We are in the process of launching our web app in a few weeks and need a dashboard that helps us track already defined KPIs and user activity within our program at a detailed level. Examples of KPIs for our app includes the user’s first encounter with the program via an ad, initial engagement with the program, completion of various milestones within the program, submission of feedback and more. We have a specific and detailed set of business intelligence requirements and we need a talented and amazing developer with a strong database design and development background to translate our requirements into a logical architecture and dashboard. In terms of the DB, you would be connecting directly with the PostGreSQL database of our app. Whatever BI tool we use must be able to integrate through api to Facebook's ad manager, to pull in performance and parameter data for campaigns, ad sets, and ads. Ideally, the amazing person we select and selects us will work with us closely (remotely) over the next few weeks.

We have developed a system to capture certain images. We need a Machine Learning and Image Analysis expert to develop a system to be able to determine if a certain event is taking place in these images. We are able to supply thousands of photos analysed and pre sorted into negative or positive matches. If you have a track record of implementing complex machine learning and image analysis systems then please get in contact so more details can be provided. Thankyou

We are building a platform that is heavily data driven, working with select clients globally. This is a long term project which requires full time development. The machine learning system will need to be built from scratch and will need to capture specific information at certain data points. This will be the "go to" analytics system of the platform and will record all data across the platform, so it will need to be very, very robust. The system will need to understand and analyse user behaviour, building a profile of each user, and give the business the ability to visualise the data in an easy to digest manner to those less technical. Currently the business requirements are being completed. The designs and technical requirements are being finalised and we are looking to kick off development approximately at the beginning to December. I am keen to gain your feedback as to whether you would be interested in working on such a project and would be happy to discuss further with you over skype or phone. Please note that the budget is negotiable (up and down) dependent on your skill set. Thanks, Samuel

I need to quickly create a demo - to simulate the plotting of 1M records (Excel CSV file) that are time stamped to make it appear as though the data is being plotted in real time. For Example - the simulation should be similar to charting stock prices in real-time as if you are watching a stock (say IBM) price being plotted on a graph in real time - every 1 sec, 5 sec, 30 sec, 1 min , 5 minute etc... - then i want to be able to speed up or slow down the time using a slider or by entering the speed . for example if i enter 3x, the data is plotted in the graph 3x faster than normal time - (like an audio or video that can be sped up and slowed down) and I need to plot this graph on to this dashboard

What we need is someone who is not only skilled in analyzing data, but knows how to apply it strategically to various digital marketing channels in a holistic fashion. All of the difficult work of creating a survey, obtaining statistically significant results, cleaning, visualizing the data, etc has been done. We just need someone who can tell us how to use the data to meet our goals. This will take some back and forth with me, and creating more visualizations within Qualtrics. It might also mean comparing the results with our AdWords data. I need someone who can really listen to my rather unique concerns and help us get what we are intuitively after. Background: I manage the strategy for an outreach website aimed at creating more people who believe that land value tax is a desirable and important policy for ending poverty and saving the environment. I need someone to first compare our existing survey results, preferably using Qualtrics, to the academic theories of Dan Kahan, a professor at Yale. The theory is called Cultural Cognition, which puts respondents into 4 buckets. This theory is useful because of its power to predict how people will answer many questions about society, beyond the 5 questions in the survey. We already have broken the responses into these 4 buckets the best we can, but I can't help but feel that we need to dig deeper. We currently receive $40K in free advertising from Google AdWords for being a non-profit. We also have a newsletter. We have data from all of these activities. We need a 2nd opinion on our overall marketing strategy. We are juggling two goals, to identify as large of a chunk of society as possible who is likely to be interested in our ideas and to better market to them. Our other goal is to influence people in the San Francisco Bay Area who will attend our events and perhaps donate to our cause in a variety of ways. Please read and comment on this document:
