Subhash Jha

I'm a senior software engineer with 10+ years at Adobe, building creative tools used by millions. Deep expertise in C++ systems programming, image processing, and WebAssembly. Recent focus: generative AI workflows and content authenticity in Photoshop.

Across my career I've shipped features in Photoshop, Illustrator, XD, Dreamweaver, and the Adobe Print Engine. I love problems that sit close to the metal: pixels, performance, and the quiet craft of making creative software feel alive.

Shipping generative AI features in Photoshop and writing about craft, tools, and the small things that make software feel considered. Tinkering with macOS automation, GPU programming, and the occasional weekend web app.
