Hey there, we're Daniel and Daniel

We've been building iOS and web apps since 2010 and we'd love to work with you.

About us

We’re senior freelance developers based in the SF Bay Area, currently available for remote work from October 2020 onwards.

We build native iOS and Mac apps in Swift, though we’ve got the background to work with Objective-C codebases too. For full-stack web apps we use Rails and React.

We’ve worked with big names like Lyft and Google, startups like Triplebyte and zyBooks, and small businesses like Augie and Duco. We’ve published about a dozen indie projects of our own, and over the years our work has been featured in the App Store multiple times.

On a more personal note, the two of us met in pre-school and we’ve been close friends since. It’s a dream come true to support ourselves by building high-quality apps together.

Our Tech Stack


Selected Projects



When we’re not working on freelance projects, you’ll find us working on our latest personal project, Keysmith.

Keysmith lets you create custom keyboard shortcuts for your Mac (and the web).

We built the Mac app with Swift and SwiftUI. The website was built with Rails and React. And the browser extensions are vanilla JavaScript.

We also did all the product and design work for Keysmith using Figma.
