High-Performance Fundraising Platform with AWS Lambda

A virtual fundraising platform needed a scalable, high-performance solution. It must handle its growing users and seasonal demand changes. We built a serverless system with AWS Lambda, React, and TypeScript. It scales cost-effectively and gives users a great experience.

Challenge

A platform that was expanding quickly faced several challenges:

  • Developing a robust platform to meet the needs of a growing user base

  • Creating a solution that can scale is crucial. Manage distinct high and low seasons. It must handle high loads at peak times and optimize costs in off-seasons

  • Providing a stable development environment

  • Delivering a superior user experience

  • Improving operational efficiency by reducing server maintenance effort

  • Enhancing software testing practices

Solution

We worked with our team to deliver a cloud-based solution. It helped the client improve their platform's performance and scalability.

Backend Architecture with AWS Lambda

  • Maximize the computing capacity of AWS Lambda's serverless architecture.

  • Eliminated the need for server maintenance and management

  • Enhanced operational efficiency

Frontend Architecture with Autonomous React Modules

  • Created a complex frontend structure using autonomous React modules

  • Hosted decoupled, self-sufficient modules on AWS S3

  • Integrated AWS CloudFront for efficient content delivery

TypeScript-Powered Codebase with ReactJS and NextJS

  • Built the entire codebase on TypeScript for enhanced predictability and maintainability

  • Utilized ReactJS for robust frontend development

  • Implemented NextJS to enable server-side rendering that enhances SEO

  • Managed state efficiently using MobX-State-Tree

  • Used Storybook as a UI development environment for creating interactive and reusable components

UI Design System Implementation

  • The purpose of making it was to improve collaboration between designers and developers. Now, everyone uses the same set of tokens. 

Comprehensive Testing Pyramid

  • Implemented a rigorous testing strategy with eight types of tests (e.g. end-to-end testing, unit testing, service testing, contract testing)

  • Achieved an average test coverage of 55% across the testing pyramid

  • Ensured high software quality and reliability

Impact

The implementation of this cloud-based solution led to several business improvements:

Scalable and Stable Platform

The platform handled a growing user base and high transaction volumes without losing performance. It supports 400,000+ unique visitors at peak times.

Cost-Efficient Scalability

Infrastructure costs are below 0.2% of total revenue, under $25,000 monthly for 400,000 unique daily users.

Enhanced User Experience

AWS CloudFront integration cut latency and improved content delivery. It raised user satisfaction and engagement. Plus, it got a 99/100 on Google PageSpeed Insights.

Streamlined Development Environment

Using AWS Lambda for the backend and autonomous React modules for the frontend cut server maintenance complexities. It also provided a stable dev environment and boosted the team's productivity.

Platform Reliability

A comprehensive testing pyramid with 55% coverage and CI/CD pipelines for automated deployments ensured platform stability. This approach reduced critical bugs and enabled efficient update delivery, enhancing overall system reliability.
