Experience

Driver Application | Low Cost Parcels

http://lowcostparcels.co.uk

This macOS app enables a user to create custom labels for HDD collections. With this app, a user can print a set of labels with custom project images, company logos, and auto numeration for video production companies.

Escape-the-room Control Room Software | Extremescape

This is a macOS application for escape-the-room experiences. The application was developed to provide multiple experience theme image sets, a room timer, and one-way communication with players in the room.

PDF Audio Annotations Library

Developed back in 2014, this library was made to add audio annotations to PDF files to corporate iOS software. Although the format itself supports various objects in files, built-in iOS libraries are quite limited in that area. I developed this iOS library based on a C PDF library and it became a great solution there, enabling users to comment documents with their voice.
