Integrated Cloud, Serverlesss & Infrastructure Work

• Built and deployed serverless backend components using AWS Lambda, powering event-driven workflows and API endpoints without managing servers.
• Integrated AWS SQS with Lambda for scalable asynchronous processing — including a high-volume SMTP email management pipeline using SQS for queuing, throttling, retries, and reliable message handling.
• Utilized AWS S3 for secure storage, static asset hosting, backup management, and system log archiving across multiple applications.
• Managed traditional compute workloads using AWS EC2, deploying and tuning backend services before transitioning to a serverless-first architecture.
• Implemented Infrastructure as Code (IaC) using Terraform to automate provisioning of AWS resources used by these systems.
• Used Ansible for server configuration, automated deployments, and environment consistency across development, staging, and production.

Dishout (Food Ordering System)

• Designed and developed the backend for a comprehensive food ordering system consisting of four major components:
• Merchant side (tablet app) for restaurants, shops, and grocery stores to manage their offerings.
• Customer side (mobile app) enabling users to browse and place orders.
• Driver side (mobile app) for drivers to handle deliveries.
• Admin side (web app) for system-wide management and monitoring.
• Implemented microservices architecture, ensuring scalability and modularity.

Influencer Stock Exchange Application

• Developed the backend for a web application that allows investors to buy stocks based on influencer performance metrics from social media platforms (TikTok, Instagram, YouTube).
• Integrated external APIs to periodically assess the stock value of influencers.
