From manual deployments to automated CI/CD

CHALLENGE

A Series B fintech startup had outgrown its deployment process. Releases were manual — a senior engineer would spend four or more hours walking through a deployment checklist, babysitting each step. Rollbacks were frequent. There was no automated testing, so defects reached production and were caught by customers. The team was afraid to deploy, which meant they deployed less often, which meant each release carried more change and more risk. A classic death spiral.

The proprietary CI/CD platform they'd been evaluating would have cost a four-figure monthly fee at their scale — a number that made no sense for a startup burning to extend runway. They needed automation, but they needed it without the enterprise price tag.

APPROACH

The decision was to build on Gitea Actions — a self-hosted CI/CD runner that integrates directly with their existing Gitea repositories. No per-seat licensing, no per-build pricing, no vendor lock-in. Codyssey embedded with the customer engineering team: we designed the pipeline architecture and the hard calls on rollback and quality-gate policy, while the team co-built and learned the workflow. Runbooks, decision records, and rollback criteria were captured in the customer's knowledge base so the team could own and improve the pipeline. The approach had four pillars:

• Automated testing pipeline — every commit triggers a full test suite before anything reaches a staging environment. No merge without green tests.
• Blue-green deployment strategy — two identical production environments. New code ships to the inactive one, traffic switches over, and the old environment stays warm for instant rollback.
• SonarQube quality gate — code quality, security hotspots, and coverage thresholds enforced as a hard gate. A build that fails the gate doesn't deploy, period.
• Rollback automation — if health checks fail after a switch, traffic reverts automatically. No human has to wake up and decide.

SOLUTION

A full CI/CD pipeline was built on Gitea Actions, wired end-to-end. The pipeline runs on every push: lint, unit tests, integration tests, SonarQube analysis, build, and — on the main branch — deploy to the inactive blue-green slot. Health checks run for five minutes after switch. If anything drifts outside thresholds, traffic reverts and the pipeline flags the failure with a structured incident report.

The automated test suite was built from scratch — unit tests for business logic, integration tests for the payment flows that mattered most, and smoke tests for the post-deploy window. Quality gates in SonarQube enforced coverage above the baseline and blocked any new critical security hotspots. The rollback automation meant that a bad deploy was a five-minute inconvenience, not a four-hour fire drill.

OUTCOME

Deployment time dropped from four hours to fifteen minutes — and those fifteen minutes are mostly automated health-check windows, not human effort. In the first 30 days of production operation, there were zero failed deployments. Deployment frequency increased 4x, because the team was no longer afraid to ship. Smaller, more frequent releases meant each one carried less risk, which meant fewer rollbacks, which meant more confidence — the opposite of the death spiral they'd been in.

The cost comparison was decisive: the self-hosted Gitea Actions stack ran at a fraction of the proprietary quote, and the savings went back into the product.

The customer engineering team now owns the pipeline day-to-day — adding repositories, tuning test suites, and extending the blue-green logic — while Codyssey remains responsible for the architecture and the hard calls around rollback and quality-gate policy. The runbooks and decision records in the knowledge base let the team self-serve routine changes. By preventing bad releases before they reach production, the pipeline turns deployment from a reactive fire drill into a proactive, low-risk routine.
