- Architected high-performance RESTful APIs in .NET to replace regex-based validation logic, enabling real-time software diffing and improving response times by 500ms
Frontend Intern
- Implemented item, buyer and seller coupons on the Mercari website affecting over 5 million transactions in one month
- Buyer and seller coupons allow buyers to see and sellers to add coupons on items
- Item coupons add coupons on difficult to sell items thus allowing them to be sold quickly
- Refactored existing code to optimise item rendering and implemented DRY policy to implement coupons thus keeping the codebase minimally affected
- Implemented on the fly switchable PR environments and API PR endpoints allowing for a smoother development experience
- Worked extensively using NextJS and Context API
Front-End Developer
- Worked as a Frontend Developer, at AI4Bharat, IIT Madras
- AI4Bhārat is a non-profit, open-source community of engineers, domain experts, policy makers, and academicians collaborating to build AI solutions to solve India’s problems
- Refactored an existing project (Subplayer.js), to support various new features like direct translation from English typing to Hindi, and a new feature to support multiple vernacular languages
- Built using React, Redux, and Ant Design
- Worked on an in-house project Shoonya, that has functionalities to undertake a project, for collecting or annotating data
- Created a workflow to create Annotation Projects with dynamic forms wherein progressive inputs change according to the previous selections
- Worked on displaying the Projects page, and add new members to the project as well
- Used extensively for captioning purposes in NPTEL videos, which is the largest provider of MOOC courses in India
- Checkout my work here
Front-End Developer and Maintainer
- Worked as a Frontend Stack Developer, at Spinup, Horizon Technologies
- Spinup is an Open Source AWS RDS alternative
- Users can register on GitHub, select a type of database, and use it according to their needs
- Built using React, Redux, and Ant Design
- Used Axios for API Calls to create, delete and update databases
- A Profile page for customising each cluster is also implemented
Full Stack Developer
- Worked as a Full Stack Developer, at FOSSEE, IIT Bombay
- Developed a Version Control System, for users to save multiple versions of a circuit, and to revert back to previous versions, giving users the freedom to explore various options without the fear of losing progress
- Branching is also supported and the user can create multiple branches according to his needs
- Integrated versioning with workflow to publish various circuits, with the ability to publish various versions of the circuit
- Worked on adding a Popup bar for setting component properties, which allows users to set the parameters of a component right next it.
- This is especially useful as it allows direct integration of the Schematic Editor in various places without the need to add the entire page.

MVP & POC Intern
- Worked at iMocha as a Full Stack Development intern
- Worked on extending the current functionality of the skill assessment platform of iMocha
- Used a browser based IDE, Eclipse Theia, to create a development skill assessment POC project
- Users can login, with a particular test link, the details of the test, which are set by the admin are then loaded in.
- A Docker container is created for the user to attempt his assessment in. A folder structure is displayed, the user can create as many files and folders as he needs.
- Buttons for running and stopping the service without touching the terminal is also implemented, although the user can use the terminal is he wants to
- On submission, the server will zip the submission, and push it to a persistent storage like Amazon S3 or Microsoft Azure. The admin who created the test can then view submissions and download them according to his liking
- The Theia workspace comes with a browser preview extension built into it, the user can run the project on any port he likes and view the project freely
Backend Developer
- Developed the backend of the PrepiiT Quizzing Platform
- Developed a RESTful API in NodeJS, and the framework used was ExpressJS
- Used PostgreSQL as Database of choice
- Everytime a user wants to give a test, questions are randomly picked from the Database according to the paper pattern set by the admin
- Admin can add, remove, edit all questions and tests, bulk questions can be uploaded in CSV format
- All users get their test analysis which is all handled in the backend
- Live Testing feature is also available (Test will be available only for certain amount of time)
Projects
Remote Code Executor
A Remote Code Executor powered by NodeJS and Docker, a new container is built for every new code submitted on the server, SocketIO is also integrated in this project for a real-time collaborative coding session. Appropriate Toast Notifications are also shown for every user joining and leaving the room
Deployed on AWS on an EC2 instance, used Cloudflare as a DNS provider for HTTPS support, implemented SwaggerUI for API exploration
ReactJS NodeJS ExpressJS Docker
Discord CodeBot
As proof of concept of extending the existing functionality of the Remote Code Executor, I decided to make a Discord bot powered by DiscordJS and NodeJS. This bot reads messages sent by the user and on encountering a message starting with !code it reads the rest of the message as commands, by splitting the message, I extract the code, and the language of execution and I send it to the main server which returns the output. The bot then tags the user who requested the output and prints the output/error
DiscordJS NodeJS
CodeFiddle
A complete Visual Studio code experience in the browser, built with Docker, Node, React and Websockets. No expensive libraries, no Socket.IO. Handled everything from initiating connections to upgrading them
The user is also given a terminal, which directly interacts with a dedicated docker container spun up for the user. Recursively hydrated folder tree so that items can be created and accessed at any arbitrary depth
ReactJS Websockets Docker NodeJS
Real Time Chatting App
A real-time chatting application built in the MERN Stack along with SocketIO for real-time functionality. Similar to WhatsApp, the app allows users to send messages to each other and also create rooms, and add other users to the room. Users being added to the room have their group list updated in real-time using the same socket events. New messages in a group causes the group color to be updated to green for users not in it currently.
Deployed on Netlify, Heroku using Mongo Atlas as a Database
ReactJS NodeJS ExpressJS MongoDB SocketIO
Discord MusicBot
After the shutdown of major music player bots like Groovy on Discord, I created this Discord bot as a replacement to other popular bots. You can request a song play using the !play command, and you can also request lyrics of the current playing song. I have used Cheerio as a web scraper to fetch lyrics from the first match on a Google search.
As an added easter egg, private messaging the bot causes it to act like a chat bot, have fun asking the bot questions and receiving weirdly diplomatic answers!
