$30-250 USD

Paid on delivery
I have an existing Java application. I'd like you to use the existing libraries in the application and call new REST services (its already calling other REST services. ) I have all the services that it needs to call documented in Postman and ready to share. You just need to create the POJOS and implement the calls in the program. The REST calls will return a list of data. I'd need you to implement a database that persists the data when the program is not running and can be backed up periodically. I don't care what type of DB you use. I also want all file input/output from the existing app where it is writing to static files, to write to the DB instead of the files. This is probably only 4 or 5 files. I'd like to be able to admin the DB, so that if I need to I can create and edit new tables easily.

Hi there, I have about 15 years of experience in java, spring , hibernate and a host of other frameworks. I have a lot of expertise on web services both rest and soap and with data persistence in different databases both relational (MySQL, oracle)and non relational (mongo, Hadoop). Can you please suggest how you would be deploying your application. Is it on physical device or in the cloud . That would help me choose the database. Also, as per the project description it appears that the tables need to be aligned with the rest apis. Can you please confirm. Well I almost got into solutioning mode!! Request you to kindly consider my proposal and we can take it further from there. Regards, Rabiya
