Summary

Production Kubernetes platform with GitOps-driven delivery pipeline. Automated scaling, comprehensive observability, and infrastructure-as-code across multiple environments.

Problem

Manual deployment processes, configuration drift between environments, and limited visibility into production health created reliability risks and slowed delivery velocity.

Constraints

  • Multi-environment consistency (dev, staging, production)
  • Zero-downtime deployments required
  • Full audit trail for all infrastructure changes
  • Cost-aware: auto-scaling must respect budget limits

Architecture

Kubernetes clusters managed via Terraform, with ArgoCD providing GitOps-driven continuous delivery. Prometheus + Grafana stack for observability. All configuration stored in Git as the single source of truth.

Key decisions

  • GitOps over CI/CD push: Git as single source of truth eliminates configuration drift and provides full audit trail
  • ArgoCD over Flux: Stronger UI for team visibility, better multi-cluster support
  • Terraform for infrastructure, Helm for workloads: Clear separation between infrastructure provisioning and application deployment

Outcome

Reliable multi-environment platform with GitOps delivery. Deployments went from manual multi-hour processes to automated, auditable, zero-downtime rollouts.

Stack

Kubernetes, ArgoCD, Terraform, Helm, Prometheus, Grafana, GitHub Actions

I’ve spent 20 years building systems across embedded firmware, security platforms, fintech, and enterprise architecture. Today I focus on production AI systems in Go — multi-agent orchestration, MCP server ecosystems, and the DevOps platforms that keep them running. I care about systems that work under pressure: observable, recoverable, and built to last.
