Work Experience
Back-end Software Engineer
2022 - PRESENT
Zomentum
- Developed integration with Autotask to export real-time changes from the portal to Autotask. Used Scala as back-end language and AWS SQS as a change notifier while using documented REST APIs to push real-time data.
- Converted a third-party integration from SOAP to REST whereby accommodating the integration APIs latest changes and reducing the call time from four to two seconds.
- Implemented webhooks from Autotask wherein any change made will come into the system instantaneously, leading to cleaner and more accurate data at all times for the user. Developed webhook consuming API in scala.
- Developed a feature wherein a user can add comments to their documents, which will be shown to the user's client in real time, leading to faster communication. Used MongoDB and Scala to implement the feature.

Software Engineer
2020 - 2022
Cimpress
- Created a cache management system using AWS SQS, Node.js, and AWS Lambda to clear the pricing cache of products whenever pricing is updated in bulk. This reduced the time to invalidate the cache by 70% leading to a dynamic pricing update.
- Added campaigns and product discounting prices functionalities in the website using Node.js, TypeScript, and AWS DynamoDB. Used Docker image on AWS Fargate to update prices in countries at midnight to make campaigns live or expire them.
- Built a dashboard to show and allow a set of users (who have permissions) to update the availability and technical features of products on the fly using Node.js, TypeScript, SQS, and SNS.
- Converted the linkage of an accessory to a product from the SKU level to a product level to make the actual product API call faster by over 50%. Wrote the script in Node.js and code changes in TypeScript.

Experience
Railway Concession Automation System
Built an application that automates the process of obtaining the rail concession for college students. Developed a module for students, one for colleges, and one for railway authorities. The platform updates students through email on the status of their applications.
Used Node.js as the back-end language and MySQL as the database.
Used Node.js as the back-end language and MySQL as the database.
Cache Clearing Lambda
Created a cache management system using AWS SQS, Node.js, and AWS Lambda to clear the pricing cache of products whenever pricing is updated in bulk as a part of the back-end team at Cimpress. Whenever the admin team updated bulk prices, a notification per product was sent to SQS, triggering lambdas in parallel with the maximum rate the database could absorb. Each triggered lambda individually cleared the cache of multiple 3rd-party services along with the actual database. This reduced the time to invalidate the cache by 70% leading to a dynamic pricing update.
Integrated Autotask CRM
Developed integration with Autotask to export real-time changes from the portal to Autotask as a part of back-end team in Zomentum. Created a trigger on entity update on our portal, sending a message to AWS SNS, which notifies AWS SQS queue. A lambda was developed as a listener to the mentioned queue, which updates the entity in Autotask using their REST APIs. Used Scala as a back-end language for this project.
