    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!  less

    I have been developing a lot of projects using the MVC pattern for more than 6 years. I began with development on CakePHP (~1 year), then I developed on Symfony (for 3 years). Also I have strong experience in using Bitrix, Drupal, Joomla and Laravel. In addition I have been studying such programming languages as Ruby and Python for a couple of years. I have knowledge about Django, Flask and Pyramid on Python, and Sinatra and RoR on Ruby. I think Ruby is the most agile language and RoR is the most convenient web-development framework. So I decided to change my profile to work with RoR. Also I have deep knowledge in the related areas, such as HTML, js, jQuery, AngularJS, and in such relational databases: MySQL, PG, SQLite. I have a lot of experience in testing and deployment of applications, software setup, monitoring of servers and services.  less

    Hello, my name is Patrick Sagan. I am experienced Rails and Ruby developer, software architect who can provide you remote programming services and help create your product in IT area. I can work on existing systems or build new one from scratch. I have deep experience in web development and software architecture. In past I was playing with php (and got some certifications listed below) but currently I'm focused on ruby, rails and sinatra. I have small office based in northern Poland (Pomeranian District), so I work remotely and worldwide. Wherever your company is placed, if it is USA or UK I'm flexible in working hours. I speak English so do not hesitate to contact me. My values: - I am focused on high quality of code ("developer's friendly code") and solutions. - I am focused on delivering great user experience. - I am focused on getting things done, more stuff done and less theoretical words. - I am focused on self-development (currently I am using https://www.codeschool.com/paths/ruby to find new approaches.) - Regarding to building products - I am big fan of rules presentend in "Rework" book of 37 signals (http://37signals.com/rework) - Deep understanding of business requirements - so I build code for business not just to fulfill programming ambitions, which are often different than business requirements I believe that working in company which has similar values gives synergy effect for both: company and employee. Please feel free to check my website to get more information about me and how I work: http://www.dev4.biz. You can also check my another site: http://www.rails-dev.com - with rails recipes - this site is just launched - not so many content there yet.  less
