Hi, I’m Joaquin “Shyan” Crespo (ShyanJMC)
Senior Systems Architect & Cybersecurity specialist from Argentina 🇦🇷

I work at the intersection of low-level systems, cloud security, and open-source infrastructure. My background spans Rust, Linux, Kubernetes, DevSecOps, and multicloud security architectures (AWS, Azure, GCP), with a strong focus on secure-by-design systems, resilience, and performance.

What I’m working on

• RavnOS – a minimalist, secure operating system written in pure Rust, focused on ARM64, low resource usage, and resilience

• Open-source research in:

  • Secure system design
  • Cloud-native security tooling
  • Infrastructure hardening
  • AI integration in systems engineering

• Long-term technical projects combining OS development, distributed systems, and security automation

Why sponsorship matters

Your support directly enables:

• More time dedicated to open-source development
• Hardware for low-level systems research (ARM boards, lab infra, testing environments)
• Documentation, tooling, and educational resources
• Long-term sustainability of projects like RavnOS

Sponsorship is not about donations — it’s about funding independent engineering, research, and tools that stay open, free, and technically serious.

Focus areas

• Rust systems programming
• OS development
• Cybersecurity & DevSecOps
• Cloud security architecture
• Kubernetes security
• Infrastructure resilience
• Applied research & technical education

If you believe in open infrastructure, secure computing, and engineering-driven open source, your support helps turn research into real, usable systems.
