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
Technologies Used
A modern tech stack built for scalable and efficient impact. The frontend used React and Next.js. AWS powered the backend and infrastructure. TypeScript ensured code quality. React Native will enable cross-platform mobile development in the future.
The workflow
Our goal: develop a flexible, long-term solution tailored for virtual fundraising and e-commerce. We balanced scalability with specific business requirements well.

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.
