JS FullStack Architect  @ Guesty

In Guesty I had to face many challenges, most of them were in the backend. As the company grew the scale has become a serios issue to address. And we decided to redesign the architecture from a huge monolith to a distributed Microservices architecture.

I led the following changes:

• Design and develop the Web-hooks Microservice and separate it from the monolith.
• Design and develop the queues mechanism by using RabbitMQ and RxJS
• Design and develop the availability Microservice which required a data-migration and an algorithm rewrite
• As a Fullstack developer I challenged with E2E tasks working with AngularJS and React.
