THE CHALLENGE
Legacy bugs & tech debt – Core endpoints produced intermittent 5xx errors that were hard to reproduce.
Low observability – No centralized logging or KPIs to diagnose issues.
Glacial releases – Manual regression testing meant a six-week deployment cadence.
Knowledge gaps – Sparse documentation made it painful for new hires to contribute.
BetterTrucks needed a reliable, observable, and testable API layer—without halting daily operations.

THE SOLUTION
1 • Stability First
Error budget defined: target ≤ 0.01 % failed requests.
Hot-path refactors in C# (.NET 7) eliminated race conditions and N+1 queries.
MySQL tuning (indexing, read replicas) cut P95 response times by 38 %.
2 • Test Automation & Coverage
Introduced xUnit + FluentAssertions for unit tests; SpecFlow for integration scenarios.
Built a contract-test harness to validate external partner integrations on every PR.
Reached 85 % coverage, catching regressions before they hit production.
3 • Observability & KPIs
OpenTelemetry instrumentation piped metrics to Datadog dashboards: latency, error rate, throughput, and deployment health.
SLO alerts in PagerDuty give ops a 15-minute lead on customer impact.
4 • Continuous Delivery
GitHub Actions workflow runs linting, build, tests, security scan, and blue-green deploy to AWS ECS.
Feature flags let product managers toggle functionality without redeploying

THE OUTCOME
Five-nines mindset: 99.99 % uptime sustained over the last 90 days.
Deployment velocity tripled: shipping every 2 weeks with near-zero rollbacks.
Confidence at scale: Automated suite prevents 75 % of previously recurring production bugs.

Testimony
“NetForemost turned our Core API from a black-box liability into a measurable, high-velocity asset. We ship more often, break less, and sleep better.”
