What will I learn?
The Erlang Course equips you with practical skills to design, build, and run reliable concurrent systems using OTP. You will learn about lightweight processes, message passing, supervision trees, and call state machines with gen_server and gen_statem. Through hands-on labs, you will implement call managers, registries, logging, observability, testing, and release workflows to deliver robust, fault-tolerant services confidently.
