👋 Hello
I’m Junghyun Nam (rkttu), a software engineer with over 15 years of experience, a technical writer, and a community builder.
I’ve been solving complex problems and designing architectures that create business value, primarily based on the Microsoft technology stack. Beyond writing code, I believe in the power of ‘connection’ — sharing knowledge and growing together.
This blog is a space where I document the technical depths I’ve explored and the insights I’ve gained from the community.
🚀 Professional Experience
“I solve problems with code and share knowledge through writing.”
I specialize in C# and the .NET ecosystem, as well as building cloud-native environments with Microsoft Azure. With hands-on experience at companies like Megazone Cloud and Devsisters, I design stable and efficient systems.
