Description

Network Architect & Full-Stack Systems Engineer (Go/Node.js)

Bio: Need a network that guarantees 99.9% uptime or a real-time application that handles data with zero latency? I help businesses build secure, scalable, and high-performance connectivity solutions.

I bring a unique "hybrid" value to your project: the discipline of mission-critical industrial engineering (Railway Telecoms) combined with the agility of modern cloud-native development (Telemedicine Platforms).

Core Services:

Network Architecture: Cisco Routers, Switches, Firewalls, IP/MPLS, OSPF, BGP.

System Development: Golang, Node.js, WebRTC, REST APIs.

Infrastructure: GCP, Linux Administration, Virtualization, Edge Computing.

Diagnostics: Wireshark Analysis, QoS Optimization, Security Audits.

I speak the language of hardware, software, and international business (English, Spanish, French, Arabic). If you need technical precision and a problem-solving mindset, let's talk.

Option 3: The "Bullet-Point" (Best for Quick Scanning)

Best for platforms where clients skim quickly.
