    There are a few components to this. I'd like it written in Swift, as I'll be making modifications to it down the road. 1. Create a data model based on two different spreadsheets which need to be imported. The spreadsheets are in Excel XLS format, so this program needs to be able to read and parse XLS files. One XLS defines different wines and their attributes, basically a definition... region, type, vintage, rating, cost, value, tasting notes, range of years where the wine is best, etc. All are columns in the XLS, so it's very straightforward. The second XLS is a bottle list... a list of how many of each type of wine there are. Fields are things like bottle size, cost, date acquired, location in the cellar, straightforward as the columns are well-defined. 2. Once the ...

    I'm looking for a software developer to create a desktop projection mapping application for Windows and Mac.

The closest precedent for the software concept is MapMap (), which allows users to pull around corner handles in order to warp and manipulate a projector's output. MadMapper () is another good point of reference. Upon opening the software, the user would be met with a prompt to confirm that their projector is correctly set up as an external extended display, with some links to instructional videos on how to do this. Then, the user would be presented with a canvas automatically sized to the resolution of the connected external display, with a heads-up d...
