Employment

  • Senior Software Developer

    2018 - 2021

    • Worked alongside product managers and UI/UX designers to develop a full-stack web application that took over the network of buyers and sellers of 10,000 users, with buyers and sellers being onboarded daily.
    • Pioneered organizational initiatives, including a developer swap and mentorship program as well as squad sharing initiatives. Improved employee onboarding across a tribe of 40 members by creating documentation to enhance the whole onboarding process.

    • Designed and implemented an optimized solution for order transmission, replacing the existing one and drastically reducing the amount of maximum time it takes for the seller to receive the order, which was previously seven days to several minutes.

Experience

  • Simple Food Tracker
    https://foodtracker.rohitsaigal.com/

    A full-stack back-end application that allows the user to track food entries.

    Implemented it using React for the front end and Node.js in the back end. I used DynamoDB to persist data, Elastic to deploy my back-end API, and AWS S3 and CloudFront to deploy my React application.

  • Portfolio Website
    https://portfolio.rohitsaigal.com/

    A simple React website to create a portfolio website.

    I used Terraform to help me deploy and created a Terraform module to help spin up a website, certs, and redirects. Deployed using AWS S3 and CloudFront

  • Simle Secure Auth Service

    Designed my own JWT-based authentication system. Created a RESTful API to allow a user to sign up and log in and receive a JWT token, enabling them to communicate securely with the API in future calls.

  • Fulfillment Configurations

    A full-stack web application built for an enterprise eCommerce company managing a growing network of buyers and sellers (10K+), onboarding new users every day.

    The back end was built using Node.js, hosted on AWS (elastic beanstalk/PostgresSgl). The front end was built using React and Sass.

  • Order Workflow engine

    My team was given a task to break down our Order Preparation monolithic service into a microservice architecture. We decided to use a workflow engine design, creating several microservices to manage the order workflow engine. At first, we broke down the Order Preparation into an Order Workflow Microservice and several Data Aggregation Steps that could go through in the workflow (shipment planning, artwork aggregation, etc.) As a side note, we realized that these steps were not as intensive, so we explored the notion of deploying them using serverless infrastructure (AWS lambda).

    Eventually, new buyers/sellers had more requirements for the orders, but instead of modifying the existing system, we could add a new Data Aggregation Step of that particular order, and the order workflow engine would respect it.

  • Order Transmission Service

    Replaced an outdated transmission service that used a queue to manage the state of orders for different sellers of those orders.

    Designed a RESTful system to handle this issue, creating order transmission resources so that each seller could easily manage their order transmissions. This was built using Node.js, AWS Docker deployed Elastic Beanstalk, and Dynamo DB to store the order transmission resources.
