We have the most powerful compute optimized virtual machine instance that Amazon Web Services offers (c3.8xlarge). This includes 32 virtual CPUs, 10Tb of SDD storage, and 60Gb of memory. It is running Ubuntu Server. You will be granted access to AWS in order perform the work. We need to do four main things: [1] Develop a script to import the data from the files into a master table [2] Derive additional fields using existing fields contained in the master table and add those new fields...

We have about 30 different formulas that are all querying a single "revenue transactions" table inside our database. We need your help to convert and implement each of these formulas into SQL syntax so that we may run it against our dataset and get the output for each of them. The formulas generally are related to computing revenue, profitability, business break even, profitability, net revenue per period, and revenue projections incorporating existing customer attrition rates. We can run this against our MySQL and/or other columnar RDBMS with stats functions (except Oracle)

We have nearly 1.5 million products on our database, 9000 brands and 150 suppliers. The task is to create a solution which can help to actively identify products to users. Currently each user stores their desired products in a wish list but trying to find the desired product can be quite difficult. We want suggest relevant products to individuals. This can be based on any criteria. This can be up to you. Currently we know the age, gender, location and relationship status of individuals. We thought this could be managed by weighting Supplier, Categories, Brands and Products. Initially we could ask users questions to identify what criteria they may fall in to. This is just idea not the solution. We are not asking for a developer to develop the solution, just a designer to design it. Please submit your proposals and proof of experience.

I need some help building an online platform for querying geographical data. I would like to create a webpage with an interactive map on top (from google maps or open street) and below a blank space where various plots will be displayed according to the position queried by the user from the map. I deal with wind speed and direction data, so I need the tool to be able to fit and display a weibull distribution, a rose plot (for wind direction) and some other simpler plots. I also need the tool to be able to take the data from the geographical location, do some data processing and display the results. The crucial thing is that I need the whole thing to be very well explained with commenting so that I can replicate and maybe add material to the page once the final product is in my hands. If you need any other information please contact me. Thanks.

This task calls for a Computer Programmer who could input certain mathematical "If-Then" "Rules" into an algorithmic code/program GUI which could be used as a template offline "Calculator" (Preferably to be used on a Computer as opposed to an "App" mostly for security reasons). This created "Calculator" (I guess it would be a program) is to be used towards algorithmic filtering of user-inputted "Live sports statistics." The algorithms rules are to be used to determine eligibility of what decision should be made by the user in regards to Sports Wagering. I don't have much computer programming knowledge myself, and I don't know which Language would be best suited to turn my "Rules/Laws" into a coded program to use. So any advice/consultation or provided examples, could be useful in deciding which language my idea should be coded in. My idea is a system of rules meant to be put towards an algorithmic gaming formula, ...
