• Created a Spring based application (Library), which will be used all the teams in the organization to communicate and interact with Platform owned services• This library will provide a uniform way of doing connection management, exception handling, error message logging, sending, and receiving of JMS messages between different applications• The application team would only need to focus on writing the business logic and not worry about configuration management part of the working with any JMS Compliant MOMs• Write unit tests using Junit and Mockito to improve code coverage and integration tests using docker environment.• Used Jenkins for Continuous Integration and Continuous Deployment.• Development and support of Restful Web services that support JSON using Spring Web services (JAX-RS), JSON & Spring MVC Module.• Performed build, deployment & validation of the code into different development environments (DEV, SIT, UAT). • Worked with Devops team to create a complete CI/CD pipeline for one of the internal applications which is responsible for generating release information throughout the organization• Updated few services to use the library by injecting the dependency and using the library provided beans to connect, send and receive messages• Working on upgrading Spring & Spring boot versions of legacy applications to address application security vulnerabilities and resolve them in timely manner• Developed an application based on J2EE (Java 8) using Hibernate, Spring, and SOAP/REST web services.• Used Eclipse IDE for application development. Used Jenkins Jobs for build automation to compile and generate EAR and WAR files• Implemented business layer using core Java, Spring MVC using dependency injection, and Spring annotations.• Integrated Spring with Hibernate using configurations and implemented DAO layer to save entities into data base

• Developed multiple scalable and efficient Spring and Spring boot-based SOAP and REST backend services to address product requirements• Developed with Spring boot standalone applications to interact with Kafka cluster hosted in a different network and created listeners which were constantly consuming messages• Developed webservices SOAP, WSDL and webservices clients using JAXB and XML, implemented SOA architecture• Developed interfaces and their implementation classes to communicate with the mid- tier (services) using Middleware like JMS• Implemented DAO layer using Spring JDBC Module to call DB2 stored procedures from the application• Used Spring Core Annotations for Dependency Injection Spring DI and Spring MVC for REST API s and Spring Boot for micro-service• Implemented SPRING MVC application framework to create and configure of Java beans using SPRING IOC and used SPRING Hibernate support, transaction management• Setup Alerting and monitoring using AWS.Involved in migration activities of Java scripts and Database scripts from Oracle, MS SQL Server and MYSQL into different environments• Developed end to end data processing pipelines that begin with receiving data using distributed messaging systems Kafka for persisting data into Cassandra• Worked with Agile Methodology (SDLC), involved in daily scrum meetings, sprint planning, product backlogs•Worked with GIT version controlling system for continuous developments using agile methodologies• Supported existing Legacy application called Datagrid which is a combination of Couchabase + ES + Java application• Involved in fixing application bugs and testing on a day-to-day basics and responsible for pushing code to production environment• Designed and developed of web-based application using Java 1.7, Spring, and SQL. Development and support of Restful Web services that support JSON using Spring Web services (JAX-RS), JSON & Spring MVC Module

• Provide Support to existing services by developing complex TSQL Scripts and rewriting the Old legacy Code in a better way • Created different Reports Using SSRS which would be used by the OPS team for getting alerts, monitoring systems and Capacity planning purposes• Looking into new reporting framework like (Qlik), to make sure how this can be introduced into the current environment and can be used to replace SSRS(Static reporting Framework)• Developed reports Like Chi square test and Index/Merge Throughput reports which were used for internal purposes to determine the effect of code and hardware on the current system.

• Maintaining the current Dictionary infrastructure which is consumed by the clients to know statistics pertaining to their websites and its users• Using Synaptica (Third Party tool) to create and maintain new Dictionaries (user agent like OS/Browser and Device). Single point of contact for Synaptica(third party tool) which was introduced in the organization, hence proving the willingness to take responsibility and being accountable for it and delivering solutions as promised in a timely manner.• Developing Perl scripts for automating the loads and updates and integrating and automating them using SSIS Packages(Calling the batch files)• Writing Complex TSQL Scripts (Stored procedures, views,UDF’s and triggers etc) to complete the stories assigned in JIRA as a part of the Monthly sprint tasks.• Identifying slow running queries using profilers or directly from the Client Service team and working on resolving these queries by studying the executions plans and performing various other checks depending on the way the query is written.• Coming up with SSIS packages to automate many different production related processes, which required manual effort earlier.

• Actively Involved in Data Modelling, which included creation of Logical and Physical data models using ERWIN, also used different ERWIN functionalities to come up with scripts and data models to meet the Organizations standards• Responsible for performing SDLC for different modules, which requires script maintenance and execution as and when required on different environments like Test, QA, OS and PROD • Actively involved in understanding business needs by collaborating with developers and was responsible for developing efficient queries and migration scripts.• Developed complex database objects like stored procedures, views, functions, triggers, SQL jobs and performed query tuning. Also used advanced concepts like CTE’s, Pivot, Ranking functions and advanced XML functions like nodes, value, modify etc.• responsible for performing Database refresh on different environments as requested by different Solution teams• Created database users, logins and roles at the database and server level, with appropriate permissions and access control mechanisms• Monitored Database alerts, failures and blockings on production Environment and took appropriate actions to fix the problems • Came up with SSIS Package to refresh internal environments from production database backup with ROBOCOPY command• Worked closely with Production Support team to investigate and resolve some of the production issues, also documented these issues on the company WIKI page so that the solutions can be used as a reference in the future.
