Hi, I’m Francis 👋

Platform Engineer focused on Kubernetes, AWS, and production-grade infrastructure.

I design and build systems that help teams deploy, operate, and recover applications reliably.

🚀 What I Do

  • Build Kubernetes-based platforms on AWS (EKS)
  • Design CI/CD and GitOps workflows (GitHub Actions + ArgoCD)
  • Implement disaster recovery and backup systems
  • Enforce cost control using FinOps practices
  • Analyze cluster efficiency and resource utilization

🧩 Featured Projects

🔹 Cluster Meter (Core Project)

A Kubernetes capacity analysis tool that inspects cluster resource usage and provides actionable recommendations.

Tech: Go, Kubernetes API, Docker, EKS, ArgoCD, GitHub Actions Highlights:

  • CLI + HTTP API for cluster analysis
  • Real-time capacity metrics and pressure detection
  • Rule-based recommendation engine
  • Containerized and deployed via Kubernetes
  • CI pipeline with linting, testing, and security scanning

🔹 EKS Disaster Recovery Platform

A system that simulates failure and restores Kubernetes workloads using Velero and S3-backed backups.

Highlights:

  • Backup and restore of Kubernetes namespaces
  • Failure simulation (namespace deletion)
  • Full recovery validation with live cluster
  • Zero data loss during recovery test

🔹 FinOps Cost Guardrail Pipeline

A CI-based system that prevents expensive infrastructure changes before deployment.

Tech: Terraform, Infracost, GitHub Actions Highlights:

  • Plan-only Terraform pipeline
  • Cost estimation before apply
  • PR-based cost enforcement
  • Multi-environment cost comparison

🔹 Progressive Delivery Demo

Implements canary deployments and rollback strategies using Argo Rollouts.

Highlights:

  • Canary deployment strategy
  • Controlled rollout progression
  • Failure simulation and rollback
  • Kubernetes-native progressive delivery

🛠 Tech Stack

  • Cloud: AWS (EKS, EC2, S3, IAM)
  • Containers: Docker, Kubernetes
  • IaC: Terraform
  • CI/CD: GitHub Actions
  • GitOps: ArgoCD
  • Languages: Go
  • Observability: Prometheus, Grafana

📌 Current Focus

  • Platform engineering for Kubernetes workloads
  • Improving cluster efficiency and cost optimization
  • Building internal developer platforms
