About Kelvin Ducray

Software, consulting, and a few quieter interests. This page is the front door to the things I build, write, and think about.

I'm Kelvin Ducray — a software engineer focused on backend systems. Most of my professional work happens under Aetherisys Consulting, where I help teams ship greenfield backend software.

Outside of that, I tinker with health and training, build small tools for myself, and occasionally write things up. This portal is a single page that points at all of those threads as they come online.

You can also find Kelvin on GitHub, LinkedIn, X, and Instagram.

If you're looking for the consulting side specifically, the right place to start is aetherisys.consulting.
