    Linux sysadmin, cloud deployments specialist

    Czech Republic - Last active: 1 day ago - Tests: 9 - Portfolio: 1

    I would like to offer you my deep knowledge of servers hardware and software, which allows me to fine-tune servers according to their roles, and my ability to anticipate and solve problems in shortest time possible. No Windows please, Unices only, Linux preferrable. Lately my main point of interest has shifted to deploying and maintaining web projects in cloud environments. I am developing monitoring / management tool ( http://m-script.org ) and supporting existing installations, but I am very well familiar with all well known alternatives from both monitoring and cloud management side, so no problem to implement any of them. The point is, I know very well how it works. And how it doesn't, too :) I am interested in any system administration work, especially in cloud environments. The more challenging you setup is going to be, the better. Automated scalability, cross-clouds deployments, combination of traditional and dynamically scalable resources, DNS/Geo balancing - everything is possible, just let me know your needs.

I have developed systems using Neural Networks, Markov chains, Support Vector Machines in various applications: OCR, image processing, data analysis, text indexing and retrieval. I am also proficient in 3D image visualization using common off the shelf libraries and methodologies, either low or high level, like OpenGL, DirectX, VTK, Java3D. I understand and use common ray tracing programs. I understand image processing topics like segmentation, thresholding, classification. I have worked in the past in a 3d Face recognition European project. I know the OpenCV library quite well. In the field of "general programming" I have a good understanding of Databases, multi threaded applications, sockets, pipes, encryption (symmetric and asymmetric), compiler design, operating systems, low level data structure in memory and on disk, data integrity. I consider myself an expert in data structures and algorithms: trees, queues, lists, b-trees, hash tables; I use standard libraries like STL, Boost, Java generics. I have a good knowledge of SQL and data normalization however I have also used custom No-SQL databases like Datadraw, MapDB, Tokyo Cabinet, Zope. I know all the basic algorithms and templates used in every day coding; regarding data integrity and security. Compression (lossy and lossless), symmetric and asymmetric encryption, public certificates, I have worked with OpenSSL programming, encrypted web services, packet sniffers. I am proficient in all the common every day languages with an emphasis on C++ and Perl. But I can use: Java, Python, Visual Basic, C#, PLSQL, Delphi. I know all the Object Oriented Programming concepts and design patterns and I use them if the need arises, but I am also able to write object-free programs in C or functional languages (like Haskell or Scheme). I know modern version control systems like git and mercurial, even if I can use also older ones like Subversion or CVS. I know Windows programming and API quite well. I have used WPF and WCF to create desktop applications in Windows and web services. I have used Linux and Gui toolkits like Qt which are platform independent. I know XML, XSL, I have used several parsers like the MsXML or Xpath. I know how to validate a XML with a schema. I have worked with a team that handled thousands of XML documents relating to air crashes in a SQL server database. I am able to talk and write in English with fluency. If anything is not listed here either I have forgotten to list it or I can probably learn it quite fast, so don't hesitate in asking!

    Back-end and front-end dev and photographer

    Ukraine - Last active: 1 day ago - Tests: 2 - Portfolio: 1

    I specialize on Ruby on Rails and front-end development. In spite of the fact I have got a degree in International Journalism and Translation, I worked as QA and IT Sales for total of 3 years (from 2008) and then moved to web development from Jan, 2012. I have performed both back-end tasks (from basic CRUD to making simple APIs or server scripts) and front-end (building static websites from scratch or developing views with twitter-bootstrap). I believe the experience is formed with the quality of the projects, you have delivered, and not with the years of sitting in front of the laptop. Specialties: ruby 1.9.2+, Ruby on Rails 3.0+, linux and MacOS X environment, unix-shell, Git, SQL (SQLite, MySQL, PostrgeSQL), HTML, Haml, CSS, Sass, Less, twitter-bootstrap, javascript, jQuery Here is link to my github profile: https://github.com/amseledka I do photographs and various design tasks in my spare time, as well as help my friends with Russian-Ukrainian-English translations.

    Python/Django developer

    Russia - Last active: 3 days ago - Tests: 18 - Portfolio: 11

    I am a Python developer. I can use Python in almost any task and context. And I love using Python, although I know other languages if you need something occasionally. Just contact me if you need a web developer without ophidiophobia :) I have more than four years of web-programming experience with Django framework (on both large and small projects, plus some experience with Flask and other frameworks) and more than six years of professional Python coding. And I want to continue it: participate in web-development with Django or otherwise, developing desktop applications, writing various helpers and integration scripts and so on. Working on different projects, I've got a vast experience with different version systems (strongly prefer Git, but can use Mercurial and Subversion if needed) and common workflow techniques, like Gitflow. Collaboration services and task trackers I worked with are too numerous to mention. Additionally, I have some experience with other technologies and experience of Linux system administration and know the best practices for system design, performance and search engine optimization, web application deployment, setting up hosting servers, continuous integration, monitoring. And I can learn new things, of course. Technologies I can use for front-ends (when I have to do them): - HTML5, - CSS3, - Javascript, - jQuery, - Twitter Bootstrap. For back-ends I can build both usual MVC-style applications and REST APIs. I have experience with a lot of Django reusable apps and know what to use for which task. Just to name a few I'm familiar with: - Tastypie, - Django REST Framework, - Haystack, - Celery, - Storages, - South (and native migrations in new Django). On top of it, I know a lot about various useful SaaSes, like: - AWS (EC2, RDS, S3/CloudFront) - DigitalOcean, - Twilio, - Stripe. I tried to keep those lists short and clear, so if you need some particular technology I haven't listed feel free ask me about it; chances are that I worked with it or at least know something about it. (And please never mind the "agency contractor" thing — I am my own staffing manager in that agency and I don't work for anyone else. The agency was formed only for payment consolidation with a couple of friends.)
