About

I've spent 16 years in digital marketing - working with major brands across Central Europe. At some point I realized I was better at spotting what's broken in software than at running campaigns, so I started building things instead. Hora is my first serious Swift project. I'm learning as I go, sharing the whole process publicly, and building something I actually want to use every day. Based in Poland, building in public.

Building a native macOS Google Calendar client — solo dev from Warsaw

Hey everyone! I'm Maciej, indie developer from Warsaw, Poland.

I've spent the last few months building hora a native macOS Google Calendar client written in Swift 6 and SwiftUI. The idea came from pure frustration: Apple Calendar drops events via CalDAV, Fantastical costs $60/year, and the web app has zero macOS integration.

hora Calendar - Google calendar built for the Mac

hora Calendar is a native Mac app for Google Calendar. See your next meeting in the menu bar, join Meet, Zoom, and Teams in one click, create events fast, schedule focus time, and sync directly with Google without proxying calendar data through hora servers.

Hi I'm Jeff I'm an acquired founder looking to reconnecting with founders!

After several years of founding and running a VC backed startup that got acquired by a fortune 100 I am looking to reconnect with the founder community!

With AI it's such a fun time to build now, but go-to-market is the new bottleneck. I'd love to connect with folks to share stories!
