Project
SLO platform
Reliability-driven- Defined SLIs and SLOs for critical services.
- Tracked error budgets and burn-rate alerts.
- Helped teams balance reliability and release velocity.
Why this project is valuable
Strong SRE signal
An SLO platform shows you operationalize reliability with SLIs, error budgets, and burn-rate alerting, the core SRE practice.
Good ATS coverage
The project naturally supports SLO, SLI, error budget, Prometheus, burn-rate, and reliability keywords.
Clear reliability relevance
Balancing reliability against velocity is exactly what SRE hiring managers want to see.
Good interview depth
You can discuss SLI selection, SLO targets, burn-rate windows, alerting, and how budgets influenced release decisions.
Project overview
An SLO and error budget platform is strong site reliability engineer resume material because it shows you can make reliability measurable and use it to drive engineering decisions, not just react to outages.
The platform defines service-level indicators from real telemetry, sets SLO targets, computes error budgets, and configures multi-window burn-rate alerts so teams know when to slow down and protect reliability.
On a resume, that gives you concrete ways to describe SLI selection, SLO target setting, error budget policy, burn-rate alerting, and how the platform shifted release decisions toward reliability.
Architecture overview
Project flowService telemetry
Latency, error, and availability metrics are collected from services as SLI signals.
SLI definition
Indicators like success rate and latency percentiles are defined from telemetry.
SLO targets and budgets
SLO targets set acceptable reliability and define the consumable error budget.
Burn-rate alerting
Multi-window burn-rate alerts fire when budget is consumed too quickly.
Error budget policy
Budget status informs whether to ship features or focus on reliability.
Reliability dashboards
Dashboards show SLO compliance and budget burn for each service.
What this project includes
- Telemetry-based SLI definitions
- SLO targets and error budgets
- Multi-window burn-rate alerting
- Error budget policy for release decisions
- Reliability dashboards per service
Tech stack
This stack is practical for SRE hiring because it operationalizes reliability with real metrics and alerting, not just aspirational uptime goals.
Prometheus
Collects SLI metrics and evaluates burn-rate alert rules.
Grafana
Visualizes SLO compliance and error budget burn.
Sloth
Generates SLO and burn-rate alerting rules from definitions.
Terraform
Provisions monitoring and alerting configuration as code.
PromQL
Expresses SLI queries and burn-rate calculations.
Alertmanager
Routes burn-rate alerts to the right on-call teams.
Features implemented
Measurable reliability
SLIs and SLOs turn vague uptime goals into concrete, trackable targets.
Error budgets
Budgets quantify how much unreliability is acceptable before action.
Burn-rate alerting
Multi-window alerts catch fast and slow budget burn without noise.
Release policy
Budget status guides whether teams ship features or focus on reliability.
Per-service visibility
Dashboards show compliance and burn for each critical service.
Config as code
Terraform-managed SLOs keep reliability definitions consistent.
Resume bullet examples
These bullets show how to present SLO work as operationalized reliability rather than 'set up monitoring.'
- Built an SLO and error budget platform defining SLIs from telemetry and SLO targets for critical services with Prometheus and Sloth.
- Configured multi-window burn-rate alerts so teams were notified of fast and slow error-budget burn without alert fatigue.
- Established an error budget policy that guided whether teams shipped features or prioritized reliability work.
- Built Grafana reliability dashboards showing SLO compliance and budget burn per service, managed as code with Terraform.
Skills demonstrated
This project demonstrates strong SRE skills for SLO design, error budgets, burn-rate alerting, and reliability-driven decision making.

Practice
ATS keywords extracted from this project
Use keywords that reflect reliability engineering practice, not only the monitoring tool name.
Interview questions based on this project
SLO projects often lead to questions about SLI choice, alerting design, and using budgets to drive decisions.
How did you choose SLIs?
I picked user-facing indicators like request success rate and latency percentiles that reflected actual customer experience rather than internal resource metrics.
Why multi-window burn-rate alerts?
Multi-window alerts catch both fast severe burn and slow steady burn while limiting false alarms, which single-threshold alerts cannot.
How did error budgets change behavior?
When a service exhausted its budget, the policy shifted focus from features to reliability, making trade-offs explicit and data-driven.
How would you improve it further?
I would add SLO-based capacity planning, automated budget reporting, and dependency-aware SLOs for composite services.
Common mistakes
Explain SLIs, SLOs, and error budgets so it sounds like reliability engineering.
Choose user-facing indicators, not just CPU or memory, for credible SLOs.
Discuss burn-rate windows so alerting sounds intentional and low-noise.
Show how budgets influenced release decisions for real impact.
FAQ
Is an SLO platform a good SRE resume project?
Yes. It demonstrates the core SRE practice of measurable reliability, error budgets, and burn-rate alerting.
Do I need production traffic?
A demo service with synthetic load works for a portfolio, as long as your SLIs and burn-rate alerts are real.
Should I mention burn-rate alerting?
Yes. Multi-window burn-rate alerting is a strong signal of mature SRE thinking.
How many bullets should I use for this project on a resume?
Usually two to four bullets. Focus on SLI design, error budgets, and decision impact.
