This repository documents my hands-on learning journey in Cybersecurity, Cloud Computing, and Artificial Intelligence.
Each project represents applied learning --- taking concepts from documentation, courses, and certifications and implementing them in real environments.
The goal is to build a portfolio that demonstrates:
- real infrastructure deployment
- secure system design
- automation and CI/CD
- AI‑augmented engineering workflows
A project exploring AI‑assisted QA automation workflows using Playwright + Claude Code.
This experiment demonstrates how an AI‑driven pipeline can transform a Product Requirements Document (PRD) into a working Playwright test suite and maintain it when UI changes occur.
Workflow demonstrated:
- Planner Agent → converts a PRD into a structured test plan
- Generator Agent → produces deterministic Playwright tests
- Healer Agent → repairs failing tests caused by simulated UI drift
Highlights:
- Playwright test suite for the SauceDemo demo application
- Simulated locator drift and AI‑assisted repair
- Version‑controlled workflow separating stable automation
(
main) from experimental healing scenarios - Real debugging examples (test ID mismatch and brittle currency assertions)
Future phase:
Converting the suite into Playwright CLI playbooks for agent‑driven browser execution.
A fully automated GitHub Actions CI/CD pipeline that provisions, configures, and tears down a production-grade Kubernetes cluster on Oracle Cloud Free Tier — $0/month vs $250+ on AWS EKS.
Infrastructure as Code stack: Terraform (OKE cluster, VCN, compute, storage) + Ansible (VPN provisioning, DNS configuration) + Helm (application lifecycle).
Security model: All workloads are VPN-only. A WireGuard server on a free AMD instance acts as the sole ingress path for n8n, pgAdmin, and Grafana. TLS certificates are issued via cert-manager with Cloudflare DNS-01 challenge — no public exposure of services or challenge endpoints.
Kubernetes hardening applied per workload:
- RBAC with least-privilege service accounts
- NetworkPolicy (default-deny, explicit allow)
- HPA with CPU autoscaling (metrics-server)
- ResourceQuota + LimitRange per namespace
- PodDisruptionBudget for n8n workers
Applications deployed:
| App | Notes |
|---|---|
| n8n v2 | Queue mode — webhook listener + workers backed by Valkey |
| PostgreSQL | StatefulSet with block volume persistence |
| pgAdmin | Database management, VPN-only |
| Prometheus + Grafana | kube-prometheus-stack, emptyDir (stays within Always Free storage cap) |
| Cert-Manager + Ingress-Nginx | Wildcard TLS via Cloudflare DNS-01 |
