Your task will be to develop an Android App with a Laravel server-side Backend / Administration, that allows me to manage my service staff and jobs.

(2) Employees install app and signs up Now the employees can sign up using their assigned code. (3) Adding & Assigning Jobs From the backend I can now add jobs (name, address, phone-number, to-do list a la Google Note) and assign them to one or multiple employees. Depending on the chosen employees I see their agenda (when they are free) and set the appointment for the job.

This ad is for individual freelancers. No companies please. We are looking for experienced Android developers to work on our existing application. We have some big code changes in the pipeline, and we need someone who can take the lead on it - I have less and less time now to give it enough attention, and we are looking for a pro to take it to the next level. If you are a strong and confident developer who loves clean code, and you have some experience behind your belt, we need you, and we are prepared to pay higher rates. We need someone who is comfortable navigating a legacy code base. The work will involve adding new features, while cleaning up the code base, and doing refactors. If you are comfortable ripping others code apart, you will fit right in. This is an ongoing hourly job, and we are pretty flexible, but we need a minumum of 20 hours per week, so please don't apply if you have other commitments which will not let you meet this. Your first task will be a small...
