## About

Jan Piotrzkowski is a software engineer specializing in Ruby on Rails, Flutter, and Angular. He has 5+ years of professional experience shipping production SaaS products in fully remote teams. He holds a B.S. in Applied Computer Science from AGH University of Science and Technology in Cracow, Poland.

He is currently a Software Engineer on the Uplisting Core Team at AirDNA, where he builds and ships product features for a short-term rental management platform. Previously, he worked at QuickMail (B2B cold outreach SaaS), Menu.pl (food ordering platform), and Ragnarson (consulting — data-driven cost allocation).

Jan actively integrates AI tools like Claude into his engineering workflow — from code review and debugging to drafting specs and cutting down repetitive work.

Outside of his day job, Jan is building ReadBuildShip — a project to build and ship iOS applications using Flutter and a shared Rails 8 backend. His philosophy is "Read. Build. Ship." — learn by reading, create by building, grow by shipping.
