Experience
Supply Chain Management for 7-Eleven
https://www.7-eleven.com/My primary role involved working on a microservice project built using Restify. This microservice was designed to manage the intricate logistics and daily deliveries required for the extensive network of 7,000 stores. Additionally, I was tasked with maintaining critical data integrity by performing routine backups of the production PostgreSQL database. These backups amounted to 10 – 15 gigabytes of data every week, ensuring the continuity and reliability of our system.
The Serverless Architecture Transformation of Ventura
I developed a WhatsApp business channel for IPO stock purchases and instant investment reports. Additionally, I implemented a single sign-on authentication and centralized user login for enhanced security, scalability, and disaster recovery.
Focusing on user experience, I streamlined client onboarding to boost sign-up conversions. I also developed a mutual fund management app back end and a risk assessment system for trade safety and margin calculation, adding value to the organization's services.
Host to Host Application for KOTAK Bank
To address this challenge, I conceptualized an architecture centered around Amazon Elastic Kubernetes Service (EKS) and MongoDB as fundamental components. I then developed the back-end API, which is pivotal in the document processing pipeline. This API was equipped with robust error-handling mechanisms and comprehensive logging capabilities to ensure smooth and reliable operations throughout the entire process and help the support team after deployment to track the process quickly.
SKMD Sports API
The back end was developed using Express (Node.js) and Firestore, and the front end with React. Stripe was used for handling payments, and Firebase Auth was used for authorization and authentication.
An ERP Solution for Bloomstack
https://bloomstack.com/I initiated a proof of concept (POC) utilizing AWS Amplify, AWS AppSync, and Amazon Cognito for front-end authentication and API communication via Next.js applications. Additionally, I worked on an AWS Serverless Application Model template POC for streamlined deployments using the AWS CLI.
I developed AWS Lambda functions for real-time cloud watch event streaming to Elasticsearch, enabling error monitoring and Slack notifications. Integration with the Frappe Framework facilitated data entry form management.
