Advanced Kubernetes SRE : Microservices Deployment & Observability -- 2

I am looking for a freelance, "Seeking an expert DevOps/SRE engineer to build a resilient, secure, and highly available platform for three microservices (Node.js, Go, Python) on Kubernetes. The project must cover the full SRE lifecycle, from architecture design to failure simulation."
Key Project Deliverables & Requirements:
Architecture Design: Provide a clear architecture diagram detailing service communication (API, Auth, Image Store) and external dependencies (DB, S3, etc.).

Deployment & Security:

Create Dockerfiles and deploy images to a Private Registry.

Implement robust Network Policies for pod isolation.

Securely manage credentials using Secrets Management.

Set up Ingress with TLS (Let's Encrypt or self-signed).

Advanced Monitoring (Observability):

Implement the Prometheus & Grafana stack.

Configure Custom Metrics for each service.

Integrate Alertmanager with an external notification tool (e.g., Slack).

High Availability & Scaling:

Configure Horizontal Pod Autoscaler (HPA) based on appropriate metrics (CPU, Requests).

Define realistic Liveness and Readiness Probes.

Use PodDisruptionBudget (PDB) to guarantee minimum availability during maintenance.

Failure Simulation & Documentation:

Design and execute failure scenarios (e.g., database downtime, sudden traffic spike).

Document the system's response (logs, alerts, recovery).

Final delivery includes a comprehensive README, all YAML/Code files, the architecture diagram, and a video/report documenting the failure tests.
