I’m Marian Posăceanu, a software developer working primarily with Ruby, Rails, PostgreSQL, APIs, search and systems performance.

I build open-source developer tools and write about what I learn. On Ark, I publish technical investigations into software, macOS and Apple silicon, with measurements, sources and practical limitations. My Dot-files site documents the terminal tools and workflows I use.

Away from code, my interests include music, audio and philosophy. Online, you may also know me as dakull.
