    Back-end and front-end dev and photographer

    Ukraine - Last active: 6 days 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.

    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.

    Expert web developer with 20+ years of experience

    Mexico - Last active: 04/05/2014 - Tests: 5 - Portfolio: 2

    I started in software development about 18 years ago, first with languages like BASIC, Pascal, C++, and later Visual Basic. It was like love at first sight, and since then I haven't stopped learning and being amazed at what we accomplish as an industry each passing year. About 12 years ago I moved to web development out of dislike of the .NET framework (the natural progression for me at the time), and started learning PHP. Over the next few years I was always looking for ways to make development with PHP easier, as it wasn't a very elegant language, in my opinion. Then, about 6 years ago, I discovered Ruby on Rails, and that re-ignited the passion for software development in me. Not that I lost it, but I was increasingly becoming frustrated with PHP. So my objective is to continue on this path of learning and growing, and at the same time, help you implement your visions and dreams with the experience and expertise I can bring to your projects. PS: I have experience in implementing both Intranet systems and public websites and applications. I've developed internal apps for automating systems like payrolls and document management. I've created several websites, and web apps too, and my current "flag-ship" personal project is a portal for the educational sector in Mexico -- http://eduportal.com.mx/ and http://eduportal.mx/expo/ Currently I specialize in working with Ruby on Rails, and I have experience in PostgreSQL, MySQL, SQL Server, and of course, SQLite :) I'm also experienced in HTML, CSS, and JavaScript. Now, if you don't care about the implementation details, just leave it to me and I'll deliver to you a top notch project within your specifications in no time. 100% satisfaction guarantee.

    Web data expert--programming, applications, social media data extracti

    United States - Last active: 06/11/2012 - Tests: 2

    Do you need help turning the unstructured web into meaningful data? Example Applications * Crawling and extracting data from websites * Analyzing Twitter data to find people that are interested in your products or services, or people that are talking negatively about your competitor's products * Correlating social media sentiment with stock pricing * Organizing documents from a local LAN for a lawsuit * Leveraging Machine Learning, Artificial Intelligence, LSI and Bayes Theorems to analyze "big data" and find trends Over the last 3 years, my company and I have built core expertise in crawling, data extraction, classification and machine learning. And, as we finish building our new marketing analytics commercial application, I'm looking for 1 to 2 projects that would fit and be synergistic with our current capabilities and development focus. Advantages of TEMPUS Group 1) Cost. In exchange for me being "particular" about the work we do, I'm offering a dramatically discounted rate from me and my team (over 60% off) of what we currently charge our existing customers (rates start at $125/hr). And, you get the benefits of working through ODesk. 2) Integrity and Pedigree. I have a history of execution and delivering value. In the past ventures I've been involved with, I've returned over $400 million on $65 million in investment. I understand what is "worth doing" and I won't burn hours if it doesn't help you achieve your goals. 3) Expertise in our Core Discipline. We are very focused on this particular need. If you want a website built, you're best bet is to hire someone for far cheaper. However, if you have crawling/data extraction/enrichment needs, we're focused and can help you deliver this faster than you thought possible. 4) US-based with US-based execution standards. You will most likely work with me (William) daily, and you will have my email, phone, cell phone, Skype and other IM so you can reach me anytime. And, I usually answer my phone unless I'm hard at work on a project. ODesk is about cheaper labor. That's true. But, isn't the total cost the true metric? We won't waste your time. We won't waste your money. And, if we can't get the job done, we'll tell before we commit to the project. Reach out to me, I'm happy to talk about your needs and see if we're a fit.

    Web developer

    Thailand - Last active: 1 day ago - Tests: 12 - Portfolio: 12

    Lately my work is about integrating Bitcoin-related functionality in websites or developing special purpose apps, like a bitcoin trading bot or a websocket chat. It involved various technologies: node.js, websockets, Ruby, Sinatra framework, Blockchain.info API, PayPal API. During the years of my work prior to this I've performed a big variety of tasks in developing and reworking websites. This involved a lot of programming with PHP+MySQL, layout works with HTML+CSS, Javascript (with and without jQuery), AJAX. I had experience working with various CMSs: OpenCart, Joomla!, Wordpress, MODx Revolution, DataLife Engine, SimplaCMS, self-written websites. Also with different frameworks: MODx, Yii, also self-written MVC structures. I also use regular expressions (RegExp) fluently and have quite some experience with that. I've integrated a number of payment systems in several websites, which included PayPal, Bitcoin (native and via Blockchain.info API) and russian WebMoney, Yandex.Money, QIWI, Robokassa. All payment processors utilize mainly same principles, so it's no problem to learn and integrate something new quickly. My work included creation of web grabbers and parsers that process information from external websites, for example to fill up an online store database. Also setting up and administrating Linux/FreeBSD VPS servers: installation and configuration of Apache, PHP, MySQL, Python and some other uncommon software. Aside from pure web, I've developed Python and Ruby scripts for various services. A part of that was developing Bitcoin-related services, including API communication with bitcoind daemon, automated receiving/sending Bitcoin payments, trading on BTC exchanges via their API, and other stuff. I'm looking for interesting work opportunities that would let me develop my skills and acquire new ones. Cryptocurrencies are especially interesting to me, but if it's not the case, no problem. Most likely I can be useful to solve your programming issues, so feel free to contact me.

    Web Developer

    Germany - Last active: 2 days ago - Tests: 4 - Portfolio: 1

    Hey there! I'm a freelance web developer based in Germany. Over the last several years I've been building websites using PHP, Ruby, Rails, jQuery, Javascript, Bootstrap, CSS3, HTML5 and more. I have experience in working with such PHP frameworks as CodeIgniter and Laravel. I also enjoy scripting and automating tasks with the help of Ruby or Python. So I would be more than glad to help you scrape a few thousand web pages in order to get the data you're looking for. I'm currently a student at a German university, so I have to deal with both German and English on a day-to-day basis. Moreover I'm a native Russian speaker. So feel free to contact me in case you are looking for a really human translation of anything involving any of these three languages.
