Multi-Vendor Marketplace
Microservices Architecture for Multi-Vendor Commerce
Built a multi-vendor commerce platform around a 12-service microservices architecture, with Next.js, NestJS, MySQL, Stripe payments, recurring billing, and AWS infrastructure.
Project Overview
A Marketplace Is More Than an Online Store.
A multi-vendor marketplace has more moving parts than a conventional single-store commerce application. The platform needed a backend architecture capable of separating business responsibilities while supporting commerce workflows and payment operations.
Multi-Vendor Complexity
Multiple business responsibilities needed to coexist within one commerce platform.
Service Separation
The backend needed to be organized into independently structured services rather than becoming one increasingly complex application.
Payment Operations
The platform needed reliable Stripe Checkout integration, webhook handling, and recurring payment workflows.
From One Commerce Platform to Twelve Focused Services
The platform was structured as 12 microservices, with NestJS providing the backend foundation and Next.js powering the frontend experience.

- MICROSERVICES
- PAYMENT INTEGRATION
- AWS DEPLOYMENT
Twelve Services. One Marketplace.
The backend was divided into 12 microservices, creating a distributed architecture for the marketplace rather than concentrating the entire system inside a single backend application.
Architecture Should Solve a Problem.
The marketplace was structured around 12 microservices to separate the system's backend responsibilities into focused services.
Separation
Break a complex commerce platform into focused backend services.
Maintainability
Keep responsibilities isolated instead of allowing the backend to become one increasingly complex codebase.
Independent Structure
Give distinct areas of the platform their own service boundaries.
One Entry Point. Twelve Services Behind It.
The API Gateway provided a central routing layer between the frontend application and the distributed backend services.
Payments Designed Around Stripe.
Stripe Checkout was integrated into the marketplace to handle payment flows, with webhooks used to process Stripe events and recurring payments supported as part of the billing experience.

Commerce Beyond the First Transaction.
In addition to one-time Checkout flows, the platform supported recurring payments through Stripe.

- STRIPE
- WEBHOOK
- BACKEND
Built for the Cloud.
The application was deployed on AWS, providing the cloud infrastructure behind the marketplace platform.
Technology Choices With a Reason.
NestJS
Structured backend foundation for the distributed service architecture.
Next.js
Frontend application framework for the marketplace experience.
MySQL
Relational database layer supporting the application.
Microservices
12-service architecture for separating backend responsibilities.
Stripe
Checkout, webhook processing, and recurring payment capabilities.
AWS
Cloud infrastructure for the deployed platform.
The Complexity Was in the System, Not the UI.
The core engineering challenge was coordinating a multi-vendor commerce product across a distributed backend, payment workflows, recurring billing, and cloud infrastructure.
Distributed Architecture
12 backend services needed to form one coherent product.
Payment Integration
Stripe Checkout and webhook-driven payment processing needed to integrate with the application.
Product Complexity
The marketplace combined multiple commerce responsibilities within one platform.
Lead Developer & SME
Architecture
Contributed to the design and implementation of the 12-service microservices architecture.
Backend Engineering
Worked with NestJS across the distributed backend.
Payment Engineering
Implemented/integrated Stripe Checkout, webhook handling, and recurring payment capabilities.
Technical Leadership
Worked as Lead Developer & SME within the five-person team.
Engineering Quality Doesn't Always Control Business Outcomes.
The business ultimately did not succeed commercially. The project nevertheless demonstrates the engineering work required to design and build a complex multi-vendor platform within a four-month delivery window.
