    Hi there,I am referring to a project you have done for someone else which is programming a bot for the purpose of buying art prints. I therefore take the liberty to repost more or less what your other customer already had posted:I am looking to create a bot that will automatically add art prints into concurrent shopping carts and to pay via paypal. It is critical this bot is extremely fast. 1-5 seconds MAX to complete all purchases. Also it must work on my MacBook Pro. Furthermore it must be easy to handle as I am not not really good when it comes to IT stuff.Basically these store release different posters at a set time . Im looking to...on my Macbook Pro1. add art prints to concurrent carts (6+ max), have to be handled separately as there are rules that only 1 posters can be purchased at a time --> how does that work in practice? Did this guy have several paypal accounts in order the seller did not note that he is buying several prints? I would be already happy if it worked for 1 cart. But it should be possible to install on several compurters2. go to check out, click on paypal link3. select 1 of 6 ship to addresses on the paypal checkout page4. confirm order back on e-commerce sitesI am looking forward to hearing back from you on this.Cheers,Casi

    Iphone GPS sender required for employee monitoring.

  • $3052 USD 3 days ago

    Freelancers Located in China ONLY please.We currently have an Android app and website system to track the flow and speed of products in our factory. We want to remake our entire system to allow for more expansion and better user interaction.What we currently have and need redone:Android app that allows users to login. Each user is designated a "Location" in the factory, after login the user is able to scan QR codes. The app scans QR codes and updates the database of the time it passed each location. There are 10 total locations, 7 of them only record the time it was scanned. 1 (Repairs) only records how many times it was scanned, because it is potentially scanned multiple times at this location. Another location (QC) also records QC issues the item had, example, transit damage, paint chip, assembled wrong etc. The last location (Container) records everything scanned that day and puts in into a separate file on the website called "(Date) Container Loading List" The website creates QR codes for each line of an excel file we upload. We upload a new excel file for each order we get. When the items are scanned the database then creates 4 different reports:1. Daily scan report: reports on how many cubic meters and quantity have been scanned in each location.2. Weekly Scan Report: Reports the average amount of time the items took between each location. 3. Container scan report displays where each container is located, in %.4. The QC location also records issues with the item and creates a report for the issues over a certain time period and displays it in a graph.What we want in addition to the above:We want to create an extensive database for all our models that includes bill of materials and the time it takes to be manufactured. The time it takes to be manufactured will be derived from the last 2 times we made the item. It will average the last 2 times we made it and give us the time it takes in each factory department. We want to be able to search and sort the bill of materials to see how many of each component we need from Date 1 to Date 2. Or in Containers 1-10 For example.For certain locations we want a prompt on the app to force the user to take a picture of the item or to complete a checklist. We want this customized so we can decide which locations, and what check list to complete. It may also be decided not just on the location but also on the model of item. For example, all ABC-001 need to complete a ABC-001 check list at X, Y, and Z locations.Add another user called "Management" but this is not a location. When a QR code is scanned it displays the items information as well as the time it was in each department. So it is basically the same report as the weekly report but it is only for this one item. This location doesn"t record anything, its for management to be able to walk through the factory and do spot checks to see how long items are taking in each department. But it does have the option to Flag the item and take a picture of it.Also add a user that can access the site but only view it, and admin can select what can be seen. No data can be changed by this user.We currently use excel and macros to create slips to attach to each item, but we want to site to create these along with the BOMs (Bill of materials) and component slips (these have a picture and dimensions of each component). Attached is an example of them.For the site, we want 2 versions, an English version, and a Chinese version. Both identical in function and data. You are welcome to build off what we currently have or start from scratch. We want it to be very functional, customizable, easy to use, and good looking. I will happily give more information, answer any questions and show you the current site so you can better understand our needs.

