Dion Software, LLC is my one-person studio in New York, and the home of my own apps. By day I'm a full-stack engineer at BoldVoice, a Y Combinator–backed startup. Before that, I co-founded WithIn Finance in Germany and spent years embedded in agency and enterprise teams.
A private library for links, notes, photos, files and places. I designed and built it end to end, natively in SwiftUI.
Small Mac utilities that each do one thing and stay out of the way.
200k+TinyStopwatch downloads, with several runs in the Mac App Store’s top 15 utilities
Find and book local photographers by portfolio style, then narrow by location, availability and budget.
I've been writing software for over ten years, from native iOS and Mac apps to Go and PHP backends. I like owning the whole thing: what to build, how it's put together, and keeping it running after launch.
Day to day that means full-stack setups like Next and React or Nuxt and Vue, Node.js and Express on the server, and React Native for mobile apps. Swift and SwiftUI cover native Apple work, and I've built a lot in Go and PHP too, with PostgreSQL, MySQL and AWS underneath.
A Y Combinator–backed accent training app for non-native English speakers, pairing lessons from Hollywood dialect coaches with instant feedback from speech AI. 5M+ downloads.
A research platform and social network for shareholders, across web, backend and mobile. It later grew into Diyfolio, portfolio optimisation for DIY investors, and RoboRente, a retirement planner.
With V2A.NET, GMF and teams across Europe and the US. The products are real and shipped, but they carry the client’s name.
Questions about one of the apps, support, or anything to do with the company: email is the quickest way to reach me.
