built a Job Scheduler Service from scratch, that triggers events based on configured time using the Quartz scheduler. This event triggers complex business logic and performs operations.
  
• User Service: Service used to fetch user specific data and process accordingly.
  

FR Job Scheduler service:

• Developed a job framework which takes care of timely execution of events and jobs.
  
• Utilized quartz scheduler API.
  
• Configured Job using cron expression.
  
• Accommodated run time updates without server start.

FR Event Service:

• Event Service: Designed and developed an event service which keeps our users informed of events happening in and around. All the event are store in database tables, entries to these tables comes typically through a CMS admin console. People can actually mark their interest for going not going to an event.

FR News Service:

• News Service: Built a Micro-service which would source latest News to our users. Similar to thee event system.
  

FR Referral Service:

• Referral Service: Developed and delivered a referral system, which enables users to refer the app to their contacts and earn rewards and benefits.
  

• Practiced test-driven development and pair-programming for quality code using JUnit and Mockito . 
  
• Continuous code quality monitoring and review using Sonar and language experience. Used GIT for versioning and Jenkins for deployment.
  
• Spearhead development of an asynchronous architecture using RabbitMQ.
  

• Worked with third party APIs such as Wunderground & Google maps locations API.

• Worked closely with clients, in order to understand the need & scenarios for development.
  
• Involved in code reviews and implementing best practices for coding and design.
• Helped team in optimizing and developing different user on-boarding scenarios for a seamless user experience.

• Worked on migrating millions of records from Cassandra to Elastic Search.
  
• Used Spring batch for batch processing and used Cassandra as primary database.
• Built a search functionality using Elastic Search and AngualrJs.
• Elastic Search Schema design, Mapping definition creation,Metrics, Bucket & Nested Aggregation creation with Java. Query creation with Java API. Displaying aggregation results based on search criteria on UI using AngularJs.

• Built web front-end using HTML, JavaScript and CSS.

• Used JSTL in JSP for page rendering.

• User legacy Spring framework for ease in development.

• Worked extensively on Ajax and other similar front-end technologies.
