What will I learn?
The Erlang Course teaches you practical skills to design, build, and run reliable systems that work together at the same time using OTP. You will learn about lightweight processes, sending messages, supervision trees, and call state machines with gen_server and gen_statem. Through practical exercises, you will create call managers, registries, logging, observability, testing, and release processes to deliver strong, fault-tolerant services with assurance.
