Throttle - build a safe Go HTTP client
A complete beginner can build and explain a bounded Go client, token and leaky buckets, safe retry policy, observability, and operational tests through sixteen cumulative stages. Completion is not a job-readiness guarantee.

About this path
Unbounded clients can overload dependencies, leak resources, or duplicate side effects during retries. Build rate controls and retry behavior from first principles, with local behavioral evidence and explicit operating limits.
What you will learn: Go HTTP clients, Rate limiting, Retry backoff, Concurrency, Client observability. Build the project through cumulative challenges with beginner explanations and local verification.
- Level
- Complete beginner to independently building and operating the project
- Format
- 16 cumulative challenges; plan 4-8 weeks at 8-12 hours per week, including practice, debugging, and a final operational exercise
- Before you start
- No Go or HTTP experience required. A terminal, text editor, Git, and a supported Go toolchain are introduced in the first stage; the optional paired agent requires Python 3.11+, GitHub CLI, and an authenticated fork.
