About

Building functional, high-quality apps that are smooth, performant, and fun to use. I care about the details — animations that feel *just right*, accessibility beyond screen reader support, and small touches that make interactions more enjoyable.

Always up for a good UI challenge and often find ways to put math and geometry to good use (see: Modulaser, Odio, but also things like Metal shaders).

I build with SwiftUI and other Swift frameworks for Apple platforms, as well as React for the web.

Projects

2024

Responsible for building two consumer-facing clients for MuseHub, a platform offering audio-related digital products like apps, plugins, and sample packs.

Developed the macOS app in SwiftUI and built the web client from scratch using Next.js, focusing on high performance and a seamless user experience to support many thousands of daily users.

2024

Reimagined my Apple Design Award-winning app Odio for spatial computing, creating an immersive experience as a launch-day app for Apple Vision Pro.

Users can place sound-emitting 3D ornaments in their surroundings, creating an immersive spatial audio experience.

Featured in the App Store’s "The Best Apps for Apple Vision Pro" collection.

2023

Created an iOS app that makes 3D scanning free and accessible for anyone. Built with SwiftUI, SwiftData and Apple’s Object Capture API.

2022

Designed and developed the Duux mobile app, bringing smart functionality to their indoor air treatment devices. Focused on creating a smooth, inviting user experience with fluid animations and an interface that feels great to use.

2021

Helped Tango build and launch its initial product, laying a strong foundation for scalability. Focused on core UI functionality, improving usability, and ensuring a performant, accessible experience.

Worked closely with their small, focused team to refine the app into a polished, market-ready product.

2021
Odio

Co-created Odio, an app that lets users immerse themselves in interactive spatial audio soundscapes, helping them focus, relax, or sleep.

Led interaction design and development, building a framework for dynamic sound interaction with head tracking. Designed an intuitive UI that makes exploring spatial audio effortless and engaging.

Winner of an Apple Design Award.

2021

I developed The Ocean Cleanup's mobile app in React Native. The app enables volunteers to easily track and report the amount of plastics and other waste in rivers, seas and oceans. The collected data helps track pollution levels worldwide, supporting cleanup efforts in rivers, seas, and oceans.

2019

Created Modulaser, a macOS and Windows app for creating abstract visuals for show lasers and performing live with them. Inspired by modular synthesizers, it lets users create patches and interactively manipulate visuals—treating laser artistry like a musical performance.

Since its launch, Modulaser has become a staple for laser VJs worldwide, remaining just as relevant today as when it was first created.

2022

“The audio app Odio delivers incredibly lifelike ambient sounds — waterfalls, rushing rivers, lush electronic washes — made even more realistic with Spatial Audio and head tracking. Soundscapes can be customized by manipulating their mixes through a captivating circular interface, and each one is accompanied by futuristic fluid animations that unfold in perfect synchronicity with the sound. It’s a truly amplified take on the audiovisual experience.”

Features

2024

Designed and built a custom iPad app for an interactive sound installation at the Bang & Olufsen x ADER ERROR pop-up event in Seoul.

2024

“Odio, which uses Spatial Audio and intuitive gestures to display beautiful 3D images in a user’s space for focus, relaxation, or peaceful sleep.”
