About NexisyTech Learning
A free learning space from Nexisy Technologies for engineers who want to understand how real systems are built.
What we teach
NexisyTech Learning covers system design and software architecture end to end: fundamentals such as complexity and latency, scaling techniques, data storage, APIs and security, messaging and microservices, and cloud delivery with CI/CD and Kubernetes.
Every lesson follows the same pattern — a diagram, the key concepts, trade-offs, common mistakes and interview questions — so you can learn a topic in one sitting and come back to revise it quickly.
Who builds it
The lessons are written by the engineering team at Nexisy Technologies, drawing on our work building SaaS platforms, AI products and cloud infrastructure. All text, diagrams and simulations on this site are original NexisyTech content.
Accuracy
Technology changes quickly. Numbers such as latencies are order-of-magnitude guides, and product features vary by version and provider. Always check official documentation before making production decisions. If you spot a mistake, please tell us.
