    Ukraine - Last active: 4 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.

    Engineer in Computer Science - Developer - Research

    France - Last active: 2 days ago - Tests: 15 - Portfolio: 1

    Hello, I am a 27 years old engineer in Computer Science from France. After graduating from the Institut National des Sciences Appliquées of Rennes, I moved over to Sweden to follow a master program on Mobile Systems. Meanwhile, I was also working as a freelance web-developer/project co-leader for a Canadian company. While learning, I participated as a trainee to many professional project and learn to be flexible both in my ways of working in a team and on the technologies to use. Indeed, even so my major programming languages are Java and PHP, I could easily learn C# during my master thesis in Sweden and build up a nice piece of software to work with Sifteo cubes. Software architecture and system design are two of my strong background points, thus I thrive in realizing project from the beginning until the end. My professional experiences involved many non programmer and non computer scientist customers and allowed me to train establishing their needs and to translate them into sprints, backlog and deadlines. I also believe that knowledge in computer science without knowledge of the real world are wasted hence my interests for books, sail, roller-skating, ice hockey as well as environmental questions for instance. Looking forward to working with you.

    Full-Stack Developer Of Scalable, Beautiful Web Apps, MVPs & More

    United States - Last active: 1 day ago - Tests: 2 - Portfolio: 4

    Hi, Many come to oDesk/Upwork looking to hire a cheap programmer to quickly throw together a piece of software. I'm the person you come to after you've worked with cheap programmers, spent tons of money anyway since your project took way longer than expected, and you've just realized that the software you ended up with is a house of cards because it is full of bugs and built on a poor architecture, leaving you with something that you can't scale or maintain, let alone build upon to add the valuable features that your users are requesting. Or, I'm the person that you come to in the beginning to get started the right way, with a lean, scalable, fast, custom web application that you can grow 100x and easily adapt to meet your users' demands. Either way, I'm here for you. I'm Austen. I’m 29. I’ve been a software engineer and entrepreneur all of my life. Every day, I build custom web applications for myself or other people. -------------------------------------------------------------------- Things I Do Best: -------------------------------------------------------------------- • Full-stack javascript development • Exceptional graphic design. • Finance and fundraising for start-ups. • Be a stand-up individual that works tremendously hard to create value for you, and bring you success. -------------------------------------------------------------------- Services I Offer: -------------------------------------------------------------------- ** I Build Web Applications (MVP / Prototype / SaaS) ** First and foremost, I build immensely scalable, maintainable, beautiful web applications that operate at the lowest possible cost. I do this every day, for my own start-up or for other peoples' start-ups. If you are looking for an AWESOME Minimum Viable Product/Prototype, which can easily scale to meet a growing user base, I can build it for you. Since, I’ve done this so much, I even have my own starter templates that help me build scalable and cheap prototypes as fast as possible (https://github.com/servant-app/JAWS). ** Hourly Consultations ** Often, I get requests for advice from people looking to build a piece of software for their existing company or for a new start-up. They usually want to know how to proceed and which tools to use. So, I tell them. This involves a long phone discussion and then I spend a couple hours clarifying my suggestions in a Google document, which the client keeps for reference. When I started building web start-ups, I did not have access to people who could give me clear advice. So, I enjoy doing this for others, and give the best and most actionable advice I can. If you don’t want to hire me because of my price, that’s fine. I can at least inform you what to look for in a developer, and even write up an oDesk proposal for you. Also, if you are considering hodgepodging existing tools together because it looks deceptively simple (e.g., Wordpress + plug-ins), please talk to me first! If you have already hodgepodges something together and have now realized it’s breaking, it’s incredibly difficult to fix, you can’t pivot to meet your customer’s demands and you need to transition, please contact me, I can help you. ** Building/Consuming REST APIs ** This is the era of web APIs. My own start-up is a powerful API-As-A-Service start-up. I can build out a scalable REST API for your company. ** Other Stuff ** I like doing other stuff, if it’s interesting. But the services above are what I'm best at. -------------------------------------------------------------------- Technologies I Use: -------------------------------------------------------------------- • Javascript • Node.js • Express.js • Restify • DynamoDB • MongoDB • PostgreSQL • Redis • Github / Git • AWS Lambda • AWS EC2 • AWS Elastic Beanstalk  • AWS S3 • AWS Cloudfront • AWS SES • Heroku • jQuery • Angular • React • Gulp • Nitrous.io • Photoshop • Illustrator • After Effects • Stripe API • Google APIs / Google maps / All of Google’s API • Twitter API • Facebook API • Twilio API • Tons of APIs! • Mailchimp • Mandrill • Web scrapers • Various CMS systems • & More! -------------------------------------------------------------------- More About Me: -------------------------------------------------------------------- I live in Oakland, California where I work part-time on my own start-up (https://www.servant.co). Building a business takes a while, so I work 4+ hours/day on oDesk to help pay the rent. So far, I've had only a few clients because they have not let me go. One of my oDesk clients even became an investor in my company :) Contact me, I'm always available :) Let's build something awesome! Kindest regards, Austen Collins
