The Brief
What you'll do, and what you'll demonstrate.
Build a unikernel-based WireGuard exit-node prototype and assess viability against a Linux baseline on boot time, footprint, throughput, and operational cost.
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
- Understand unikernel design (library OS, single address space)
- Reason about the attack-surface vs operational-cost tradeoff
- Benchmark network throughput rigorously (saturation, percentiles)
- Recommend a kernel-architecture path that respects ops reality
