Complete one bounded exercise and leave with evidence: a working resource, executable test, recovery observation, or architecture artifact.
Cloud lifecycle lab
Use the AWS CLI to create a uniquely named bucket, upload one object, inspect what exists, and remove every resource you created.
You will leave with
A complete create → inspect → verify → clean up workflow that leaves no lab resources behind.
Reliability lab
Create a small Deployment in an isolated namespace, expose it internally, delete a Pod deliberately, and observe the controller restore the desired replica count.
You will leave with
First-hand evidence of desired state, replica replacement, scaling, Service selection, and namespace cleanup.
Quant correctness lab
Implement a tiny moving-average strategy, lag the position by one bar, and add assertions that fail when the backtest accidentally trades on information from the same close.
You will leave with
A reproducible toy backtest with an explicit signal/position boundary and automated look-ahead checks.
Architecture workshop
Turn a product brief into capacity estimates, an API contract, a delivery pipeline, and a failure strategy for email, push, and in-app notifications.
You will leave with
A reviewable one-page design with explicit scale assumptions, idempotency boundaries, retry rules, and delivery-state ownership.
