The Challenge

Running approximately 200 Drone CI jobs per hour for Go microservices across a Hetzner VM fleet. Infrastructure was provisioned manually, CI pipelines lacked security scanning, and container images were unsigned. Scaling was becoming painful, and there was no visibility into supply chain security.

What We Built

Migrated infrastructure to Terraform + Ansible for reproducible VM provisioning
Re-architected Drone CI pipelines with parallelization and caching optimizations
Integrated Trivy for vulnerability scanning in every build
Implemented Sigstore (Cosign) for container image signing
Set up SBOM generation for all artifacts
Deployed Prometheus + Grafana for CI/CD observability
Created automated alerting for pipeline failures and security issues

Technology Stack

Drone CI Terraform Ansible Hetzner Cloud Go Docker Trivy Sigstore/Cosign Prometheus Grafana

Security & Compliance

  • Vulnerability scanning integrated into every pipeline
  • Container images cryptographically signed with Sigstore
  • SBOM generated for every build artifact
  • Secrets moved to HashiCorp Vault (no credentials in Git)
  • Pipeline access restricted with RBAC

The Results

40% faster CI pipeline execution through optimization

100% of container images now signed and verified

Zero manual infrastructure provisioning (full IaC adoption)

Complete vulnerability visibility across all builds

Team can confidently scale to 500+ builds/hour

Why catdev?

The client needed a team that understood both high-velocity CI/CD and supply chain security. Generic DevOps consultants would have optimized pipelines but missed the security gaps. catdev delivered both speed and security without compromising either.

European Bank Migration to Azure

Legacy on-premises infrastructure running critical banking services. Jenkins pipelines were fragile and undocumented. Migration to Azure Cloud required meeting strict regulatory compliance (PSD2, GDPR, local data residency). Team lacked cloud-native expertise and needed a secure, compliant landing zone.

  • Successfully migrated 15 critical banking services to Azure with zero downtime
  • Achieved PSD2 and GDPR compliance certification

U.S. Bank Core Banking Exchange Pipeline

Building a new core banking transaction exchange interface (NDA-protected details). No existing CI/CD pipeline for this greenfield project. Extremely high compliance requirements (PCI DSS, SOC2, FFIEC). Needed end-to-end pipeline with full audit trails, secrets management, and deployment automation for a highly sensitive transactional system.

  • Delivered production-ready pipeline meeting all PCI DSS and FFIEC requirements
  • Zero security findings during external audit
