We are looking for a big data expert with experience in hadoop, spark, presto, hive, mysql. You should be super experienced in setting up the hadoop architecture on any cloud server. On the high level, this is what the application needs to be doing. 1) We need to fetch a lot of data from several different apis which have different formats of responses and different data representations. 2) We need to clean this data and put them into a sql database. 3) This data will then need to be retrieved by an application that requires a data source which will be the datatable to reference - this is the front end that will pull the data from our database: http://www.tableau.com/ 4) Fetching data from these data endpoints / apis needs to be done in the most efficient manner possible and also retrieving data from our database needs to be efficient. We are looking for someone highly experienced in: - Big data and has experience in working with large / huge data sets of millions...

I'm looking for an experienced data scientist who has had some experience working on process optimisation (engineering related) problems. My data set is from a power plant desulphurisation process which has approx. 100,000 observations and 30 variables. Using this data set, I would like to model the number pumps used in the process with respect to the other variables. Then based on the derived model, you would need to find the optimal solution at which the number of pumps used is minimised subject to a few inequality constraints. This is an interesting problem and I'm confident that whoever takes on this challenge will find it rewarding! I would need the code written in R. Also, practical experience in Machine Learning and Nonlinear Programming would be required. If selected for an interview, further details about the project/expectation will be provided. I look forward to receiving your application.

Hi, The job is to create a R script that does the following. 1. Takes a number as argument. This is the number of days to look back. 2. Read in csv files in a directory. The files are named like this trades.20150519.csv The date is in the filename and the date to look back is determined by the argument. 3. Calculate profit and loss for the strategies mentioned in the CSV file and send it as email. Also list the trades for the strategies. Details: the file looks like the one attached. the strategy name is in the order_ref for the entry.

Scope of work: I am seeking a financially literate (derivatives trading, Black-Scholes, option greeks, binomial models) programmer. Phase 1 will be to create a simple random walk Monte Carlo (or geometric brownian motion) simulating the price of a stock with the volatility as a variable that dictates how much percentage the price can move from time1 to time2, following a log-normal distribution. Simple enough since I created a rudimentary model in google documents that does just that. The more complex part is to design a trade strategy that is based on a modified martingale which will go long/short. I have several google docs available that go into the mechanics of the strategy. Phase 2 will implement the same strategy (should it prove profitable) using theoretical options pricing models to achieve the same results as phase 1 utilizing call/put verticals and condors. Phase 3 will be a backtest of the strategy on real data.
