    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!

    Linux sysadmin, cloud deployments specialist

    Czech Republic - Last active: 1 day ago - Tests: 9 - Portfolio: 1

    I would like to offer you my deep knowledge of servers hardware and software, which allows me to fine-tune servers according to their roles, and my ability to anticipate and solve problems in shortest time possible. No Windows please, Unices only, Linux preferrable. Lately my main point of interest has shifted to deploying and maintaining web projects in cloud environments. I am developing monitoring / management tool ( http://m-script.org ) and supporting existing installations, but I am very well familiar with all well known alternatives from both monitoring and cloud management side, so no problem to implement any of them. The point is, I know very well how it works. And how it doesn't, too :) I am interested in any system administration work, especially in cloud environments. The more challenging you setup is going to be, the better. Automated scalability, cross-clouds deployments, combination of traditional and dynamically scalable resources, DNS/Geo balancing - everything is possible, just let me know your needs.

    Rails Dev With Diverse Skill Set

    United States - Last active: 7 days ago - Tests: 5 - Portfolio: 5

    Hey, what's up? Thank you for reviewing my profile, I'm glad you stopped by! My name is Dave and here's the skill set I can bring to your project or team: Ruby on Rails Development - Experience with Heroku, Postgres, Devise, Pundit, Paperclip, Geocoder, etc. Front End Development - Bootstrap, Sass, Less, and a little bit of AngularJS Graphic Development and Retouching - 11+ years of Photoshop experience with an extensive focus on photo retouching, complex compositing, and stylized post production. Other Cool Stuff - Audio engineering, video editing / post production, marketing, and I'm a damn fine party planner! But wait, there's more! I also speak fluent English, am on EST time, and according to the Dali Llama, on my death bed I'll achieve total consciousness, so I got that going for me. On a serious note, I am looking primarily for ongoing rails positions that will challenge me and expand my knowledge. I also know that being able to fill some gaps when needed can be a huge benefit. I am happy to jump in and be of help in a range of areas outside of web development if needed, such as marketing and content creation. Finally, and as I would expect from anyone in web development in this day and age, I am very familiar with Wordpress and able to assist with just about anything a project could require. I would love to chat with you more about your thing / project / hopes and dreams / and the like... So please hit me up with a message and let's do lunch. Thanks again and talk soon!

    Web Developer - Proficient in PHP, Laravel, Javascript, Ruby on Rails

    Portugal - Last active: 1 month ago - Tests: 4 - Portfolio: 3

    I've worked closely with world-class companies throughout the development of outstanding platforms that have been used by thousands. I'm proficient with PHP and I'm also a Laravel early-adopter - I've been using it since early version 3. I've developed countless applications with Laravel, attended the Laracon conference in Amsterdam and I've written several tutorials that have helped hundreds of other developers. In addition to PHP, I've also used Ruby on Rails extensively to develop complex web applications with full featured test suites. Being a Software Engineering student, you'll be sure to get solutions that are well designed, easy to scale and develop upon. I've taken a CAE (Certificate in Advanced English) by the University of Cambridge and passed with flying colours. Communicating with me won't definitely be an issue. Looking forward to working with you on your next web app!
