Scalable Marketplace Platform Case Study

Project Overview

Our client, a successful regional e-commerce business, faced significant scaling challenges with their monolithic platform as they expanded globally. Increased traffic and transaction volumes strained the existing architecture, impacting performance and growth.

Grabasoft redesigned their digital infrastructure, transforming the legacy system into a modern, scalable microservices-based marketplace platform capable of handling millions of users and thousands of vendors worldwide.

Key Challenges

Migrating from monolith to microservices without disruption
Implementing auto-scaling for unpredictable traffic
Creating a distributed database strategy for global catalogs
Developing a robust API gateway for vendor integrations
Building a resilient multi-currency payment system
