Rebuilt from scratch and maintained a mobile app for managing smart business cards with NFC and QR code integration. Fixing bugs, adding features, publishing new releases to the store etc. The tricky part about the project was making pretty much everything easy to change on the go without publishing a new release to the stores (socials image, categories, order of the sections, adding new socials etc.) If you want to try the app out, you can order a card here and create an account. https://shop.e-lit.ro/en/shop
