Hello, We are a startup in stealth and want to create the equivalent Web version to our existing Android app which functionality is already completed. All the back-end is already done too, and the Android version can serve as an easy guideline of what needs to be implemented in JS/web. What you need to do is code the web version mostly with JAVASCRIPT (and CSS/HTML). As the app involves ENCRYPTION, you would need to be familiar with it, as well as know how to identify and use the right libraries. There are 2 immediate needs: - a simplified web version that allows people who have our mobile App installed to interact with non-registered users via a link/webpage. - the full web version of the app. Looking forward to your resumes/proposals. Fyi we've several other iterations of the app planned, and if you are qualified, we'd love to build a long term relationship with you and give you more work. Best regards, Jesus
