    Stay away from this freelancer. This project has been a disaster. It was accepted 4 months ago and I have yet to get to the first milestone. What's worse is I was stupid and put down $3,000+ to start the work, which he refuses to refund any portion of. I've been shown some work after I voiced my anger with the situation, it was good work, but no where near what should have been complete in 4 months time. Yuri does not keep his word, goes days without responding, and is dishonest at times. After paying $3k down payment, he asked me for an additional $1500 to buy his girlfriend a car! And that was before showing any progress! Stay away. I wish I had. Shame on Freelancer.com for not helping me get any money back.

    Duo did a fantastic job on our project and went above and beyond when we asked for some changes to be made. The project took a little longer than we originally anticipated but this was due to holidays and a mismatch of scheduling and we completely understand and were fine with it. Duo was always available for communication and was very thorough in his work. We would definitely hire him again!!!

    WHAT I NEED: iOS, Android Mobile App & Admin BackEnd and FrontEnd Website - - **** Programmer must be willing to fix bugs within 60 days of completion. Ideally I would want this done within 4-5 Weeks. ******The premise for this mobile application is relatively simple. The app will primarily be used for users to set up their own profile and keep track of important personal accomplishments, upcoming events, and to interact with other members on the app.First, users should be able to quickly register their own user name and password. Once doing this they should (if they choose) be automatically logged-in under that profile upon opening the app.Secondly, members will be asked a few questions to set up a profile and this data will also be used to help them track some things for them. It should include fields (some optional) such as Name, Gender, Location, Anniversary Date, Hobbies, Upcoming Events, etc.Ever app Dashboard only needs a menu with 3 or 4 sub-sections. (1) My Profile (2) Inbox (3) Calendar (4) Search(1) My Profile: A place to view & edit your personal information (see above) and change the privacy settings on your account.(2) Inbox: A clean easy to navigate page showing Received Messages and Send Messages that can be expanded upon clicking.***(3) Calendar: *IMPORTANT - A page where the admin of the app can constantly update upcoming events. When posting an event there should be fields for (a) Event Name (b) Event Date/Time (c) Event Location (d) Event Description (e) Contact Details. Also when a member is viewing different events he should have the ability to click an icon that will add it to his/her personal calendar. Also it should have an icon that will allow him to share this event via Email or Text Message.***(4) The Search Page: a way for existing members to search (with optional Search Filters) for other members (who choose to be listed publicly) and also send messages directly. After finding other members you should be able to click on their page and Add Them To A List or Send Them A Direct Message. Search filters should include Location (GPS feature?), Age, Gender, Anniversary Date, etc...I would also like the same features to be available on a regular website that is all based off of the same database. The admin(s) should have have permissions to assign other members permissions (manager status) so they can also add Events to the Calendar themselves. The website design does not need to be super flashy. Clean, professional, and functional. A Logo Design may also be needed for this project.Programmer must be willing to fix bugs within 60 days of completion. Ideally I would want this done within 4-5 Weeks. ******Thank you for your time. This is a strict budget and please only send offers if you are a serious team with experience in similar apps.

    The app is a shopping/ecommerce app with a gaming element for a fashion brand targeted young women in the age 15-25. The app can be used by anonymous users to browse existing clothing collections shown on boards (a board consists of items placed on a rectangular canvas like photos on Instagram or +google) and every single item that appears in a collection can be added to a shopping basket in the app. The basket can be pushed to the regular web-based checkout flow at an online store and is converted to an actual order.Registered user can locate a store on a map and claim that store. Once a user has a shop the user can create own boards/collections and share them with friends on Facebook.LoginAn anonymous user can log in to the app via Facebook or via an email/password combination. Login requires a profile in the backend system. A profile can be created by entering the required information in the app.StoresRegistered users can browse a map via GPS and find virtual stores (store GPS coordinates are saved in the backend system). Stores can be claimed by a user. By claiming a store the user turns into a store owner. As a store owner the user can create own collections/boards and share them with friends on Facebook.Game element/points/earningsThe store owner receives virtual points every time she creates a collection, shares a collection or every time an item that appears on a store owners collection is sold. The backend system has an advanced and secure system for calculation points and a secure system that allow points to be converted from point to actual currency (value vouchers).StatsA store owner has access to a stat page with graphs that shows the most import numbers (followers, views etc.)Optimized and easy to useThe overall goal is to create an iOS and Android app that are extremely fast and easy to use. Every single function must be optimized to perform as good and fast as possible and the interface must be crisp, clean and very easy to use for the average user. Many of the features in the app requires internet connection (wifi or 3G) in order to communicate with the central backend system - however the app should not crash if the phone loses it’s internet connection during the use of the app.Overall minimum requirementsThe app has to work on iOS6+ on iPhone4+ phones. The Android app has to work on Android 4.0.4 (Ice Cream Sandwich) on Samsung S3+ or phones from other vendors with same computing power and same minimum screen resolution (1280x720).Every single screen in the app must be tracked by Google Analytics.Backend systemA high performance, highly secure and very flexible backend system has been built on Amazon AWS cloud services. The backend system is built according to REST API guidelines and the system is documented on a Github repository.Versioning, source code and rightsThe system belongs to the customer. This means that the customer has the rights to the concept and idea. The developer can not sell the idea or the source code to anyone else.The source code and the rights to use the source code belongs to the customer. During and after development the source code and every file included in the app must be accessible on Github in a private repository that the customer makes available.DesignThe customer delivers Photoshop files for the iOS version. It is expected that the developer contributes to the overall UI experience and makes the app modern, beautiful, fast and easy to use.

    I need to develop a coupon & event app. I also need a website developed to work in conjunction with the app. Here is how it will work:1. The app will display business info, events & coupons. App users (consumers, not businesses) should be able to set up an account manually or using Facebook. Their account will be used to review & leave comments for businesses on the app.The app will also display reviews & comments left by users for each business.2. Businesses need to be able to go to the website to set up their business profile. The website should populate the app with their info. Businesses need to be able to enter and change their business info, hours, logo, events, and coupons - all of which will be displayed on their profile on the app.3. Customers who use the app should be able to review the business (choose number of stars up to 5) and leave comments for the business. Business owners should be able to login to their account and see comments - they should also have the ability to choose whether those comments are shown to the public or not.I would like to ask if it"s possible to integrate Paypal into the website when businesses sign up so they can set up their payment to me when they set up their app profile.I hope this is clear, please let me know if you have questions.
