    Team Lead, Senior Ruby on Rails, co-founder at RM

    Ukraine - Last active: 1 month ago - Tests: 1

    I'm a Tech Lead with about 8 years experience in web-development and about 4 years in Ruby on Rails. I have in portfolio more than 40+ finished rails projects from social platforms and e-commerce to SaaS. I'm self motivated, can solve complex tasks in a short time. In the past two years my main roles were architecture planning, choosing the right technology stack using the client's requirements, development management, team management I like Agile and use it every day - iterations, scrum daily meetings, retrospectives. I like confident code and TDD/BDD. I'm experienced in RSpec, Capybara and Cucumber. Often I help clients to understand what will be the best development approach for them. Do they need only MVP or there is a sense in building full version. What technologies are best for their project. Plan deadlines and budget. I'm very familiar with AWS technologies stack - setup EC2 instance from scratch, configure balance loader(EBL), setup push notifications service(SNS), emails(SES), database instances(RDS), and other services I have an experience in buiding a high-load applications, huge processing centers with 1,000,000 processed jobs daily(in Sidekiq), PostgreSQL database size more than 500GB and everything places on EC2 instance with 32 Cores and 68GB RAM. That was very excited. I'm a fun of continues integration and continues deploy practices. I also have experience in front-end development: JavaScript on advanced level, canvas, CoffeeScript, web-sockets(socket.io) with node.js back-end, backbone.js, Ember.js In the past years there is a trend to have an application with RESTful JSON API built in Ruby on Rails. I have experience in building more than 5 different APIs for different projects. Some of them were versioning and have up to v4. There is always a challange to support old versions, but we successfully doing it. Some have HIPAA protection, one application had a really complex structure of API URLs but it was very easy to work with it in the end since we built it human readable. Thanks for you time!

    Sencha Ext JS 5.1 / Sencha Touch Expert

    Thailand - Last active: 10 hours ago - Tests: 2 - Portfolio: 4

    The last 5 years of my career I have worked with products of Sencha (Sencha Cmd, Sencha Touch 2.3, Sencha Charts, Ext JS 3.4, Ext JS 4.2, Ext JS 5.x). I was fortunate to work with highly diversified range of tasks. The list includes: - upgrades of applications (Ext JS 3.4 -> Ext JS 4.x -> Ext JS 5.0), - mobile application development (Android, iOS, Sencha Touch), - using Sencha Charts, - integration of third-party libraries into Sencha products (OpenLayers, Highcharts, jQuery, Google Maps, Yandex Maps), - code testing in Selenium, Siesta, Sinon, YUI 2, - refactoring, - fully project reimplementation (rewrite a project from scratch, rewrite a project from JS to CoffeeScript), - consultations, - and much more. Javascript is one of the few languages that gives too much room for creativity, a space to express their thoughts. And unfortunately too easy to go far from the correct direction, from the decision to be easy to understand for other developers. That is why I firmly believe in the need to using hard coding standards and official recommendations. It's not important tha you are using for yours projects - PHP, RubyOnRails, C#, Ajax, XML, JSON, bla-bla... I just said you: Yes, I can do it! It's OK! I know well Git, worked with Subversion, used many task trackers: Jira, Redmine, YouTrack, and others, can't remember all.. Also my expirience included development of a mobile apps using Java for Android. If you need in one of the best, you're welcome!

    Jaap Van Hardeveld

    End-to-end web developer specialised in Javascript, HTML5, UX/UI, Node

    Netherlands - Last active: 10 hours ago - Tests: 2 - Portfolio: 4

    I love making apps, like my latest project: Rallypoint, sort of like Stack Overflow for private teams, with a focus on quickly moving on and not wasting time. www.getrallypoint.com I can get passionate about perfecting a front-end flow and layout with HTML / CSS and Javascript, designing entire back end systems using Node.js / MongoDB or the good old PHP / MySQL and turning raw ideas into reality. I'm goal oriented and have no trouble constantly zooming in and out. I think about the product from end to end, from owner to user. Entrepreneurship is in my blood. Ever since I was just a teenager I worked on getting better at web development. I'm always looking for ways to challenge and improve myself. Over the years I've gotten heaps of experience in: * HTML / CSS / LESS / SASS * Javascript, both front and backend (React, Node, Flux, Backbone, Angular, Hapi, Express etc.) * PHP * MySQL / NoSQL database design * MVC Frameworks (Laravel, CodeIgniter, FuelPHP, etc.) Ofcourse I'm proficient in any tools that I need to do my job properly. I use Slack, Skype, Email and Google Hangouts to communicate, Sketch and Photoshop to work convert designs from mockup to HTML, Trello / Basecamp / Highrise for project and client management. I've got a smartphone and tablet and am hardly ever disconnected.
