Lead Engineer

Responsibilities:

• Project Description: As part of project, we are building a New Credit Acquisition system leveraging cloud technology and set of micro services that produces, consumes and/or stream messages from KAFKA clusters, real time data analysis & gather insights from Data Analytics. I worked on various microservices like Identifying duplicated applications, Fraud identification and management, customer 360 info etc.
• Transformed legacy application into a suite of cloud hosted Microservices using Spring Boot and laid the groundwork to handle x10 of current traffic scale.
• Designed and developed asynchronous RESTful Microservices using Java, Java EE, XML, JavaScriptJSP, EJB, JDBC, Servlets, JMS, Java API for XML Web Services, Spring, Hibernate, Spring bootPivotal Cloud Foundry and Kafka.
• Involved in the development of project back - end logic layer by using most of the core java features such as Collection Framework, Interfaces, Multi-Threading and Exception Handling programming.
• Applied jQuery, Bootstrap, CSS3, JSP, and JSTL to build interactive and dynamic UI.
• Used AJAX calls for data updates in UI along with JSON data parsing
• Worked on infrastructure with Docker containerization.
• Kubernetes is being used to orchestrate the deployment, scaling and management f Docker Containers.
• Developed the Application using Spring Features like Spring MVC, ORM, Spring Boot and Spring
• Security for application access and authorization, Spring Integration, Spring AOP for crosscutting concerns.
• Created computing and data resources on AWS using EC2. Installed Pivotal Cloud Foundry on EC2 to manage the containers created by PCF.
• Designed Spring boot mechanism without configuration XML's and replaced it with Java classes and also used Spring boot Actuator to externalize application's configuration properties for different environments.
• Developed various screens for the front end using React JS and used various predefined components from NPM and Redux library
• Involved in writing SQL queries for retrieving data from MySQL, HBase and GEMFIRE.
• Used Micro service architecture, with Spring Boot based services interacting through a combination f REST and Apache Kafka message brokers. Produced and consumed centralized Spring Restful Web
• Services for Enterprise and web applications to consume in JSON format and in trusted client-server environment.
• Used Jenkins pipelines to drive all micro services builds out to the Docker registry and then deployed to Kubernetes, Created Pods and managed using Kubernetes
• Refactoring of monolithic applications to a Microservices and Component based architectures.
• Configure build pipelines to support automated testing and deployments using tools including
• Jenkins, PCF Code Deploy. Configure these pipelines for specific products and help optimize them for performance and scalability.
• Worked on Git as version control management and JIRA as Defect management for bug, issue tracking of application and gained good experience by working with configuration management tool Ansible, CI/CD tool Jenkins and ISO 8583 message patterns.
• Used Apache Camel to transform incoming JSON from 3rd parties.
• Participated in the technical code reviews, prepared unit test cases, detailed time estimation and impact analysis and code review documents.
