I am a web developer primarily specialized at Ruby on Rails. I try to write clean and readable code without dirty hacks and Perl-like obfuscation, making it available for future maintenance and updates. I also prefer to use available libraries for common things instead of reinventing the wheel. I did various Rails project in the past from simple landing pages, which are mostly HTML with a simple logic to collect user contacts, to a complex video hosting website. Now I'm looking for long-term work on projects with a good workflow, code reviews and clean task descriptions, where you know what you need and I know (or can find/learn) how to make it work. Expected working hours are up to 20 .. 30 per week, but can be 40 hours for some period of time. My main skills include: * Ruby on Rails 4.x and newer. * Working with various gems like carrierwave, nokogiri, simple_form, rubycas/devise, cancan and many others. * Working with and understanding various APIs. * Building API-only backends. * Working with legacy code. * Some Javascript and jQuery. * HTML and CSS, including some CSS3 features like media queries, shadows and simple animations. * Configuring and maintaining Debian-based Linux distributions such as Ubuntu and Debian itself.
