Kubernetes/Linux Engineer for support on testing

@ArchnaAdmin

Hi, I have 8+ years of experience as a System Administrator with hands-on expertise in Linux-based web hosting and cloud infrastructure, including server security, monitoring, and performance optimization. I work with Apache, Nginx, DNS, SSL, Cloudflare, and hosting panels like cPanel/WHM, Plesk, and Virtualmin, along with email server setup and marketing environments. I have strong experience with AWS services such as EC2, S3, Route 53, and IAM for scalable and secure deployments, including load balancing and auto-scaling setups. Additionally, I work with Docker, Python, and Kubernetes for building, deploying, and managing containerized applications, including cluster setup, scaling, and production-level troubleshooting. Please share your requirements so we can proceed. Thank you

Kubernetes | Linux | Ingress Troubleshooting | Production Incident Response Hi, I can step in as a production-experienced engineer to validate your Kubernetes environment and give direct, honest feedback on how closely it reflects real-world workflows. I have 15+ years of DevOps/SRE experience, with 6+ years in Kubernetes production environments, including on-call rotations and incident response. I’m comfortable debugging ingress, services, endpoints, readiness probes, DNS, and networking issues using kubectl and system-level tools. I’ve worked with EKS, self-managed Kubernetes (kubeadm/K3s), and Nginx/ALB ingress controllers. I focus on how things are actually handled in production—triage, logs/metrics correlation, rollback decisions, and clear remediation paths. Example incident: Handled a production outage where ingress misconfiguration + failing readiness probes caused intermittent 502s. Traced via logs + endpoints, corrected probe config, and stabilized rollout without downtime. I’m comfortable reviewing workflows critically and calling out what doesn’t reflect real engineering practices. Quick questions: Which ingress controller is in use? Any specific scenarios you want validated? Available for short-term engagement and follow-up. Regards, Rahul

Hi, This sounds like exactly the kind of work I enjoy getting into a system, thinking like a production engineer, and calling out what feels real vs what doesn’t. I come from a Linux-first background and spend a lot of time working close to the system layer debugging, analyzing behavior, and understanding how things actually break in real environments. I’m very comfortable with kubectl, reading cluster state, and tracing issues across ingress, services, endpoints, DNS, and container-level problems. While my Kubernetes journey is still growing in terms of long-term production years, I’ve been deeply focused on understanding how real systems behave under pressure especially from a debugging and reverse-engineering mindset. That means I don’t just follow playbooks; I question them. If something feels artificial or unrealistic, I will call it out clearly and explain what an actual engineer or on-call responder would do instead.

Hi, With extensive experience managing production-grade Kubernetes environments and Linux systems, I am well-equipped to evaluate your confidential technical setup. I possess a deep understanding of Kubernetes ingress, incident response workflows, and production-style troubleshooting (DNS, endpoints, readiness). I am comfortable providing direct, critical feedback to ensure your environment reflects industry-standard engineering practices. My background includes years of on-call experience, allowing me to identify "real-world" gaps quickly. Highlights: Experience: 6+ years in K8s production environments. Incident History: Lead resolution for a major cluster-wide networking outage. Stack: Expert in kubectl, UNIX, and container security. I am ready to sign the NDA and begin immediately.

We will deliver clear, structured feedback along with actionable recommendations to improve the system’s reliability and authenticity.

@vivekprasaths2

Hello, I have ~2+ years of hands-on DevOps experience working with Kubernetes in production environments, primarily on Azure Kubernetes Service (AKS). I regularly work with kubectl, Linux systems, and have strong experience debugging ingress, service routing, DNS resolution, and pod readiness issues. In my current role, I manage microservices deployments on Kubernetes with NGINX Ingress, implement liveness/readiness probes, autoscaling, and handle real-time monitoring using Prometheus and Grafana. I’ve also been actively involved in incident response and root cause analysis (RCA), reducing MTTR through structured debugging and alerting systems. Example incident: I handled a production issue where services were intermittently failing due to misconfigured ingress routing and backend health checks. I debugged using kubectl logs/describe, verified endpoints and probes, and resolved it by correcting ingress rules and readiness probe configs, restoring service stability. I have worked with AKS, NGINX Ingress Controller, Helm, and GitOps (Argo CD) workflows. I’m comfortable reviewing workflows critically and providing honest feedback on whether they reflect real-world engineering practices. Happy to proceed under NDA. And Please ignore the Weekly limit as it was setup by default by freelancer.com As this was my first project in freelancer.com, we can do the negotiation on the pricing as well. Best regards, Vivek

Hi, Happy to sign the NDA and take the review role. 1. Kubernetes experience 8+ years running K8s in production, on top of 15 years in Linux/infra. Daily work on clusters for SaaS platforms (legal-tech, agri-compliance, analytics): deployments, ingress, service mesh, upgrades. 2. On-call and incident response On-call across production for over a decade, including payment and public-facing platforms with tight SLAs. Led post-mortems, written runbooks, worked auth outages, ingress failures, DB failovers and DNS issues. 3. Environments and controllers AKS, EKS, GKE, RKE2 (HA on Claro HPE Omni), k3s, kubeadm on bare metal. Ingress: NGINX, Traefik, Istio Gateway, AWS ALB, AGIC. Mesh: Istio, Linkerd. Observability: Prometheus, Grafana, Loki, Jaeger, SigNoz. 4. Relevant incident Sudden 502s on a customer service after NGINX Ingress upgrade, only on long-lived WebSocket clients. Correlated `kubectl get events` with controller logs — new version changed default `proxy-read-timeout`. Rolled back, then patched ConfigMap with explicit `proxy-read-timeout` and `proxy-send-timeout`. Post-mortem covered the detection gap; added synthetic probe for future upgrades. I give direct, honest feedback. If something feels unrealistic I say so and explain why. Available 0.5–1 day initially, follow-up half-day next week. Weekends fine.
