    I am looking for Sr. React Native and Android Developer. I have a react native project built with Expo, typescript. But I couldn't publish app to google store, because android sdk version is 30 which means it's not compatible on google store. All features are completed as well and iOS has been already submitted. So I think Expo version should be upgraded to the latest version. It's very urgent to me and I want to publish android as soon as possible. As long as android sdk version is 31 or higher, I can get app published on google store. I am looking for someone who can handle this problem shortly. Please apply if you did upgrade Expo versions successfully before

    I have built a PDF document in adobe and I need the document to have data entered, a user sign it and then send the next person in the chain who will need to do the same. I would like it to be saved to a shared folder and then sent the next person in line using an automated task based on information in the document. I think Java is the best way to do this based on what I understand and have read. I also need the document to require fields to be completed prior to it being signed and some of those fields are drop downs, but they are drop downs and I don't want the default one to count as it being completed. I also would like a way to track where the document is in the chain.

    Hi, Hello, I have created an Android App that organises online contest after every one hour or less than that in which e.g, every contest has 50 spots and about 25 or more winners. Users have to pay entry fee and when then contest period is over (contest countdown), the system automatically declare the winners. I came to know that this type of game (game of chance) is illegal in India. Now I want to add some little bit skill to it so that becomes legal as 'game of skills'. Freelancer should add changes to backend admin panel (php) also. NOTE: I have no idea of what skills need to add, you have to give idea of that
