    With many years of experience in various IT companies I am ready to propose following services on "as-needed" basis (sorry, no fulltime employment): 1) Complex engineering tasks related to server-side linux scripts, such as troubleshooting, code review, implementation/adjustment of complicated logic. Supported languages: python, perl, ruby, bash, lua. Haskell, erlang, clojure are possible as well. They are subject of special (lower) rates, due to lack of practical experience (versus solid theoretical understanding and general interest). 2) Advisory in organisational questions for small & medium teams. Workflows, infrastructure, staffing, project management (including risks management, resources management, planning etc). 3) High-level design of the service-oriented architectures, data processing (ETL) flows, devops solutions in linux/cloud environments. 4) Any kind of engineering/architectural work related to functional programming, evented programming, nosql. 5) Advisory/troubleshooting on nginx and hadoop, with basic practical experience in high-load web services and massive data processing. Rates are flexible, depending on particular case. Is this expertise exactly fitting your problem? If so, just message me. Not sure? Message me anyway so we will find an answer together.  less

    Guy with big shoes who spent a lot of time in rushing into the technology stacks. He mostly get his hands dirty with high engineering where we need to start with atomicity, enhancement, scalability and distributed architectures. He knows what we have to do when the implementation is not just about the tech talk. Wait, did you asked write me to write the for loop? Well, there are a lot of other challenges as well when it comes to the choice of stack, selection of write platform and ability to end up with the exact matters! He has experience of working with different frameworks, languages & platforms. Usually, you'll find his hands dirty into something really reliable and that is making out high-end engineering. He's familiar with the solutions & principles required to write own framework as he has written couple of MVC, HMVC & boilerplate frameworks in PHP & Node.js. In back days, he was working with PHP and spent all of his big part in that. But now you'll always find him working on Node.js with some top class stacks to make robust & scalable products. Hamza is *nix (OSX / Linux) enthusiast so don't tell about benefits of using #windows. The guy with entrepreneurial spirit (no, I'm not that fake VISIONARY ENTREPRENEUR) and is already co-founding few startup companies. - Zend- Kohana- Slim- Drupal & custom written MVC frameworks. - Node- express- compound- restify - Android SDK- Play! - MySQL- Oracle9i- MongoDB- OrientDB- Redis- Cassandra - Hadoop- Storm- Mahout- Stanbol- Tika - ElasticSearch - Backbone- Ember- React- Angular - Git- SVN - EC2- S3- DynamoDB- RDS- Redshift- SQS (Amazon) - RabbitMQ- Gearman- Kafka- ZeroMQ- PubNub  less

I have applied these skills in both academic and industrial situations. I have statistical analysis experience with R, MATLAB, Excel, and SPSS. I am fluent in C/C++, Java, Perl, and Python.
