    We are looking for someone to help us get started on a new project. We need an example web application built for us that will have a logon page and then a main screen with a left hand navigation bar, top menu bar and main screen in the middle.We need to hook in all the different screens into the menu and navigation bar (about 20 screens will need to be setup) but we only need to have one screen to be functional and we can then complete the rest. The functional screen will have a simple data entry screen that can be added/updated and on entry will show the contains from the database. As navigation and menu options are selected the middle area will be refreshed with the new screen.We want to use Java, Spring, MVC, Hibernate, Maven, Eclipse. We need a clean implementation so that we can build the rest of the project.

  • $750 USD In Progress

    I need someone to take my basic service agreement, and then add options to fill in the blanks, so that I can quickly create contracts/agreements to send to customers. I would like to access it from an internal web server where all the files will be saved, and searchable. When I enter a contact details once, it should always stay in the system, so that I can select their name from the drop down list, and it should automatically propagate the proper areas in the agreement, like, name,address,phone, etc... I will provide you with a sample agreement with tags like "NAME" "CUSTOMER" etc... You will need to create one input form where I can input all the data quickly. There is a section that will need to be calculated as well. i.e first month, last month, and duration contract. So if the customer does a 36 month contract with me, then the app should automatically input the END date if I selected the START date. All of the files must keep a certain code, that is generated from items within the input section, for example, Location A name, Location B name, customer name, date... That should be the file name. All of the files should be searchable from the portal. Any changes or modifications to a agreement, will add the -1 or -2 to the end of the file name so that its known that this is the 2, or 3rd version of the agreement. The portal should have a calendar bases scroll section where I can monitor start and end dates of my clients. I need to have a notification system that will alert me X months, X weeks before a customer"s contract expires. I would also like to track future customer as well. Sometimes I need to wait months before I can bid on a contract again. That should be in my calendar with the details of that client, and in a different colour. I want to have notifications for all of this, sent weekly, monthly etc... There must be an option to export contact emails and or addresses so that I can print labels or what ever else is needed.For bonus options..... If you are a quickbooks expert, I would like you to integrate this with my quick books so that once make a contract, and in the portal there can be a option for "contract signed" it should automaticly send the details to quickbooks and generate the invoices, as well as build the customer into the quickbooks database.Sorry for the long ramble, but those with experiance in this, will know exactly what I need.

    We have Atlassian Jira and Confluence setup using a Atlassian Crowd server (which is in turn connected to our active directory domain).We have a number of users who should be able to access Jira and Confluence from our internal networks (there are multiple subnets) however they should not be able to access Jira and Confluence from the internet. We also have staff who should be able to access these services externally. One solution is to use a VPN however it"s not desirable, the other solution which we tried was using an apache proxy however neither app works very well over this method (unusably slow).The best solution at this point is to create a plugin for Jira and Confluence which allows us on a per-user basis to specify who can connect to Jira and from where. By default we want people to connect form anyway, however for specific users we want to say they can only access the service from specific subnets (multiple being configured). So for example if a user "ExternalTester" is setup to only allow connections from then if they connect from then they should be allowed however if they connect from a public IP such then they are denied.The authentication needs to be very light such that it doesn"t not impact on the performance of the servers.Alternatively it would be acceptable to write such a module for Atlassian Crowd (as that"s the back end authentication anyway). This would only be possible if Jira and Confluence already passed the end-users IP address through to crowd for authentication (which i"m not sure if it does or not - it may not).

    I"m looking for a creative way that will let me register deleting domains that expire every day at x time.The bigger drop catchers have their own way of registering domains before anyone else do, right as they expire - and I want to compete at some sort of level there.My initial thought would be that there might be a way to utilize a list of registrar API"s. Dynadot, namecheap, etc etc. Run them in a curl script that would enable us to hit each API every 1 seconds or the minimum time the particular API allows you to.If I had say 20 API"s that allow us to register domains and I had 10 domains that I wanted to register that expire at 2PM GMT.. Could I utilize those 20 APi"s to hit those 10 domains consistently over and over, let"s say each API only allows 1 request/sec. That would mean each domain is being checked twice per second across the APi"s *roughly*. Giving us a 500 m/s check rate.If that"s the case, we could create 5 accounts at each API registrar and have 100 API"s across 20 different domain registrars hitting each domain once per second and rotating through the list. This would mean we drop the check time down to once every 100 milliseconds.Is this a theory that would actually work consistently with what I need? I"m looking for feedback on a solution that I can get custom coded/developed.Looking for someone to create a solution for me :)

    SKILLS/TOOLS: PHP, Java, Web Security, Web Services, MySQL, POSTGRESQL, DEBIANThe project requires an individual with expert PHP and a solid grasp of designing/writing secured Web services. Please read an understand my requirements before saying "you can do it". Anyone who does not read will be ignored. Background- An open source server application running on Debian is written in Java and uses MySQL. - A web service using a PHP SLIM framework exposes data directly my the MySQL Database. - A client application written in PHP polls this web service to receive the data and stores in appropriately in a POSTGRESQL db. Mandatory Requirements1. Modify PHP SLIM service to extract a larger set of data from MySQL database. A list will be provided. 2. Create a business rule that either on server side that prevents extraction of the data unless a "flag" is on. This flag is also stored in the MySQL db.3. Ensure that the service is secured and cannot be penetrated by common security threats. 4. Document all changes and provide testing support. The mandatory requirements should be quick and I can provide remote support 24/7. Value-add requirements (Billing & Monitoring) 1. Rewrite the PHP slim service in Java.2. Allow this interface to be tokenizable and licensable. e.g. I can distribute the API and enable to API by issuing a time-limited certificate. 3. Allow remote disabling of web services if license is revoked or expired.4. Allow local and remote tracking of the number of times each web service is called. The tracking can be in the form of a text file that can be retrieved via SSH. Must track token ID, date of issue, date of expiry, number of times web service has been called, number of times web service is successful / fails. Write access by only authorized users. 5. Create an auto-deployment package for the web service in a Debian environment. 6. Ensure that the service is secured and cannot be penetrated by common security threats. 7. Document all changes and provide testing support. I would like to get two quotes. One for the mandatory requirements and another for the value-add. I expect the effort to be small for the mandatory. I prefer expert level skills who are highly available and can complete the job in a matter of days. No shops who have developers that work around the clock. Terrible experiences with you guys!

    We are looking to get a mobile application developed for both the iPhone and the Android OS. We have a well thought out application that will require creating user profiles, chats between users, group chats for multiple users, geolocation, and a matching system between groups. This application will also require some proper database creation and management to handle the back end for users and other stored data. I apologize for not explaining the application in full here, but will require the developer to sign an NDA before we can disclose all the details. We are looking for a single developer who can do both iOS and Android, as we don"t want to use one developer for each OS and complicate everything.We have a large budget depending on what all you can offer us, and would like to see the full mobile application completed within 120 days. Thank you for your interest.
