Encountered some minor scheduling setbacks in the early stages of development, but bounced back very well and delivered work that was well above expectations. Well worth the wait!

Great for back and front end development, very skilled, and comes with high amounts of expertise. Just be sure to set in place clear milestones to ensure the project sticks to schedule! Comes highly recommended. Hire this team and you will not be disappointed. They do wonderful work! Thanks Chenjing2579!

    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 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.

    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.

    This could be either a mobile site or a mobile app (iPhone at first) The idea is to use the Tinder style functionality / user experience. But to link this to your photos on your Phone - so you can easily keep or get rid of them. If pull left - get rid of the photo. (Place in a recycle bin - feature added.)If pull right - keep on the phone. If double tap - send up to Drop Box. The only extra feature we might need later on is a recycle bin area. So at the end of the session - the person can say they definitely want to get rid of those photos. And then a counter for how many photos you have placed into the recycle bin. We are looking for a developer who can use the code bought below. any other Tinder like app. We will buy the code for you to use and need the extra functions coded for.

    I am looking for a very experienced Freelancer to make me a Add to Cart Service bot. 
How this works: 
At 8am or 10am EST time on a release day, will tweet out a link to buy a shoe and then this bot must automatically click on the link which directly takes you to shoe, choose your size, add to cart by skipping captcha. Also this needs a checkout option but not automatically actually checking out, needs to be an added option. There are other bot programs out there that automatically do this but I need a program that is more advanced. How the Add to Cart Service NEEDS to work:

 What this system will do is when Nike tweets the link, in the back-end this Bot must open the link and add the desired size to each customers cart. 

I will need to have a page where I can insert Accounts, The Size it needs to get, and the buyers Phone Number and email address. 
What the bot will do is it will login to the Account and when the link gets tweeted, You (the freelancer) must make a method where the Bot can login to Accounts (around 100) and add different sizes to cart and then log out once the shoe is placed into the cart. This has to be able to login to MULTIPLE Accounts and also must be able to choose any size I need it to and that I will NEED to be able to do in a section (like an admin page) that only I can access where I can put in orders. 

This admin page also MUST tell me if the bot was successful at adding the shoe to the cart and MUST tell me if it was unsuccessful (for each order). Then here is the important part:

 Now in REAL TIME it MUST TEXT MESSAGE (SMS) the person who placed the order (which I put phone number and email in admin page) saying if they got it in their cart and to go log in to their Nike account. 

The most important part of this is SPEED. This bot needs to fully bypass the human verification system on so it automatically adds the shoe to cart in seconds. 

Freelancer must understand that I will need support if there is a problem, etc. If this Job goes good, there will be a lot more jobs between the freelancer and I like updates every once in a while when needed or when I just want a new feature (Work for another site, etc). 

*******VERY IMPORTANT ********
 this also needs to be compatible with mac. Updates have to be included in the bid will need updates whenever nike makes a change to the way the launch products or just change website. Will also need some updates when I would like new feature. It needs to be a file that I can install on multiple computers, but it needs to be locked on certain computers so that I would be the only person to send it to a friend and they wouldn&quot;t be able to give it away. (Maybe a verification through twitter where I can activate certain accounts to use the bot and those accounts can only be used for 1 bot) I also need to be able to make copies of the bot and be able to limit number of accounts that someone can put in bot.

 If you could do all this, that would be great. Please get back to me soon. 

 Thanks Brief Description:· Needs to fully bypass captcha· Needs to be faster than any human or other bots· Admin account where I can add keywords and accounts· Verification so only 1 person can use a bot and CANNOT give it away – I need to be only person able to give away and limit accounts able to be used on bots when I lend to friend or something· Snipes twitter link via keywords· Multi-threaded· Over the air updates when needed (Nike changes site or just have something to tweak· Mac compatible· Send out notification to Nike accounts I bot saying if ATC was successful or not in real time (immediately after success or failure)

We are seeking someone who would be willing to work pro-bono with a promise of full payment of work once the app starts making a profit.This is a utility app, the nature of which does not currently exist in the App Store, so it is unique in its value and should be reasonably simple to build as there is no social or messaging elements to it and little if no animation required. If you feel this is something you would be willing to be a part of...drop us a line!Regards,TMac
