. Developed applications using MEAN (Mongo-DB + Express.JS + Angular 9 + Node.JS) stack and created POC's for rest service development using Node.JS, Express.JS, and MongoDB. ● Have extensively used Java8 Streams, Lambda Functions, Predicates, Functional Interfaces, Method. ● Implemented Spring Framework including Spring Core/IOC, and Spring AOP for programmatic transaction management, also used other modules of Spring DAO along with Struts Framework to deal with database. . Used Apache Kafka (Message Queues) for reliable, asynchronous exchange of important information between multiple business applications and for building real-time data pipelines. Worked with Git Version control system to track various aspects of the project. ●Worked on Kubernetes to manage containerized applications using its nodes, ConfigMaps, selector services and deployed application containers as Pods. Setup full CI/CD pipelines so that each commit a developer makes will go through the standard process of software lifecycle and gets tested well enough before it can make it to production. ● Developed PL/SQL triggers and master tables for the automatic creation of primary keys. Wrote PL/SQL Procedures for BENEFIT SUMMARY on Oracle 10g database to meet the business requirement of BSD for transactional data for reports. Created PL/SQL stored procedures, functions, and packages for moving the data from the staging area to the data mart. ● Used Maven as a build and dependency management tool for creating EAR, WAR, and JAR files to be deployed in application servers and integrated with Jenkins, and Jenkins Jobs. ● Have written controllers with Groovy to connect front-end interfaces with java services and used them to achieve functionality with reduced code length and developed Groovy test cases. Used AWS deployment services to quickly set up a dynamic website and configured virtual servers using AWS EC2 and was responsible for maintaining and expanding our AWS infrastructure using AWS EC2/EBS.

Developed Web Pages by using CSS3, jQuery, JavaScript, and using JavaScript frameworks such as Angular. Js and bootstrap. Js. ● Established pages using CSS3 to maintain the uniformity of all the screens throughout the application and positioning of screen objects. ● Completed full Software Development Life Cycle from analysis, design, development, implementation, and validation testing using Agile SCRUM methodology. ● Utilized Cloud formation and Puppet by creating DevOps processes for consistent and reliable deployment methodology. ● Used SPRING FRAMEWORK as MVC model Architecture in RMS internet application for direct access to companies. ● Implemented and Supported Production Sales Management Report Application using Spring MVC along with Spring JDBC Template in Apache Tomcat Environment. ● Extensively worked with making calls to REST APIs to fetch the data from the backend as JSON response and parse it on the UI for DOM/CSS Manipulation. ● Worked on Kubernetes to manage containerized applications using its nodes, ConfigMaps, selector services, and deployed application containers as Pods. . Implemented components like Register/Login, Flight-List, Booking, Payment Method, Booking-History, and Feedback using Angular 8, which provides better interactivity and user experience for the customers. . Created REST-ful style Consumer Web Services for Create Bill me, Create Contribution, Get Refund, Join, Renew Account, Update Account, Update Bill Me, Update Gift, Update Person, and Update Person Record using JAX-RS, Jeresy2.11. ● Implemented various Validation Controls for form validation and implemented custom validation controls with JavaScript validation controls. ● Used Bootstrap syntax in the Angular8 platform and point it to the root component of the application instead of Angular ng-app. Non-relational database (Mongo DB) was used to store the data since it provides great flexibility to connect the seemingly unrelated data and expand the schema easily.

● Responsible for gathering and analysis of business requirements. Involved in all SDLC (Software Development Life Cycle) Phases of the project. Tuned Redshift clusters through distribution/sort keys, workload management (WLM), and query optimization, resulting in significantly faster reporting times. ● Assessing project requirements using Agile & Scrum principles related to the high-volume customers-facing portal that helped prioritize developing activities and reduced ad hoc work requests by 27%. Improving product aesthetic and UX of the high-profile internal web application, resulting in 84% increase in sales and product revenue. ● Designing new databases and data schemas for the business-critical online service improving data integrity and execution efficiency applying knowledge of LINQ2SQL. Used React.JS to build the UI components, developed filters to display different dimensions of data and font size modifiers. Developed container components as the logic layer for the UI components. ● Full Stack development of the high-volume customers-facing portal applying knowledge of Redux and GraphQL, resulting in consistent deployment of 10 major products updates. Experience in reviewing python code for running the troubleshooting test-cases and bug issues. ● Designed and implemented MongoDB schemas for storing and managing unstructured data in web applications, ensuring optimal performance and scalability. Leveraged NoSQL databases like Firebase to develop real-time data synchronization features, enabling seamless collaboration and communication among users. ● Implemented efficient indexing strategies in Couchbase to optimize data retrieval and query performance, enhancing overall application responsiveness. Integrated Elasticsearch with front-end applications to enable powerful full-text search capabilities, improving user experience and information retrieval.

● Designing, Developing and Deploying web based multi-tiered interfaces including user account and payment screens using Java, Hibernate and junitg with Extensive use of Java Multi-Threading concepts. Accelerate our adoption of the Kafka ecosystem by creating a framework for leveraging technologies such as Kafka Connect, KStreams/KSQL, Schema Registry, and other streaming-oriented technology. ● Study and analysis of business and functional requirements and Design and development of Software Design Document using UML. Extensive knowledge on spring modules like Spring MVC, Spring Boot, Spring IOC, Spring DAO, Spring AOP, Spring Batch. ● Adhered to Waterfall methodology in the beginning of the project and then transitioned to Agile Methodology with daily status updates and Scrum meetings. Configured WebSphere 7 Application Server to create profiles containing environment and jar library information as well as deploying packaged applications. ● Used Spring Core Annotations for Dependency Injection Spring DI and Spring MVC for REST API, Spring Boot for Microservices and Spring Batch for running batch jobs. Developed entire front end and back-end modules using Python on Django Web Framework. Involved in development using Python, bug fixing and unit testing of the layout commands. ● Responsible for writing J2EE compliant Java code for application development effort which involved working with JDBC, XML, Hibernate, EJB, Spring etc. Involved in SDLC Requirements gathering, Analysis, Design, Development and Testing of application using Agile Methodology (Scrum). ● Played a key role in developing the business layer and data management components of this web-based system over J2EE architecture. Involved in developing web pages using HTML5, CSS3, Angular JS, jQuery, AJAX, JSON, Bootstrap, and Node JS. ● Implemented persistence layer using Hibernate that uses the POJOs to represent the persistence database tuples. These POJOs are serialized Java Classes.
