Food ordering application aimed on US market. From selecting place through scheduling order time and picking dish to reordering, orders history etc.
This one is the most rewarding feature I've coded recently. It was a part of the food ordering application - during reordering food flow. I'm very proud of it because thanks to my work the flow got shorten and each user saves about one min. every time. To be honest it wasn't challenging or super complex but IMHO it had a huge impact on people's lives.