    Our team has developed an exciting new game based on Cocos2d-x. We have already optimized the game for iOS (iPad and iPhone). Now we want to optimize our game for Android (for BOTH Google Play and Amazon). If you do a great job you will get further projects from us in the future via Freelancer.com.Your job will be to add some device specific funtions and to check that everything works like a charm. For your interest: We used cocos2d-x version cocos2d-2.0-rc2-x-2.0.1Alright, this is a list of features that we need:- You will need a MAC. Why? Well, we already finished the development of the iOS version. Your first task will be to play the game for about 10 - 15 minutes to get a feeling for the game play.- Support of both Android stores "Google Play" and "Amazon"- You will get a key/certificate and passwords from us to sign the app with- The game should run on Android devices right away. But as we don"t like Eclipse and focus our strength on iOS, it will be your job to find out if everything works correctly on Android devices, too.- You need to provide us a file that we can simply upload to our Android device for testing purposes.- Our game supports In-App Purchases. We use Soomla and already finished the iOS part (which is most of the work). You should have experience with Soomla and you need to create In-App Purchases for Google Play and Amazon (You will get login details from us).- If a "Restore Purchases" button is necessary for Android, you need to add this functionality. Otherwise we can simply hide this button for Android devices.- We need to provide a "share" possibility for Android devices: email, sms, whatsapp (if possible at all), via website url call (for Facebook and Twitter) and via copy to clipboard.- Rating function: Forward to the Google Play or the Amazon store for Android devices.- I18N: We have a list of 22 different language names (e.g. "chinese-simplified"). You need to create a function that checks the language of the device and if it is one of our supported languages it should return the name of the language from our list instead of default "english". This function will be called at several places of our code. But all the other I18N code is already finished and works fine.- check loading screen and game icons (so that it looks good with correct proportions)- check image proportions for different Android devices (it should work fine as we have developed the code in a special way that supports all resolutions)- check if all Audio files are being preloaded correctly- check if all Audio files are being played when trying to play them for the first time on Android devices- for Android we have developed a "No Audio" button. Check if it works.- do NOT change any basics of the game like "difficulty" or basic functions that don"t relate to the Android specific part- we need this project finished ASAP. For this reason you should not have another project during this time. You should focus on our project until it is finished.Alright, this sounds like much work but actually you could finish all this in about 2-3 days of work. We have posted this project twice so that you have the choice between "hourly rate" and "fixed price".Please apply ONLY if you are super experienced! You should be one of the best cocos2d-x and Android developers! Do NOT apply if you don"t have much experience with cocos2d-x yet (sometimes people ask: No, it is different to cocos2d).Furthermore please start your message with the word "Cocos2d-x" so that we know that you read our complete description of this project.And finally: Have fun! :)

    We need to write an app where people can download it then take a picture of a product they want to display for sale. The app will use GPS technology to know exactly where the product is being photographed. People can then view items for sale that is closest to them. So somebody should be able to download the app and turn it on. Once turned on it will use GPS to know exactly where person is and than show them stuff that is for sale from people in the area. It must work like Tinder app in that it shows the products that are closest first and then people can swipe to the next product that is second closest and third and so on.People should also be able to SEARCH for whatever product they want and it should show the distance (in MIles) to the location of that item for sale.App should allow people to ENTER a category for item they are about to take a picture of and then an area for the name of the product and a space for the price.

    I"ve already started working on this, but need someone to finish it:I need an iPhone application that allows a user to post a video from a user"s camera roll to Vine. So basically: 1. Show collection view of user"s videos. (I"ve already done this)2. Upon user selecting a video, allow user to "scale (shrink or enlarge and crop" the video (square shaped), as well as adjusting the video to be 6 seconds or less.3. At this point, if the user hasn"t logged into Vine yet, allow them to log in. This is either through username and password, or with Sign In with Twitter.4. The user can then type the message with hashtags (a thumbnail of the video next to the text), select the Vine category, and upload the GIF to Vine.Other things:- The preview of the video during the Scale and Crop screen should feel just like a Vine video.- Any music/sound included in video must also be added to the Vine video.- Do NOT worry about the design of the app beyond what I"ve mentioned. I can design the app myself.- I need someone who understands ENGLISH very well. You will be adopting the project I"ve already started which was written with English named functions in Obj C.

    Brief Description:We are looking for a fairly simply app which will work as a check list for when our workers/staff finish a job (typically around the construction industry). The app will send an email back to our office with a range of items which have been complete after an installer simply ticks a box, inside the app, and uploads a photo (photo is not necessary, but nice to have if possible).Reason for app:We found some jobs are not completed with the adequate information for what we need to finish the job. currently, we have a paper \"sign-off\" form, but this is too hard to manage as not all the time is the document sent back to our office. I have attached two documents. One document is the paper check list we currently use. Another document is a rough wire frame of how we hope the app will work. Given this is our first app, we are looking for your expertise in all the areas. We are hoping for open ended communication with transparency in every step along the way. We also have many questions on the smaller details which we feel are important to us. If the project is successful, we will no doubt be continuing our venture with our new concepts for app, mobile communications etc.
