I build things in cycles — Blender addons, Unreal Engine plugins, web apps, and hardware prototypes — then write fantasy novels in the gaps. Based in County Westmeath, Ireland with my wife Gené and our five daughters.

About

Builder by nature.
Storyteller by calling.

I'm an independent developer, fiction author, and homeschooling father of five daughters, based in Mullingar, County Westmeath, Ireland. I operate under Siler Technology — a one-person studio that ships tools and projects across multiple disciplines.

My work spans Blender addons, Unreal Engine 5 plugins, single-file web apps, hardware prototypes, and the Sky Bridge Saga — a multi-book steampunk fantasy series co-authored with my sister Allyson Siler.

I build in cycles. Each project gets full attention until it's done, then I move to the next problem worth solving. Everything is made to be useful, playable, or both.
