Jakub Zuchowski Agency Contractor

Ruby on Rails Developer

Poland - Tests: 5 - Portfolio: 7

I have been a Ruby on Rails programmer for almost 5 years now (since early 2010). I have worked with various Polish companies, including micro-teams and a Corporation. I focus mainly on back-end development, such as json based APIs and try to master the techniques of BDD. I am happy whenever I can break out of Rails` default presentation schemes, and complement its backend with a completely new presentation-oriented technology, like Backbone.js. Outside of Ruby I am interested in learning Python and (very recently) C. I have experience as both a team player and a self-sufficient developer. I always try to pursue the best solution and am keen on learning new technologies, especially when I can put them to practical use.

Sergey K.

Ruby on Rails Developer/Consultant

Russia - Tests: 2

Looking for a dev to join your team, do a code review or start a new project from the ground up? Look no further! I have extensive experience in creating and maintaining applications of all sizes. (From simple proof of concepts and MVP's to complex SAAS platforms). I follow best practices and latest developments in ruby/rails world, know most design patterns and anti-patterns and can use agile practices (TDD/BDD/CI) effectively. I'm used to work in a well organized environment (with github, fetures in separate branches, pull requests, code reviews, CI, staging and QA) and can help you set one up, or I can adapt to whatever process you use just as well. On top of that I've been working remotely for the last 6 years, so I understand importance of communication and very used to doing everything without hand-holding and micromanagement. Give me a task, I'll ask for clarifications if something is not clear and then I'll get it done as fast as possible while maintaining code quality. A bit of technical stuff: Over the years I've dealt with pretty much everything related to development of web applications. Ruby 1.x, 2.x Rails 3 and 4 (including migrations from 3 to 4): file storage (AWS/Google) and file processing, SQL (postgres, mysql), authorization and authentication (Devise, Cancancan), payment services (Stripe), background processing, scheduled jobs, internationalization and timezones, complex mailing systems, caching and performance optimization, rack middleware and rake tasks, interactions with all sorts of APIs (Google, Adwords, Facebook, Twitter, Rets, and 10+ others) and all kinds of testing (functional, performance, feature and even a/b). I also know front-end quite well (JS/CoffeeScript/jQuery&plugins/React, Bootstrap/ZurbFoundation, Haml/Slim/Saas) and know my way around unix systems (can configure and deploy apps if needed). A very simple app to show you an example of my code: https://github.com/rovr/facebook-by-category

Alex Fortuna

Lead/Senior Ruby on Rails Developer, Mentor

Russia - Tests: 9 - Portfolio: 3

I've been developing in a variety of languages on different platforms over the last 15+ years and I'm still enjoying it. Programming is my lifelong passion. The things that excite me the most as a developer are those innovative, unique and technically tricky. The things I try to achieve as a team leader are just these: efficiency and harmony. I see a successful product as a harmonic combination of well-designed software AND a well-tuned team involved in its creation and subsequent development. As Upwork freelancer I specialize in dynamic Web application development using Ruby on Rails and JavaScript (AngularJS, React.js), commonly in a position of CTO or lead developer. I prefer to do base/architecture stuff myself and direct the team to do regular parts. I've got all sorts of experience required for both hands-on work and mentoring: 15+ years overall development, 9+ years Ruby, 7+ years Rails, 10+ years Unix/networking, 5+ years Git, TDD, etc. etc. I believe that QUALITY is the key priority if you want sustained growth. I provide it, I motivate or otherwise make others provide it. It takes time? Yes, but... "Good cooking takes time. If you are made to wait, it is to serve you better, and to please you." ——— Keywords and samples ——— Solid, long-term, clean, well-documented, maintainable, resilient. Please read my clients' reviews for more live keywords. Also, please take a minute to look at my code samples: https://github.com/dadooda/code-samples. There are also some open source contributions in the neighboring GitHub repositories. ——— The DO statements ——— If any of these statements are relevant to you, please DO apply as we'd probably get along together nicely: * "We had tough experience with Indian developers in our previous project. This time we want to begin by building a solid base which would guarantee us stable growth for the next 3-5 years." * "We have an ongoing issue in our distributed team: every time a developer leaves, the new one spends weeks becoming familiar with the project. We need someone to take care of connecting new developers smoothly." * "We like our current developers, but they seem to try new fancy things out of boredom or curiosity. We want to balance it somehow to stop losing momentum because of thoughtless fun experiments." * "Our current developers are okay writing code, but they get annoyed when being asked to explain or describe something, even to one another. We want a lot more sustained awareness and shared vision between our team members." * "One of our developers likes Apple, another one is a PC/Linux man. Both are great, but they keep arguing over their preferences which is a productivity killer. We want someone with authority to deal with them both." ——— The DON'T statements ——— If any of these statements sound true, please DO NOT apply since I'm probably not good enough for you: * "We'll start our new project with cheap student developers. It's then easy to invite a senior guy for a week or two to correct all of their mistakes." * "We don't need any written specs or documentation. We have Agile, Scrum, XP, pair programming and Slack chatroom instead." * "Writing project description is a waste of time. We'll start posting Scrum stories right away. A good developer should read our mind." * "We'll use NoSQL in our new project. Why? We don't know, but blogs are full of statements that it's better than SQL." * "We've just completed the visual design of our new application. Now we need someone to write code for it, which is a trivial technical procedure." * "We believe that this alone guarantees our code to be clean and solid: keeping methods shorter than 5 lines and keeping classes shorter than 100 lines." * "We've had a lot of trouble managing distributed teams. This time we want ONE great developer to handle everything. We can definitely control one person." Thank you for reading this far. If you're interested, post a job for me or send me a message. Cheers!
