Work Experience
Senior Software Engineer | Full-stack Developer
2020 - PRESENT
ValueLabs
- Developed modular, scalable, and maintainable components using React. Incorporated state management using Redux, Context API, and Zustand; and API management with React Query for large-scale web applications.
- Contributed to developing a React application to automate the deployment of our applications to development, test, and production environments with a single click of a button.
- Created a user management module using React that features sign-up, reset the password, and forgot the password screens, including sending email notifications to users for sign-up and forgotten password requests.
- Tested extensively React applications using React Testing Library, Jest, and Enzyme. Wrote unit, integration, and end-to-end tests to ensure the quality and reliability of applications.
- Used TypeScript to build robust and scalable applications, leveraging its strong typing and object-oriented features.
- Developed a Node.js REST API project to process incoming data sent by other applications and services and then store it in a database to further create files with the processed data on a scheduled basis using Cron jobs.
- Implemented OAuth 2.0 in an ASP.NET core project using the IdentityServer4 library, providing centralized authentication for all our applications to securely communicate with other protected resources by exchanging access tokens.
- Collaborated with the systems team to write Jenkins scripts for multi-branch and declarative pipelines, which allowed applications to automatically deploy to our Kubernetes cluster when the code was pushed to a Git branch or a tag was created.
- Involved in creating and maintaining Docker images for applications, ensuring consistent and reproducible builds across different environments.

Experience
English Dictionary
https://shankar369-dictionary.netlify.app/I developed a single-page application using React that allows users to search for the meaning of a word. The application retrieves data from Google's dictionary API and displays it on the UI. It also provides the ability to listen to the pronunciation of a word through the UI.
Restaurant Rating App
https://rate-restaurant.netlify.app/This application is a web platform that allows users to discover and rate restaurants. With React for the front end, Node.js for the server, and MongoDB for data storage, it offers user registration and login. Users can browse restaurants, search by criteria, and submit ratings and reviews. Admins have additional privileges to manage restaurant listings and moderate user-generated content.
GitHub Finder
https://shankar369.github.io/GitHubFinder/I developed a dynamic single-page web application using GitHub's API to search user profiles by their GitHub user ID. The application fetches the user's details from the API in real time without reloading the page. This enables a seamless and user-friendly experience for finding and browsing GitHub profiles.
Mini JavaScript Apps
https://mini-js-apps.netlify.app/I created mini-apps using JavaScript to gain practical knowledge of concepts essential for building real-world applications. Making these smaller applications gave me hands-on experience with JavaScript fundamentals, such as working with DOM manipulation, handling events, implementing asynchronous operations, and managing data. This approach solidified my understanding of JavaScript and provided a foundation for tackling more complex projects. Through these mini-apps, I honed my skills in problem-solving, debugging, and implementing best practices. This practical experience was invaluable in preparing me to develop robust and efficient applications in the real world.
2048 Puzzle Game
https://shankar369.github.io/2048-puzzle/2048 is a popular sliding block puzzle game that was developed using JavaScript. The game's objective is to slide numbered tiles on a 4x4 grid to combine them and create a tile with the number 2048. I developed the game with HTML and CSS. I also implemented game logic and UI elements using vanilla JavaScript.
