Petrodweep Case Study

A high-scale petrol pump SaaS platform built with frugal serverless architecture

Overview

Petrodweep is a multi-tenant SaaS platform built for the petrol pump and fuel retail industry. It supports operational workflows, inventory management, transaction logging, reporting, and mobile-enabled field processes in a highly scalable and cost-efficient architecture.

The system was designed to scale from zero with near-zero idle costs while being capable of supporting very large operational rollout.

The challenge

Fuel retail operations involve significant complexity:

  • Multiple business workflows
  • Inventory and reporting needs
  • Transaction-heavy usage
  • Operational visibility
  • Mobile usage in field environments
  • Historical data migration
  • Multi-tenant software requirements
  • Future national-scale growth expectations

The challenge was to build a platform that could handle all this complexity while still being cloud-cost efficient.

Our solution

Technodweep built Petrodweep as a strictly serverless, multi-tenant platform using:

  • NestJS
  • AWS Lambda
  • SQS
  • CloudFront SaaS Manager
  • DynamoDB Single-Table Design
  • ReactJS
  • React Native for iOS and Android

The architecture was designed to deliver strong scalability, low idle cost, and operational robustness.

Advanced data architecture

One of the most sophisticated aspects of Petrodweep is its DynamoDB design.

The platform uses:

  • 37 logical tables
  • Inside a single physical DynamoDB table
  • With an LSI-only design
  • Strong consistency
  • Predictable access patterns
  • Excellent cost efficiency

This approach allowed us to support complex industry workflows without falling into expensive or fragile database patterns.

Migration and scale readiness

As part of the project, Technodweep migrated 8 years of historical data into the platform, totaling nearly 500,000 rows.

The system has been engineered from day one to support very large-scale growth and is architected with the vision of serving up to 80,000 petrol pumps in India.
