Developer skills

• Ruby, project example
  Ruby is excellent way to interpret your thoughts and ideas to any machine through Object-oriented programming tools and with the assistance of unique Ruby community (who also creates awesome gems, patterns, education resources, etc.)
• Ruby on Rails, project example
  I think about RoR like a General Contractor. First of all I set a task, decide what models should I have. Second step is define key scenarios of an app. Next I draw views projects that help me understand what gems, frameworks would be better for front-end (Webpack + Bootstrap + Puma looks great for new apps, but sometimes the best way to choose Asset Pipeline way if I won't use a lot of CSS, JS, JS libraries) and it would be connected through controllers and routes. After all it is time to code, test, edit multiple times and coordinate with colleagues, deploy to server.
• WebSocket, project example
  There is opportunity to use Aplication Cable framework, directly in RoR, that based on WebSocket technology. Kabulchat app is a bright example of simple chat system where users get messages without refreshing HTML page or element: back-end controllers ('channels' - convetntionally for RoR) + Front-end (JS/JQuery/Coffeescript files in Asset Pipeline) + DB (Redis for production for the best user experience).
• Web scraping, project example
  Nokogiri and OpenURI gems help to retreive data from the Web according to individual settings and then Ruby builtin methods allows to transform this data to any preferable format (output text to termianl console, .xlsx tables, etc.).
• Tests (RSpec), project example
  Currently I use RSpec tests (with FactoryBot and Capybara gems) for checking RoR models, controller actions, policies, etc. For me tests are 'internal auditors', so 'due diligence' of an app is good technical and business practice, so I am on my way to learn RSpec and other tests more deeply.
• HTML + CSS + JQuery, project example
  Front-end is very important part of any web app because customers interact with app through web pages.
• Vanilla JS
  JavaScript = 'brain' of Front-end. I'm just at the beginning of the learning JS and I plan to improve my JS skills.
• Bootstrap + Webpack
  Webpack + Bootstrap = one of the best way to organize Front-end. Webpack has excellent performance optimizations, it really helps for working with JS and JS frameworks, and Bootstrap is intuitively understandable HTML-CSS-JS libtrary, so it is a pleasure to work with Front-end.
• PostgreSQL, SQLite, Redis
  Almost all web apps interact with object-relational database systems for saving and retreiving data. For production mode I use PostgreSQL because of client server architecture and for development simple SQLite that is embedded into the end program.
• App deploying to vps ( Heroku, Digital Ocean + Nginx)
  One of the purpose of web apps is remote access for its functionality, so deploying apps to IaaS (Digital Ocean) and PaaS (Heroku) solutions is essential and ehjoyable part of technical sophistication.
• AWS, Google Cloud Platfrom
  Diversification of media needs in cloud solutions that make app developing more flexible.
• Kafka
  One of the necessary tools to develop APIs.
• Kubernetes
  Effective way to manage projects in remote servers.
• Docker
  Docker has Linux kernel's functionality and uses resource isolation, so it helps for app developing in teams.
• Git & GitHub
  Git and GitHub are essential part of developing process — you make key notes (commits) after updating or fixing of app code and that is why your way of thinking becomes clear for other developers and for you in future.
• Logz.io, New Relic, Helios
  It really helps to investigate and fix errors.
• Linux / Windows
  There are much more commons (for developing purposes) between Linux and Windows since WSL2 was presented.
