New course alert The performance of a backend application goes beyond its code and logic. Factors such as network latency, Kernel ... LinkedIn Show all Nasser offers several comprehensive courses, often bundled into recommended learning roadmaps for different experience levels. 1. Backend Engineering Fundamentals This is his flagship series, focusing on how backend applications interact with the OS and network. Fundamentals of Backend Engineering: Covers communication design patterns, protocols (HTTP/1.1, 2, 3), gRPC, WebSockets, and TLS. Troubleshooting Backend Systems: A course on identifying performance bottlenecks using tools like Wireshark and tcpdump to analyze "black box" behavior without looking at code. Real-Time Backend Systems: Explores the unique challenges of building low-latency, bidirectional applications like chat or gaming. 2. Infrastructure and Systems These courses provide the necessary context for high-performance backend work. Fundamentals of Operating Systems: Explores kernel page faults, memory management, threads, and processes to show how they impact application performance. Fundamentals of Network Engineering: Focuses on the "bridge" to the backend, covering the OSI model, TCP/IP stack, and how sockets function at the kernel level. Introduction to NGINX: A practical guide to using NGINX as a reverse proxy, load balancer, and web server. 3. Database Engineering Recognized for its depth, this curriculum moves beyond simple SQL queries to the mechanisms of data storage. Fundamentals of Database Engineering: Covers ACID properties, indexing (B-Trees), partitioning, sharding, and concurrency control. Database-Specific Deep Dives: Includes content focused on Postgres internals and tools like
Hussein Nasser is a renowned software engineer and educator known for his deep-dive approach to the "first principles" of computing. His courses are designed to help developers move beyond simply using tools and frameworks to understanding the underlying mechanics of how systems actually function. hussein nasser courses
