Experience
Child-process-es6-promise
https://github.com/nkashyap/child-process-es6-promiseI created the child-process-es6-promise npm package to save repetitive tasks. It is an ES6 Promise wrapper around the Node.js child process API, written in JavaScript, and published on the npm public repository.
Console.IO
https://github.com/nkashyap/console.ioIn 2012, I joined Blinkbox Ltd as a senior software engineer in the smart TV and devices team. It was pretty hard to develop apps for Smart TVs and set up boxes. To overcome the lack of dedicated development tools, I developed Console.IO, an open-source project available on GitHub.
Console.IO is a small Node.js application server with a client library that wraps the "console" object and connects it to the Node.js server. It makes use of Express.io—Express and Socket.IO—to provide a real-time user experience, and the UI gives access to remote web consoles (and more) for web applications. It works on all modern browsers and different platforms like mobile devices, smart TVs, setup boxes, blue-ray and DVD players with Smart Hub, and more.

Giffgaff Mobile App
I built and designed a complete end-to-end mobile platform for product teams consisting of development, building, testing, and deployment processes. Throughout the process, I was able to skill and mentor developers.
Some of the key functionalities of this Vanilla React Native platform using Apollo GraphQL server with AWS and Kubernetes include:
• A shared component library using atomic design principles
• Styled components to build cross-platform components
• A storybook to build components in isolation
• Style components with the theme
• An automated continuous integration and deployment pipeline
• Jenkin to manage CI/CD jobs
• GitHub APIs that are consumed to manage the app release lifecycle
An AppCenter is used for the following services:
• Native and over-the-air (code push) builds
• Endo-to-end Appium tests
• Store distribution
• Google Play Store
• App Store
• Over-the-air (code push) update functionality through the AppCenter
• Feature switch supported via Firebase Remote config
Also, the following Firebase services were used:
• Analytics
• Remote Config
• Crashlytics and Performance through In-App Messaging
• Cloud Messaging

Web Scraping Tool
The tool allowed users to watch for website price changes and send alert notifications when pricing changed. The system had two Chrome extensions, one for the back office and the other for users. The back-office Chrome extensions were used to set tags on the web page to watch and client-side extensions to notify users. The back-end system was built on top of AWS infrastructure and services.
