Experience

Cruise Company

The project is a mobile application for cruise company passengers. The application includes an offline map, offline notifications, GPS, purchases, and media content. The target audience uses both iPhone and Android devices, so the app should be released on both platforms simultaneously and have a consistent appearance. There are very tight deadlines because the cruises start in April, and the application needs to be available by then.

Power Cut-off Detector

https://github.com/lantushenko-alex/smarthome-controller
A pet project that can be shared with anyone. The primary feature is to detect grid power-off events. There are no reliable devices on the market that can cope with this. A mobile phone with the app installed should be plugged into a power outlet. If grid power goes down, the application sends a message via a Telegram bot.
