Hi, I'm Harry Hogg.
A fullstack engineer, with 13 years experience building software
The last +3 years I've been working at Spotify. The previous 7 years were spent working at startups in Brighton and London within various industries. Before that, for 2 years I was shipping jQuery and PHP over FTP (it still counts).
I've worked all parts of the stack; product, design and engineering. I've lead 5 design system projects, Scala dataflow pipelines, a Rust network tiling search and renderer system, a realtime collaborative book editor, GIS infrastructure management, a drag and drop email editor, WebGL, Canvas and SVG infrastructure visualisations used by Netflix, internal engineering platforms, and the desktop application at Spotify.
