Project: CSW (Cisco software workspace)

Description: The project involved the development of an internal application specifically designed for Cisco support engineers. The primary purpose of the application was to manage various aspects related to user roles, access control, and licenses for products such as routers, switches, and access points. The application provided a comprehensive system for managing user roles within the organization. Support engineers could define different roles and assign appropriate permissions and privileges to each role. This allowed for fine-grained control over the access and actions that users could perform within the application.

RESPONSIBILITIES:

The CSW application is a Single Page Application (SPA) developed using Backbone.js and Marionette.js. It incorporates various features and techniques to enhance the user experience and improve performance. Here are the key points about the project:

Backbone and Marionette.js: The application utilizes the Backbone.js framework along with Marionette.js, a framework built on top of Backbone.js. Marionette.js provides additional abstractions and features to simplify the development of complex applications.

Reusable Views and Collection Views: Marionette.js is used to create reusable View templates and Collection Views that can be rendered multiple times in the DOM. This promotes code reusability and simplifies the management of complex UI components.

Slickgrid Application: The application integrates the Slickgrid library, which is used to efficiently display large amounts of data records with a single service call. Slickgrid enables smooth scrolling and handling of millions of data records.

Routing and Template Caching: Marionette.js is used to configure routes and create regions for managing different sections of the application. Template caching is employed to optimize rendering performance and improve overall application speed.

Custom Events: Custom events are written in Backbone.js to trigger specific actions and interactions on Models, Collections, and Views. This allows for efficient synchronization and management of data.

Integration with RESTful Services: Models and Collections are developed to interact with RESTful services, performing operations such as retrieving data (GET), creating new data (POST), and deleting data (DELETE) from the backend. This ensures seamless integration with the server-side APIs.

Agile Methodology: The development process follows the Agile methodology, with a focus on delivering user stories within tight schedules. This requires efficient time management and adherence to Agile principles and practices.

Performance Optimization: Efforts are made to improve the performance of the application. Performance tools in developer tools, such as Dev Tools and YSLOW, are utilized to analyze and optimize the page loading speed, rendering performance, and overall user experience.

POC with ReactJS and Redux: A Proof of Concept (POC) is developed to create an ajax-driven tabular component using ReactJS and Redux. This demonstrates the potential of using these technologies for future enhancements or migration.

By leveraging the capabilities of Backbone.js and Marionette.js, implementing efficient data handling, and optimizing performance, the CSW application aims to provide a robust and responsive user interface for managing data records and meeting the requirements of the project.

PNP (Plug and Play)

Description: This internal application is designed to support engineers' team in managing device assignments to controllers. The application consists of two modules: Devices and Controllers. In the Devices module, users can upload information about various devices such as switches, routers, and access points. The device details typically include the serial number and MAC address. Upon uploading, the application automatically assigns the device to an available and compatible controller. The Controllers module is responsible for managing the controllers in the system. It keeps track of their availability and compatibility with different types of devices. The application ensures that each device is assigned to an appropriate controller based on its characteristics and compatibility requirements.

RESPONSIBILITIES:

Developed the PNP (Plug and play) Single Page Application using Angular.js, leveraging its powerful features for efficient front-end development.

Created custom Angular directives to manipulate data and display it in the company's standard format using the Slickgrid application library on the UI.

Followed the core MVC structure to develop the application, utilizing factories and services for seamless data communication between controllers.

Utilized various AngularJS directives such as ng-router, ng-table, angular translate, angular file upload, and ng-repeat to enhance the functionality of the application.

Designed user interactive (UI) web pages using HTML5, Twitter Bootstrap, and XHTML, ensuring a visually appealing and user-friendly interface.

Collaborated closely with the business team during user story grooming, providing valuable input on requirements and functionality.

Participated in design discussions and user experience sessions to contribute to the layout and overall user experience of the application.

Implemented Grunt.js for code minification and compilation, streamlining the build process with the help of Node.js.

Improved code quality through continuous integration (Jenkins) for static code analysis and regular code review sessions with peers.

Attended daily scrum meetings, providing updates on tasks, discussing any difficulties, and seeking clarification when needed.

Simultaneously wrote Selenium test cases with Java and Jasmine while developing user stories, ensuring comprehensive test coverage.

Efficiently addressed and resolved bugs reported by the QA team after the release of user stories.

Used Rally tool to track and update effort spent on various activities such as user story development, bug fixing, story grooming, and training.

Deployed the code on different environments (Dev, Stage, Production) using Jenkins and FileZilla, ensuring smooth deployment process.

Conducted demos to the end client after the acceptance of user stories by the QA and business teams, showcasing the application's features and functionality.
