Piotr Sarna is a Polish software engineer at Turso (and previously at ScyllaDB), focused on distributed-database internals. He has co-authored material on the engineering side of writing about software for technical audiences.
His CourseFlix listing carries Writing for Developers — Blogs that Get Read — a course on the technical-writing craft for software engineers: turning the engineering blog post, internal documentation, and conference talk into a deliberate skill rather than an afterthought.
Material is paid and aimed at engineers ready to make their technical writing land with the audience they're writing for. For broader content, see CourseFlix's Soft Skills & Communication category page.
