I architect, deploy, and manage highly available cloud environments and AI infrastructure for enterprise clients. As a cross-domain infrastructure architect, I bring end-to-end stack ownership to complex deployments—bridging the gap between bare-metal systems, cloud-native orchestration, and application-layer integrations. With deep, specialized expertise in RedHat/Fedora ecosystems, OpenStack, and Kubernetes, I deliver scalable, fault-tolerant solutions engineered for strict SLAs. My broad technical background allows me to seamlessly integrate databases, networking, and custom backend code into cohesive, production-ready systems. Recent Architectural Deployments: * Engineered and deployed enterprise OpenStack environments on GCP utilizing Kolla-Ansible. * Designed and implemented Retrieval-Augmented Generation (RAG) chatbots for high-level data integration and automated ingestion. * Developed custom, high-performance AI agent frameworks leveraging Crystal and Go. * Executed complex, zero-downtime infrastructure migrations into KVM/Qemu virtualized environments for enterprise and non-profit sectors. Core Engineering Stack: * Cloud & Virtualization: OpenStack, Kubernetes (Kubeadm, Ingress, Longhorn), KVM/Qemu/Libvirt, Docker, Podman. * Systems & Automation: RedHat/Fedora/CentOS, Systemd, Puppet, Bash, Kolla-Ansible. * AI & Backend Integration: Python, Go, Crystal, LLM integration, RAG architectures. * Storage & Security: Ceph, GlusterFS, SELinux, firewalld, iptables. * Web & Database: Nginx, Apache, PostgreSQL, MariaDB/MySQL. I build resilient systems that scale across the entire stack. Let's discuss the technical requirements and architecture of your next deployment.
