Namshi is an e-commerce company based in Dubai that has grown to over 250 employees and serves millions of visitors per month. Originally using a monolithic PHP architecture, they migrated to a microservices architecture using PHP, Node.js, RabbitMQ, and other tools to improve scalability, deployability, and maintainability. This involved breaking the monolith into independent services, implementing an event-driven messaging system, and building new frontends using JavaScript.

of designing software applications
as suites of independently deployable services…”
