This product is a sophisticated image and video processing app, and it allows you to create professional-looking photos and apply interesting effects with a few taps. This product was built from scratch, and I've had the privilege to lay down technological foundations and implement around 90% of the product over the course of two years.
- Social Network Apphttps://steamrole.org
A role model-based social network designed for students and aspiring young professionals to discover top careers that match their interests and get inspiration and guidance from successful professionals. As an iOS engineer on this project, I got an existing codebase, implemented new features, and provided maintenance for existing ones.
