With 20+ years of hands-on experience, I help businesses deploy scalable, secure, and cost-efficient systems using Proxmox, Kubernetes, and cloud platforms like AWS & Azure. In addition to infrastructure, I work as a Full-Stack Engineer, building and scaling SaaS applications end-to-end — from frontend dashboards (React / Next.js) to backend APIs (Node.js / Python), and data architectures using PostgreSQL, Redis, and analytics engines. I specialize in solving complex system challenges across both application and infrastructure layers — from designing complete cloud-native platforms to optimizing performance, data pipelines, and fixing critical production issues under pressure. menos -
