Looking for a NoSQL/BigData developer to fulfil a simple API for a web app which uses social data. The design needs to be mapped to a NoSQL/Big-Data db. It will operate in real-time, so it needs to be programmed in a highly responsive/low latency manner, and would need to run on a scalable NoSQL datastore, such as HBase or Cassandra (preferably HBase). The API can be fulfilled in c/c++/python/ruby/java; our preference is java. This project should take roughly 1 month or less. It can be done as a one-off job, or as a trial project leading to potential full or part-time employment. Based on performance, minimum payment for this project can increase significantly. Our company works in machine learning, robotics, data science, natural language processing, as well as crunching numbers for the financial industry. We offer flexible hours and the opportunity to work from home. --- An alternative path to this job is that we would look to hire (long-term) someone without particular programming/development experience in the above listed skills and areas. However, this person would have a keen interest and solid experience in science, mathematics, engineering, or other relevant technical aptitude; someone wishing to learn and engage in big data/data science jobs. The ideal candidate would have an interest in puzzles, solving how things work, and experience in using the scientific method.

So, I feel I am the right candidate for this work because of having major experience in big data and hadoop HDFS and developing recommendation on top of hadoop. Here this project has multiple things UI and backend(big data store) and there has to be a seamless integration between these two also I have few question in mind if you have time we can discuss on those. Bid can be negotiable after discussion. One more thing money is not important for me thing that matter s for me is satisfaction of client and I mean it.

I do data mining / machine learning on business data - sales, marketing, customer behavior on eCommerce sites, etc. I started working with data in 2000 at a major mobile telecom here in Bulgaria, I left in 2007 to continue as a freelancer and last year I established a small consulting company. Since 2007 I've been using mostly various components of the hadoop ecosystem (including HBase), that I usually prefer because they have better integration and allow for greater 'openness' of data. In my experience when researching data it makes sense to be open to all sorts of 'angles' or 'view-points' on the data. I've also used Cassandra and other non-hadoop components. And I do develop API's to export services to web front-ends (in java). And of course, I'm always looking to find more opportunities to discover knowledge, truth and generally - what hidden factors determine the reality we observe. Can't write much in here, the message is limited in size, but if you think I might contribute to your project I'd be more than happy to answer your questions. Thank you! Cheers, Andrey P.S. I'm required to fill-in a milestone. At this point I'll only put 'to-be-defined' as I'm not really able to offer any plans...

From the face of it, the job requires a Java Developer to write the connector a NoSQL guy to model the database and an ETL guy (?) to cleanse and make data in a suitable format specific to the DB model. I can provide you an end to end solution. Vineeth Modon

My team is really interested in this project as it is exactly within our scope of expertise: We are web/ app design & development experts. Please kindly visit our website phamtech to learn more about us and our works similar to this type of projects. Working with a team who has both in-house DESIGNERS and PROGRAMMERS means that you can take advantage of both: Our designers could help revise the design even in coding process, which is a GREAT benefit for any ongoing project. + We plan and build. We don't use prebuilt templates which produce conflicting codes and bugs and hurt the system in the long term. + Our team is 100% in-house. We don't outsource projects elsewhere. So you pay for the real service - not marketing fee. In short, if you need an experienced team who offers *real English* communication, beautiful design & optimized code, premium after-service, in time and to budget, then we are the choice. If you need something based on solely ONE of the above criteria, then we're still happy if you decide to give another freelancer a chance. Just bookmark our website and come back in case the selected freelancer can't meet your demands. * Even if you don't go with us, avoid fast food services. Chances are they omit the software planning & testing phases for the sake of reducing time & cost, which produces unsustainable codes behind and creates more distrust in this market!

I graduated from Carnegie Mellon University with a master degree. I have lots of industry experience in big data area. I worked at IBM, Twitter before. I know how to use hadoop 1.0 or 2.0 to process data. And I also use pig to analyze data. I use oozie to manage data pipeline. I have hands-on experience to use Amazon EMR. I also have lot of experience to use avro both on hadoop and pig. I used cascading and scalding before in case that you don’t use oozie. I think I will be a good fit for this role :)

I am currently working as a BigData Engineer at a media company in the Netherlands. I have already built several APIs for them using Python+Flask with various SQL and NoSQL backends. In this position, I am also managing a Cloudera Hadoop cluster and developing real-time processing systems using Storm. With HBase I also worked closely: my Master's project was about efficiently storing loading Semantic Web data in HBase; in addition I have a CCSHB (HBase certification from Cloudera). As a result I have a good understanding of HBase internals and how the choice of data model affects the scalability and performance of the system.
