Enhance Github Projects with New Features

I am looking to hire a professional for customizing some Github projects, specifically tailor-making them with design modifications and functionality enhancements. Key details include: - Adding New Features: What I primarily need is to integrate a sign-up/login system into these projects. Your ability to creatively blend this functionality with the existing interface is highly desired. - Building a Live Location Tracking App: Despite this being crucial, I also wish to run a live location tracking application in the final system. Demonstrable experience with similar features would place you at the forefront. Skills and Experience: - Github: Comprehensive understanding and experience with Github projects are vital. - UI/UX Design: Since design modifications are needed, previous engagement with user interface design is appreciated. - Back-End Development: Since we're adding sign-up/login functionality, familiarity with back-end development is required. Consideration for this job won't be solely based on your portfolio diversity, but also your willingness and ability to convert this unique concept into a reality. Looking forward to your proposals.
