Sorry! :)

I am a wizard. Seriously. I use rare combination of talent, skills and hard earned knowledge and experience to solve others' unsolvable problems. Wonders and miracles done immediately, impossible stuff with minor delay. My most interesting project come from oDesk. Such cases were, for example, helping Panama based company OSOP with systems they use to predict (and provide warnings for) earthquakes in mid-America region; or a web crawling problem that was neglected by everyone passing through the project; creating the general solution for this took me to senior engineer position... and further, to team management. So far, I've created numerous utilities and scripts (C / C++ / Python), a complex image manipulation and postproduction suite (C++ / asm / CUDA, worked on this as a member of a team), some visualisation software: for custom equipment (Java) and voice emotion recognition (Node.js), and a few web based projects (Python with Django, PHP, Perl, Groovy - working with a team on huge CRM system) including also long team Java-based web scraping suite I both developed and managed the team involved. Lately I am trying to concentrate on web development, tinkering my own pet project: a space game and few experimental utilities in web application forms. I can work in and administer various operating systems (Windows, Linux, *BSD, Solaris... this came in handy lately when web development job turned into disaster recovery of remote server), use several databases (mySQL, PL-SQL) and quite a few programming languages; even created one myself, just for fun. What will be next, may be up to you. Feel invited.

Philippines - Last active: 2 days ago - Tests: 18 - Portfolio: 2

It was in 2009 when my daughter introduced me to oDesk. She, being a young fulltime mom then, realized how convenient and more rewarding it was to be able to work and at the same time be home and take care of her baby. I have, for more than 25 years, focused my energies on fulltime mothering, homeschooling and ministry myself, so I can't agree with her more. I also find oDesk as a wonderful opportunity to combine my family and ministry roles with my desire to further enhance my personal skills. My experience with oDesk thus far has been very rewarding, in terms of personal growth in knowledge and skills, and also in terms of opportunity to develop good working relationships with clients. My objective is simply to provide high-quality and dependable service. I am a diligent worker, preferring to work independently but delivering quick and timely service.

Russia - Last active: 9 days ago - Tests: 9 - Portfolio: 2

Hello, My name is Sergey, I'm from Russia, currently travelling around the world. I've started my career in developing software since teen, and now at my 28 I gained a lot of experience mostly in web development related subfields and various technology stacks. During my career I had a chance to work with different technologies and different team roles: as lead builded and managed a team (up to 7) to deliver successful product to market, as a freelancer and as a consultant. I believe in "10x performance gap" between average and best developers, which is supported by my clients feedback. Also I believe I have a nice learning curve which allows me to quickly dive into new and complex problem. I love to learn new technologies, languages, concepts and underlying math. Actually, I could do it for free, if it wasn't payed so well. Here's the list of tools I use with confidence: - HTML, HTML5 APIs (websockets, geo, webworkers, etc) - LESS and CSS - Javascript and jQuery as well as various Ajax implementations - backbone, requirejs, ender, angular, underscore, lodash, socket.io libs - nodejs, expressjs, promises (also, I'm in love with harmonyjs features) on a very deep level - mysql, where I know internals and love to use view, procedures and etc - couchdb, which I've studied all thru, including source code review and deep understanding of couchdb-specific features like replications, changes streaming and performance factors - mongodb, which I usually use with nodejs and mongoose - RabbitMQ, ZeroMQ - XML by XSLT transformations, where I have a great experience and feel fluent using it's paradigm. XSD skills included - Google Chrome, Firefox and Safari extensions and of course phantomjs - Designing and building nice REST apis, which are not mimicking rest concept, but really follows design principles - Integrating 3rd-party rest/oauth APIs in one single solid system, considering related issues like availability and etc - Designing and building long-running distributed system in data mining and processing - Hacking, bypassing and tricking - PHP > 5, which I prefer not to use, but still have many successful projects behind - linux other *nix systems administration and configuration. With a little help I can compile and install linux from sources for example or have no problems while setting up complex multi-server development environment, writing deploying scripts with bash or puppet, setting up monitoring and so on. Other things I've used to do or have a great interest in: - erlang, which has an interesting approach - RDF, RDFS, OWL, SPARQL, graph databases (like Neo4j) and triple stores (like jena, allegrograph, thinkerpop and many more). That's my main point of interest by now. I've studied all available software, math related to graph processing as well as relational and sparql algebra and related issues like data locality in graph, data storing, queries complexity, forward/backward reasoning problems and etc.. Currently, in my free time I'm building GPU graph processing snippets to play and get better understanding. So I would be very happy to see and join this kind of projects here, on odesk - C/C++/Java coding skills, which is required if one want to try newest approaches or link together code from different worlds, for example, bridge cpp library to nodejs. I don't pretend here for being good coder, but it helped me so many times, it's worth mentioning - Python, because there're coolest math, stat and science libs I've ever used. Python here is just a tool to access them. I prefer 3 types of jobs: - short but very complex problems, where deep understanding or wide set of skills is required - building project from scratch with well-defined features list - consulting in system design or problem solving I prefer to avoid to join projects in a late stage, because usually it means that I'll have to deal with previous developer's problems, not client's ones. So I will ask you to introduce me with your existing codebase in a first place before giving any feedback. Also I won't take team leading, because I don't have enough skills to perform remote team managing. Usually I pick up the project mostly not by company or project solidity or payment rates, but by how interesting or fun it feels for me. Unfortunately, I can't clearly define those 2 above, so I'm considering a wide variety of offers. Currently odesk is not yet my primary projects source, but I like it's reliability and have plans to move my activity here. Finally, I have no online availability problems and I can communicate with English in both written and verbal ways. Thank you, and I'm here looking forward for cool problems from you to solve.
