Roll Out OpenTelemetry Tracing Across a Microservices Fintech
Overview
What this challenge is about.
Roll Out OpenTelemetry Tracing Across a Microservices Fintech. Advanced challenge in code. Writing production code that solves real engineering problems, ear...
The Brief
What you'll do, and what you'll demonstrate.
Roll out OpenTelemetry tracing across 12 fintech services with a defensible sampling and cardinality policy that the platform team will operate.
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
- Adopt OpenTelemetry SDKs across multiple runtimes consistently
- Design a Collector topology that scales beyond a pilot
- Define tail-based sampling that keeps the right traces cheaply
- Operate a cardinality budget so observability cost doesn't spiral
Program Fit
