Peter Stojanowski's profile on Product Hunt

About

I'm a senior engineer and I've been shipping iOS apps since 2011: fifteen years of mobile, desktop and web, plus the backends behind them. Most of it client work, including six years on Ford's connected-vehicle apps and projects for the BBC, ITV and Burberry. The apps I make on my own are why I'm here. Metrochrome is a film darkroom, and the successor to BLACK, which I shipped on iOS and Windows Phone years back; that is probably why I still care about Metro. Invoice.app handles invoicing for freelancers and small businesses. I work alone or embedded in a team, and I'm available for new projects.

Metrochrome - A pocket darkroom. Every film is a measurement

A darkroom in your pocket. Load a roll, develop it, print from it — on film that is measured, not imagined: 36 emulsions digitised from the makers' own datasheets. Print with an enlarger head, ring-around, test strip, dodge and burn. Every film is free.
