We're looking for a developer to create a software that will create an adhoc connection from a Raspberry Pi to a Windows 10, ideally Surface Pro tablet, and keep trying to connect until connection is made. And give a fixed IP. So that we can do local IP calls from the tablet to the Pi. Also want it to work between 2 Windows machines, so can connect 2 Windows machines via adhoc with a fixed IP. We have a web / desktop application, that sends local IP calls to another PC, like http://192.168.0.3/?query=1234 and we need a closed network call to another PC. If the Computers switch off, when they are turned on, they should automatically reconnect, and so if any new local URL calls are made the connection will always be on automatically. So need software script developed to get this done, and tested so that it is robust, and will never fail!

We are launching a project to build an automated terminal scripting system with comprehensive workflow building, management and debugging. We are working with enterprise networking hardware (Cisco routers, switches, etc.) and are looking to automate manual management processes over telnet. We’re looking for someone who can build a system that will manage the communication with the hardware, including determining hardware and firmware details on the fly and performing actions and updates as needed, as well as alerts to users. This system will be used and managed by network administrators fluent in the hardware. A core element of the end product is that it needs to provide service access to separate terminal emulators and data warehousing. We love technology and solving problems with the right tools for the job. We do a lot of web-based work on the LAMP stack but have used node.js, bash scripting, PowerShell scripting and are looking into Python and Go where the situation fits. We’re passionate about doing the right thing, which for you means a simple maintainable code architecture, tight adherence to proper coding standards and a willingness to think ahead and prepare for future requirements when we can see where we want to go. You’ll be working with on staff development for project design and management. Qualified respondents will receive a detailed project brief. Fluent English is a must as well as some (but not all) availability between the hours of 9-6 EST. Please advise if you represent a development group or firm, or if you are an independent freelancer.

Make a simple OS X Application (Mac OS X 10.10+) from bash script (shell script) that we already have. We have a bash script. Scripts are running sequence of commands (about 1000 lines of code) like downloading drivers, unpacking, installing them. We would like to make it user friendly and make a simple application for Mac OS X. Minimum user interface. In fact it is necessary that a user does not see the terminal window, but inside the application can work the same way as does the script. See script in attach and detailed task. IMPORTANT: Please review the script and make your price quote and add cover letter.
