The Comprehensive Network Monitoring and Security Dashboard, developed using Java full-stack technologies for Cisco, is a sophisticated system designed to offer real-time insights into network performance, device status, and security threats, empowering network administrators to manage and secure Cisco infrastructures effectively. Throughout the Agile/Scrum-driven Software Development Life Cycle (SDLC), responsibilities encompassed designing use case, class, and sequence diagrams, implementing the front-end with HTML5, CSS3, AJAX, and Bootstrap, and crafting the back-end logic using Core Java, including advanced features like Collection Framework, Multi-Threading, Exception Handling, Generics, and Annotations. Leveraging Full Stack JavaScript (React 14, Redux, and Node.js) and React Context for efficient data management, the application utilized Azure for cloud integration, Micro Service Oriented architecture via Spring Boot, and React-Router for single-page functionality with secure routing. Security was paramount with Spring Security, Docker containerization, and Cassandra for data storage. The project employed Maven for builds, Git for version control, Jenkins for continuous integration, and rigorous testing with TestNG, Jasmine, and Karma. In summary, this project is a holistic solution, seamlessly integrating technologies and methodologies to provide administrators with real-time network insights and robust security for Cisco networks, ultimately ensuring optimal performance and protection.

In my role, I contributed to developing a user-friendly HR management system, including employee data management, payroll processing, and performance tracking. Responsibilities included implementing secure authentication and role-based access controls to protect HR data and integrating databases for efficient data storage and retrieval.Operating within an Agile framework, we consistently delivered new features every two weeks. Leveraging React.js 14, I used Virtual DOM for responsive client-side rendering. Java 9's features ensured interface compatibility and concurrency.The user interface featured pagination components using React 14 Material design for data display across multiple pages. React-Redux managed state, and React-Router enabled seamless navigation, transforming the app into a Single Page Application (SPA).The back-end relied on Spring Boot 2.7 and Spring Cloud services for microservices in the cloud. I troubleshooted escalated issues related to cloud-based identity management and Azure integration.Migration to Dynamo Cloud from the existing data center used Azure Site Recovery and Database Migration Service. Azure API management improved backend operations. Azure Service Fabric cluster deployment and CI/CD pipelines streamlined operations.Database access was managed through MongoDB Data Access Layer with Spring Data's Mongo Repository. Hibernate ensured efficient data retrieval and storage. Apache Tomcat served as the application server, and Jenkins facilitated CI/CD.Git was the version control tool, and I managed branching, merging, and releases. Maven handled project build and documentation.

I worked on this project to create a web-based billing and customer service system. Customers can interact with subsystems such as registration, current policy information, customizing an existing policy, applying for a new policy, making payment, checking the status of claims, and filing a claim, among others. The program generates quotes, displays available plans from the supplier, and walks users through the entire online application process through the web.Responsibilities:Participated in all steps of the SDLC, including specifying, gathering requirements, designing, coding, testing, deploying, and maintaining projects.Angular 6 component-based development improved application performance in light of Angular framework transitions.Applied Java 8 technologies such as Lambda Expressions for array operations, default and static methods in interfaces, and Collections throughout the application to achieve well-defined programming. Spring Boot is being used to create, update, delete, and retrieve information from the backend.Amazon Web Services (AWS) integration with other application infrastructure.Converted a monolithic program to a microservices architecture based on Spring Boot.By building reusable, tested, and efficient code in Node JS and connecting applications to Web Services, I was able to create high-performance back-end applications. Using Angular's component-based architecture, create reusable Typescript components and services that consume REST APIs.Managed the conversion of an existing application to a microservices architecture using REST API, Spring Boot, and AWS. Angular UI Bootstrap components such as calendars, masks, uploaders, sliders, alerts, modal dialogs, and so on were used.Designed, configured, and implemented Amazon Web Services (AWS) for a variety of applications, including EC2, S3, with a focus on high availability, fault tolerance, and auto-scaling.
