Rafael Jaén Profile

Hi, I’m Rafael— a Full Stack Web Developer from Andalucía, Spain.

I build real-world .NET applications and write about C# and software architecture in ways that are practical and easy to apply. My focus is on clean, maintainable code and building systems that scale without adding unnecessary complexity.

Through this blog and newsletter, I share lessons learned from real projects, practical tips, and insights that help developers write better code and make smarter design choices. The content is aimed at engineers who want to understand how things work and improve their craft, not at those looking for generic advice.

I’m also building in public at codeinspain.com, a tech job board for Spain’s developer community. You can explore my work and learn more about my projects on my personal website rafita.me.

If you want to follow my work, explore my projects, or discuss software and architecture, you can connect with me on X. I focus on sharing knowledge that makes development more effective and enjoyable, without unnecessary noise.
