Over nine months, Lerian engineered robust CI/CD automation and release workflows for the LerianStudio/midaz repository, focusing on secure, reliable, and auditable deployments. Lerian implemented GitOps-driven pipelines, automated multi-arch Docker image builds, and integrated security scanning with Trivy to reduce deployment risk. Using Go, Shell scripting, and YAML, Lerian enhanced environment configuration, version management, and notification flows, while introducing AI-powered changelog generation and performance auditing with Lighthouse CI. The work included optimizing onboarding images with multi-stage Dockerfiles and distroless containers, enforcing code quality gates, and streamlining hotfix and beta release processes, resulting in faster, safer, and more maintainable releases.

Sep 1, 2025September 2025 monthly summary for LerianStudio/midaz. Delivered end-to-end GitOps-driven CI/CD automation and a security-conscious onboarding image strategy, enabling safer, faster deployments to development and staging. Key changes include Gitflow-based release workflow with multi-arch Docker builds and integrated security scanning, plus conditional GitOps updates for beta and release candidate tags. Onboarding service Dockerfile was refactored to a multi-stage build using a distroless final image, including migration files. These efforts reduced deployment risk, improved runtime security, and streamlined build/test feedback loops.

Aug 1, 20252025-08 monthly summary for LerianStudio/midaz: Focused on strengthening deployment reliability, code quality gates, and security controls across the CI/CD and GitOps workflows. Key features delivered: - CI/CD Artifact Tag Processing Enhancement — robustly applying image tags to values.yaml by scanning tag files and using a while-loop to ensure reliable tag updates for applications. - Go Code Complexity Threshold Enforcement — increased the gocyclo minimum complexity threshold in golangci.yml from 16 to 18 to enforce stricter code quality. - Security Scanning and Beta GitOps Control — added Trivy-based security scans for Docker images (secrets and vulnerabilities) before pushing to Docker Hub and restricted GitOps updates to beta releases for controlled deployments. Overall impact: Improved deployment reliability and repeatability, stronger code quality gates, and a hardened security posture with controlled release governance. These changes reduce risk in production image deployments and provide clearer gates for feature delivery. Technologies/skills demonstrated: CI/CD automation and tagging workflows, shell-based tag processing in pipelines, Go linting and complexity management (golangci-lint/gocyclo), and container security practices (Trivy) with GitOps governance.

Jul 1, 2025July 2025 monthly summary for LerianStudio/midaz: Delivered a cohesive pre-release CI/CD automation and GitOps pipeline consolidating 12 commits into a repeatable flow across Midaz and Firmino environments. Key capabilities include automated GitOps updates, multi-component image tagging, signing, and embedded security checks, with support for beta vs official releases. The pipeline enables dynamic tag propagation from artifacts and parallel Helm value updates to accelerate releases. A stability improvement was implemented to prevent build-time errors on the develop branch. Impact: faster, more reliable releases with improved traceability and security posture, reducing manual toil and cross-repo coordination while enhancing environment parity and governance. Technologies/skills demonstrated include GitOps, CI/CD automation, multi-repo coordination, Helm, Kubernetes, container image signing, artifact-driven tagging, parallel processing, dispatch-based updates, and security checks.
