PCB Designer//IT Infrastructure//Mechatronics Eng.
Mechatronics Engineering student at CETI (graduating 2026), specializing in the intersection of high-complexity PCB design and secure IT infrastructure. Fluent in English & Spanish.
I design multi-layer boards with signal integrity in mind, and I build the infrastructure to support them — from Proxmox hypervisors to Zero Trust network segmentation via OPNsense. My homelab runs 24/7 on my own hardware.
This portfolio is hosted on my own Proxmox VE server: Ubuntu Server VM, Nginx reverse proxy, tunneled via Cloudflare — zero open inbound ports.

Designed and hand-assembled a mixed-signal PCB integrating an analog sensor front-end with digital processing. Includes SMT reflow and manual BGA rework.
Collection of 15+ designs spanning power delivery networks, sensor interfaces, motor drivers, and embedded MCU breakouts — across Altium, KiCad, Eagle, and OrCAD.
Bare-metal Proxmox VE on Cisco rack servers with RAID 6 storage. Virtualized OPNsense handles Zero Trust segmentation across multiple VLANs.
Microservices via Docker Compose on Debian. Nginx reverse proxy routes from Cloudflare Tunnels — zero open inbound ports, production-grade uptime.
This site runs on a VM inside my Proxmox cluster: Ubuntu Server, Nginx, and a custom Python backend — all tunneled through Cloudflare with WAF rules active.
