The Brief
What you'll do, and what you'll demonstrate.
Rewrite a single-threaded IoT gateway to use async message-passing and scale from 200 to 500+ sensors per box without losing messages under load.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Apply asyncio patterns (tasks, bounded queues, worker pools) to a real device
- Implement message-passing with backpressure correctly
- Benchmark CPU + memory + loss rate at scaling points
- Document async-design choices the firmware team can extend
