Experience
- Tinge - Retro Filters
Tinge is an app for filtering photos and videos with color. All filters were created by myself, along with the app, inspired by old school design and fashion aesthetics.
Tinge has been listed by Apple as an "artistic app" inside the App Store's "Photo and Video" page. - Reverse Music Player
A fully featured backward player. Record or play songs from the music library backward to find hidden messages or just have fun. I implemented the backward functionality from scratch by manipulating the song file with AVFoundation.
- Sweet Photo Booth
A simple photo booth app for the iPhone, which I developed and designed.
- Soundgramrhttps://soundgramr.wordpress.com
Soundgramr is no longer available, but it was an interesting idea I tried to develop: a camera app that records the environment sounds as you snap a picture. Later on, you could "listen" to the picture.
- Rearrange - Photo Collagehttps://apps.apple.com/us/app/rearrange-photo-collage/id1046594188
Rearrange builds upon iOS aesthetics to deliver a unique idea: a collage app that has only one screen. By using gestures and motion effects, Rearrange lets you create and modify photo collages intuitively.
