So, no surprises :) I’m a full-stack Web Developer (with 7+ overall development experience). Pretty good at Ruby(Rails, Sinatra, Grape, Sidekiq, Rspec, Cucumber) and databases/queues: MySQL, Postgres, Redis, RabbitMQ. As well as infrastructure technologies and deployment tools: incl. Linux, Nginx, Git/Gitlab, Docker, AWS. Frontend: AngularJS & other MVC/SPA frameworks I also had a wide experience (about 3 years) with PHP(Zend, Yii), Magento & E-commerce. Easily can start a new project from scratch alone or in a team (lead and mentor a team further), or level up your legacy code as well My specialties and present focus lead to web apps and backend, Web Services & API’s, Ruby/Rails; Actively curious about new messenger SaaS APIs, NLP, and AI. As well as backend alternatives such as Elixir/Phoenix (recently set up a brand new dockerized microservice - already run-in production)

Snr/Lead JavaScript Angular Developer

Remote work, Ukraine · $5000 · More than 10 years of experience · Advanced/Fluent

Pro in JavaScript, Angular and Web Development. Strong sense of great UX/UI. Also had some experience with React, Vue.js, Node.js. Mature specialist, 14 years in development. Big overall experience in industry creating apps of any size in product and outsourcing companies. More details are in private conversation and my CV.

Angular.js, AngularJS, CSS3, HTML5, JavaScript, Node.js, React, vuejs, Angular, Angular 6, webpack, JSON, TypeScript, REST API, AJAX, Git, Bootstrap, Jira, OOP, HTML, CSS, MongoDB, es6, LESS, SASS

I have a proven track record of exciting projects which are fully described in my CV.

I consider only remote work and projects. I prefer to work with a particular product, dive deep into details, and help it grow with wise technical decisions and implementations. I'm not ready to be involved into a bunch of projects in parallel "1 hour there, 2 hours over here". It's unproductive from my standpoint, and not an optimal place for my character and skillset. COMPENSATION (please read this!): The bare minimum from which I may start a communication with your company is $5000/mo after taxes. If your budget is tighter than that - do not write at all. Let's save some time to everyone. I believe that a fair offer will be in a range of $5000-6500/mo after taxes. Yes, I know it's pretty broad, but each company, product, requirements and team composition are different.
