Observability
Show where Observability affected a real decision in the project. Include the implementation, constraint, test or measurement that makes the skill verifiable.
CAREER PROJECT · Advanced · 2 weekends
Observability + SLO Stack
Instrument a service with logs, metrics, traces, dashboards and an error-budget policy.

WHAT THIS PROJECT PROVES
Make the engineering visible.
This brief is designed as portfolio evidence for a DevOps / Platform path. The goal is not to claim a hiring outcome; it is to make your implementation, judgment and tradeoffs easier to inspect.
SLOs
Show where SLOs affected a real decision in the project. Include the implementation, constraint, test or measurement that makes the skill verifiable.
Metrics
Show where Metrics affected a real decision in the project. Include the implementation, constraint, test or measurement that makes the skill verifiable.
Tracing
Show where Tracing affected a real decision in the project. Include the implementation, constraint, test or measurement that makes the skill verifiable.
Incident response
Show where Incident response affected a real decision in the project. Include the implementation, constraint, test or measurement that makes the skill verifiable.
BUILD PLAN
Finish the core before expanding the scope.
Use this as a project sequence, not a rigid tutorial. Your stack can change; the evidence should still show what you built, why you built it that way and how you know it works.
Define the scope and success criteria
Turn the brief into a small finishable system. Decide what the core Observability + SLO Stack must do, what you will deliberately leave out, and how you will show that it works.
Build the core workflow
Instrument a service with logs, metrics, traces, dashboards and an error-budget policy. Keep the first pass focused on the main user or system flow before adding stretch features.
Add engineering proof
Create telemetry demo and slo definition. Document the decisions, failure states, tests, performance, security or operational tradeoffs that matter for this project.
Ship and package the evidence
Publish the strongest artifacts, including dashboard, alert rules, incident runbook. Make it easy for a reviewer to understand the problem, architecture, tradeoffs and what you personally implemented.
PORTFOLIO PROOF CHECKLIST
Leave artifacts a reviewer can inspect.
A strong project page should make it possible to understand the system without guessing what you personally built.

RESUME / PORTFOLIO FRAMING
Describe what you actually did.
Implemented full-stack observability with service-level objectives, actionable alerts and incident-response documentation.
Use this as a starting structure, then replace it with your real implementation details, metrics and constraints. Do not claim outcomes you did not measure.
INTERVIEW TALKING POINTS
Be ready to defend the decisions.
These prompts turn the project from a repository link into a technical conversation about judgment, tradeoffs and evidence.
Why did you choose your approach to Observability, and what alternative did you reject?
Answer with details from your implementation. Prefer concrete constraints, measurements and alternatives over generic best practices.
Where could Observability + SLO Stack fail under real usage, and how would you detect or recover from that failure?
Answer with details from your implementation. Prefer concrete constraints, measurements and alternatives over generic best practices.
How did SLOs affect the rest of the design?
Answer with details from your implementation. Prefer concrete constraints, measurements and alternatives over generic best practices.
What did you measure or test to prove Incident response instead of only claiming it?
Answer with details from your implementation. Prefer concrete constraints, measurements and alternatives over generic best practices.
If you had one more week, what would you improve first and why?
Answer with details from your implementation. Prefer concrete constraints, measurements and alternatives over generic best practices.
STRETCH GOALS
Go deeper only after the core is solid.
Synthetic checks
Add it only if it strengthens the engineering story instead of delaying a finished, deployable core.
Burn-rate alerts
Add it only if it strengthens the engineering story instead of delaying a finished, deployable core.
On-call simulation
Add it only if it strengthens the engineering story instead of delaying a finished, deployable core.
RELATED PORTFOLIO PROJECTS
Build another signal in the same path.
Choose another project only when it proves a different part of the role instead of repeating the same evidence.
