I run production infrastructure and private AI systems on servers you own — Proxmox, Docker, Kubernetes, and self-hosted LLMs that keep your data out of the cloud. If your server is down or your platform needs deploying, I've got you. Day to day I run real production environments — not lab setups: Proxmox clusters, 15+ virtual machines, a K3s/Rancher Kubernetes cluster, Docker deployments, and CI/CD pipelines across multiple products. I work comfortably from the hypervisor up to the reverse proxy. What I do: - Server troubleshooting & recovery — Proxmox, Linux, VPS. Down server back online, root cause found, not just patched. - Docker deployment — Docker Compose, Nginx/Traefik, SSL, CI/CD with GitHub Actions. - Kubernetes — K3s + Rancher in production: Traefik ingress, cert-manager, persistent storage, tested backups. - Migrations — provider-to-provider, VPS consolidation, VMware → Proxmox. - VPN & networking — WireGuard, NetBird, OpenVPN, site-to-site setups. - Self-hosted apps — Nextcloud, n8n, Odoo and more, deployed securely and built to last. - Monitoring — Prometheus + Grafana + Alertmanager for production visibility. - AI/LLM infrastructure — Ollama, self-hosted models, GPU setup, n8n AI agents and workflow automation. - Windows Server & Microsoft 365 — Active Directory, Entra ID, tenant administration. Recent client work: full production stack for a Luxembourg medical practice (Nextcloud, n8n, DocuSeal, self-hosted LLM — patient data never leaves their server), and a two-site Proxmox + Proxmox Backup Server deployment for a US client. How I work: I treat your server like production — because it is. I verify the traffic path and check logs before changing anything, I document what I do so you understand it, and I never make silent changes that could break access. You get a fix that holds, plus a clear explanation of what happened and why. For clients who want peace of mind, I offer monthly server management — proactive monitoring, security updates, backups, and priority response, so problems get caught before they become outages. Tools: Proxmox VE, Proxmox Backup Server, Docker, Docker Compose, K3s, Rancher, Nginx, Traefik, GitHub Actions, Linux (Ubuntu/Debian), WireGuard, NetBird, PostgreSQL, MySQL, Redis, Prometheus, Grafana, n8n, Ollama, Let's Encrypt, fail2ban, systemd. → Tell me what's broken or what you're building — I'll tell you exactly how I'd handle it.

Cloud Security & DevSecOps Engineer for teams running on AWS, Azure, GCP, BigQuery, ETL, and CI/CD. I help teams secure cloud infrastructure, data pipelines, and deployment workflows without slowing engineering down. That includes IAM, Entra ID, vulnerability assessment, security analysis, CI/CD hardening, DevSecOps, and information security work across the full environment. Most clients come to me when things already feel messy. Access is too open, cloud infrastructure has grown without clear security rules, CI/CD is moving fast without enough guardrails, and nobody is fully sure where the real risk is. That is exactly why they hire me. I do not just point out issues. I work on the actual infrastructure, access model, cloud setup, and delivery flow so your team can reduce risk, stay organized, and keep shipping with more confidence. 𝙎𝙚𝙧𝙫𝙞𝙘𝙚𝙨 𝙄 𝙊𝙛𝙛𝙚𝙧: 𝟭. Cloud Security Reviews: I review cloud infrastructure, identity, networking, permissions, workloads, and data flows to find real security gaps and give clear priorities. 𝟮. DevSecOps & CI/CD Security: I secure CI/CD workflows so teams can build, test, and deploy with better controls, fewer mistakes, and less production risk. 𝟯. IAM & Entra ID Hardening: I improve IAM, Entra ID, roles, permissions, least privilege, and access design so the right people get the right access without unnecessary exposure. 𝟰. Vulnerability Assessment: I run vulnerability assessment work, validate findings, remove noise, and help your team focus on what actually matters. 𝟱. Security Analysis: I break down risks in plain English so leadership, engineering, and operations can understand what is wrong, what matters most, and what to fix first. 𝟲. Cloud Infrastructure Security: I help secure infrastructure in AWS, Azure, and GCP, including compute, networking, storage, identity, and deployment patterns. 𝟳. Data Engineering & ETL Security: I support secure ETL flows, BigQuery environments, and data architecture decisions where access, movement, storage, and control of data matter. 𝟴. Information Security Support: I help teams improve their information security setup with practical controls, documentation, clearer ownership, and cleaner processes. 𝟵. Quality Assurance for Security Changes: After fixes are made, I verify that the changes actually work and that the environment is more secure, stable, and easier to manage.
