Emmanuel Restrepo Rancruel

Infrastructure & Automation Engineer

I build scalable systems, automate workflows, and handle real-world traffic.

My journey started with a game...

~2010|Age 12

Curiosity Phase

What started as gaming curiosity quickly turned into a deep interest in how systems work under the hood. Experimenting with memory manipulation and packet-level analysis built an early foundation in reverse engineering and problem-solving.

  • Memory manipulation and process analysis with CheatEngine
  • Packet-level experimentation and game protocol understanding
  • First exposure to client-server architecture concepts
  • Self-driven learning without formal guidance
Cheat Engine
I wanted to understand how everything worked behind the scenes.

Server Administration

Built and operated private game servers from scratch — configuring web servers, managing databases, and deploying full-stack applications. Learned PHP, MySQL, and server administration through hands-on production experience.

  • Deployed and maintained game servers with IIS and XAMPP
  • Built admin panels and CMS in vanilla PHP
  • Direct MySQL operations: data migration, content management, manual queries
  • Modified C# server emulators (Phoenix Emulator) to extend functionality
  • Managed Flash (.SWF) asset pipelines and content updates

Before I could legally work, I was already managing servers and databases.

Security Fundamentals

Explored offensive security to understand how vulnerabilities work. Hands-on experience with SQL injection, database extraction, and web application security testing built a strong foundation in defensive security practices.

  • SQL injection testing and database extraction techniques
  • Web application vulnerability assessment
  • Understanding of common attack vectors and mitigation strategies
  • Security-first mindset developed through real-world experimentation
I learned to attack so I could understand how to defend.

Production Infrastructure

Managed production infrastructure handling 1,000+ concurrent users with real revenue at stake. Operated dedicated servers, implemented payment processing, and built DDoS mitigation — all with zero tolerance for downtime.

  • 1,000+ concurrent users on dedicated OVH infrastructure
  • Multi-server architecture: partitioned and interconnected dedicated servers for load distribution
  • Stripe payment integration with real transaction processing
  • DDoS mitigation and uptime guarantees — revenue depended on availability
  • Full commercial operations: billing, support, infrastructure

At 17, I was managing infrastructure with real money and thousands of users.

Modern Stack

Continuously evolving with the technology landscape. From VPS management to containerization, from PHP to Python automation, from Flash to modern React-based systems. Every platform shift was an opportunity to expand capabilities.

  • VPS management across DigitalOcean, OVH, and Contabo
  • Linux server administration and web hosting deployment
  • Docker containerization and Proxmox virtualization
  • Python scripting and workflow automation
  • React Native mobile development
  • Email server configuration and DNS management
  • Twilio API integration for communications
  • Adapted through Flash→React migration: learned from community codebases, resolved migration issues, built custom UIs
