Working on projects with Waterfall and Agile methodologies such as Test-Driven Development (TDD) , BDD, and SCRUM.Used Apache Kafka for handling log messages that are handled by multiple systems. Working with Front-end JavaScript frameworks like Angular 7, Nodejs. And with the creation of RESTful Web service.Involved in the design & development of SQL queries, MySQL, Multithreading, Restful Web, Functions, and Stored procedures for performing database operations. Work on Hadoop Ecosystem (Pig, Hive, Impala and Spark, Scala), Java, and J2EE.Developed Spark Applications by using Scala, Java and Implemented Apache Spark data processing project to handle data from various RDBMS and Streaming sources.Developed and maintained features in the Java backend of applications using continuous integration testing boxes under the Linux command line. Deployed build to SIT (System Integration Testing) Server using a customized JBoss menu in Linux and Unix.Application deployment and debugging is performed in a Linux environment and used Putty/ WinSCP to access the Server Logs and worked on the code debugging using memes cape debugging tool. Optimized Microservices using Nodejs and ES6 as interfaces to Cassandra NoSQL database.

Managed large datasets using Pandas API ecosystem to analyze the different segments of customers based on Location. Designedand developed Common Frameworks within the organization using Spring Batch, Apache Kafka and Bean IO Frameworks.Involved in coding with Core Java concepts like Collections, Exception Handling, Multithreading, Java I/O, and Generics toimplement some business logic.Worked on creating the Docker containers and Docker consoles for managing the application life cycle. Setup Docker on Linuxand configure Jenkins to run under Docker host.Developed algorithms to analyze gene expression data using Bayesian statistical techniques and ran the algorithm on Linuxdebugging server and Implemented code porting from Solaris system to Linux system.Created common reusable objects for the ETL team and overlook coding standards and reviewed high-level design specification,ETL coding and mapping standards and Developed native Scala/Java library using Jsch to remotely execute Auto Logs PerlScripts.Designed and developed asynchronous RESTful Microservices using Spring boot, Couch base and RXJava that are consumed byother microservices with an average response time of 30 milliseconds.Involved in writing SQL Queries, Stored Procedures. Involved in Unit testing using JUNIT with Mockito and integration testing.Implemented Spark using Scala and Spark SQL for faster testing and processing of data and implemented Spark using Scala andutilizing Data frames and Spark SQL API for faster processing of data.
