Namhyeon Go (Catswords)
Hello. I am Namhyeon Go, leading a one-person software team known as Catswords in South Korea.
I develop and share a variety of open-source projects through GitHub, including frameworks, middleware, and sometimes debugging tools. My key projects include ReasonableFramework (based on PHP), WelsonJS (based on Windows ECMAScript, with C#), and Caterpillar Proxy (based on Python). Recently, I have been actively exploring and contributing to open technologies and protocols such as WebAssembly and ActivityPub.
Through my opensource work, I strive to make these technologies widely accessible to everyone, independent of any specific organizations or financial interests.
Sponsorship is vital for maintaining and enhancing the security standards and quality of my opensource projects while ensuring that I am not reliant on specific organizations or financial interests. Additionally, it enables me to stay current with the latest trends, ensuring that my projects meet the industry's evolving requirements. Sponsorship also helps me connect with a broader community.
If you are interested in exploring sponsorship methods, please feel free to reach me.
