Personal OS — what I'm building and why
First post. The shape of the system underneath plantir.garden, posadz.garden, and this blog — and why one operator runs three public sites with one shared schema.org graph.
Software Engineer Blog
Notes from a personal-OS project.
I'm Przemyslaw Gilewski. I run a single-greenhouse telemetry pipeline called Plantir and write here about the engineering underneath — firmware, infrastructure, the bits most blog posts skip.
Sibling properties: plantir.garden (the research dashboard + master's-thesis hub) and posadz.garden (Polish-language consultancy umbrella). This blog is the English-language writing surface that connects them.
