Systems & Infrastructure Architect

I build at the intersection of system administration and application architecture, refusing to treat infrastructure as a black box. I design the foundations: hardening Linux environments, orchestrating containerized workloads, and building the networking layers that keep services reachable and resilient.

Infrastructure & Operations

  • Systems: GNU/Linux (Debian, RHEL), Systemd, Bash.
  • Orchestration & CI/CD: Docker, GitHub Actions, Automated Deployments.
  • Networking & Security: NGINX, Wireguard, ufw/iptables, OAuth2/JWT.
  • Cloud: AWS (EC2/S3), Aruba Cloud, VPS Management.

System Design & Backend

  • Architecture: Designing event-driven systems and secure, scalable API layers.
  • Data: Database modeling and performance tuning with PostgreSQL.
  • Implementation: Building distributed services using Python (FastAPI) and TypeScript (Node.js), with experience in enterprise-grade Java (Spring Boot).

Communication

  • 🇮🇹 🇷🇴 Bilingual: Italian & Romanian.
  • 🇪🇸 🇲🇽 Professional: Spanish (C1).
  • 🇬🇧 🇺🇸 Professional: English.
