Python Concurrency & Async I/O

Software Engineering

You'll unlock the power of concurrent programming in Python. This course demystifies the GIL, threads, and processes, then dives deep into modern asyncio. You will build high-performance, resilient asynchronous pipelines that can handle real-world I/O-bound workloads with ease.

It's an amazing product and exceeded my expectations, helping me prepare for my job interviews. Hands-on learning requires you to actually know what you are doing.

Alex Bush

I'm really impressed by the AI tutor Cosmo's feedback about my code. It's honestly kind of insane to me that it's so targeted and specific.

I tried Leetcode but it was too disorganized. CodeSignal covers all the topics I'm interested in and is way more structured.
