Your server's down at 3am. Your cloud bill doubled. Deploys are a Friday nightmare. I fix exactly this โ€” fast, with a rollback plan for every change. Results from 49 completed projects (100% Job Success): - 99.9% uptime โ€” real monitoring with Prometheus, Grafana, and structured alerting - 30-60% faster page loads โ€” Nginx/Apache tuning, CDN, TLS hardening, HTTP/2 - 20-35% lower cloud costs โ€” right-sizing, autoscaling, lifecycle policies, FinOps - Deploys in minutes โ€” Docker, Kubernetes, GitOps (ArgoCD/Flux), GitHub Actions, GitLab CI What I do: - Infrastructure & Containers: Linux, Docker, Kubernetes, Helm, Terraform, Ansible - Cloud: AWS, GCP, Azure - CI/CD: GitHub Actions, GitLab CI, ArgoCD, blue-green/canary deploys - Monitoring: Prometheus, Grafana, OpenTelemetry, ELK/OpenSearch - Security: Vault, SBOM/SLSA, Zero Trust, WireGuard/OpenVPN - Scripting: Bash, Python, Go, PowerShell How I start: 1. Quick audit (30-60 min) โ€” what's running, what's breaking, what costs money for no reason 2. Prioritized action plan โ€” what to fix now, what can wait, rollback strategy for every change 3. Early wins in 48 hours โ€” faster response, fewer alerts, lower bill, working backups I don't do "two weeks of discovery." I dig in, find the worst problems, fix them fast. Tell me what's hurting โ€” I'll be straight about whether I can help and what it takes.

I help businesses and homelab enthusiasts deploy secure, reliable environments using Docker, reverse proxies, VPNs, and automation. My experience includes designing and securing self-hosted infrastructure, troubleshooting servers, automating deployments with Bash/Python, and implementing security best practices inspired by real-world security experience. I can help with: โ€ข Docker & Docker Compose deployments โ€ข Traefik / NGINX reverse proxies โ€ข WireGuard VPN setup โ€ข Linux server administration โ€ข Security hardening โ€ข Bash automation โ€ข Infrastructure troubleshooting โ€ข Self-hosted applications โ€ข And More (I can always learn) I believe good infrastructure should be secure, documented, and easy to maintainโ€”not held together with quick fixes. If you're looking for someone who communicates clearly and treats your infrastructure like it's their own, I'd be happy to help.

Struggling with unreliable infrastructure, VMware licensing costs, or a stalled cloud migration? I'm a DevOps & Cloud Engineer who builds and stabilizes production environments across AWS, Azure, Proxmox, and Ceph โ€” with a focus on uptime and automation. Most DevOps engineers specialize in either cloud or on-prem infrastructure. I do both: I've run production Proxmox VE clusters with Ceph storage alongside AWS, Azure, and GCP deployments, and I handle VMware-to-Proxmox migrations end-to-end โ€” a combination few freelancers on Upwork cover with hands-on production experience. Here's how I typically help clients: โœ” Design and deploy cloud infrastructure on AWS, Azure, or GCP โœ” Build and troubleshoot Proxmox clusters, including VMware-to-Proxmox migrations โœ” Optimize and recover Ceph storage clusters โœ” Set up Docker and Kubernetes environments with CI/CD pipelines โœ” Implement monitoring with Zabbix and Grafana โœ” Plan and test backup and disaster recovery strategies โœ” Secure infrastructure with VPNs, firewalls, and Zero Trust practices Top Rated Plus on Upwork with a 4.98 rating across 51 completed jobs and over 2,870 hours worked. AWS Cloud Practitioner Essentials certified. Clients include startups, MSPs, SaaS companies, and enterprise teams relying on me for production-grade infrastructure. Send me a message with what you're working on and I'll respond with next steps within a few hours.
