Hi, I'm Omar Essaouaf, a Senior Software Engineer passionate about building scalable systems, distributed architectures, and AI-powered applications. I specialize in PHP (Laravel, Symfony) and TypeScript (Node.js, Express.js, NestJS), with experience designing microservices, cloud-native services, data ingestion pipelines, and semantic search systems at scale. On this blog, I share practical insights on backend engineering, software architecture, performance optimization, and AI based on real-world projects and lessons learned in production.
