I am Jun Kurihara, a research engineer in the area of distributed systems and networking in Japan and sometimes in US. I am really interested in developing novel software and networking products/services written in various languages on various infrastructures. You can reach me via my LinkedIn or WebSite.
rpxy [ahr-pik-see] is an implementation of simple and lightweight reverse-proxy with some additional features. The project is (always and endless) work-in-progress, but being used in numbers of production environment. rpxy supports the brand-new HTTP/3 standard, ACME with TLS-ALPN-01 out-of-the-box, and the TLS post-quantum key exchange by default.

rpxy is an HTTP, i.e., layer-7, reverse proxy. On the other hand, rpxy-l4 is a brand-new layer-4 (TCP/UDP) reverse proxy with protocol multiplexer functions, e.g., IETF-QUIC, TLS, SSH, Wireguard, etc. rpxy-l4 is also being developed along with rpxy and designed from the philosophy of rpxy, i.e., simple and lightweight.
Currently I am really interested in the enhancement of privacy-preserving DNS architectures. As one of my research activities, I am actively developing Mutualized Oblivious DNS by extending existing sophisticated encrypted and anonymized DNS protocols.
