    Engineer in Computer Science - Developer - Research

    France - Last active: 13 hours 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.

    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.

    Planing, Design and Development of iOS Apps

    Japan - Last active: 13 hours ago - Tests: 1 - Portfolio: 8

    My name is Tonriké, or Toto for short. I'm independent freelance iOS developer and designer based in beautiful city of Kanazawa in Japan. I help companies and entrepreneurs to plan, design and develop iOS applications, usually — from scratch. This covers everything from information in-take, analysis and architecture to application prototypes, user-interface design and software development. I also offer those services separately; however, I will not do UI design without comprehensive UX consulting. Technically, my skill-set covers anything from iOS Foundation frameworks to advanced topics like image processing and digital signal analysis. I already develop and help community to research Swift Language and latest Apple technologies. My experience as iOS developer starts right after iPhone SDK was debuted in 2008. Fascinated by product design and information architecture, I also started to design user interfaces and planing software products in 2009. In 2013 I was offered to teach "User Interfaces for Programmers" in Caucasus University in my hometown, Tbilisi, Georgia. That's what I did and as result, ended up creating whole syllabus which is still in use by university. I'm also fluent with many other technologies around those languages: Ruby, JavaScript, Go-lang. I charge what I charge because I'm one of the best in business, and results I provide are not disposable. "Fire and forget" is not my style of working and many returning clients are prove to that. I do not accept "I need Instagram clone for $1000" jobs, those are for scammers and "developers" desperate to ruin their reputation for little money. In short: If you want high quality, fully-working, maintainable and well-planned product with pre-development consulting and proper design, than contact me.
