    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: 1 day 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.
