I'm Grigory, a product engineer.
I lead engineering at SQUAKE. Companies book their travel through agencies; we collect that data, turn it into reporting they can actually use — spend, travel patterns, emissions — and buy and retire the carbon credits that cover it. Nine years of Rails and payments, mostly at startups. I live in Barcelona.
Evenings I build my own things. Right now that's Omas Cloud, a metrics backend, Siftbase, which turns messy file uploads into clean datasets, and Waytale, AI audio guides for city walks.
I write mostly about shipping under pressure: the shortcuts, and whether they were worth it.
