Back-end developer and author of the Silay framework
Mahdi builds scalable back ends on Node.js: RESTful APIs with Express and NestJS, data on MongoDB and PostgreSQL, caching with Redis and message queues with RabbitMQ. He is on the team behind a capital-market analysis platform at Part Knowledge-Based Company and has published his own back-end framework on npm.
About

He has worked with authentication, caching, message queues, testing and documentation, and is always looking to build tools that make the team’s work simpler and faster.
