Vetted Ruby developer in Ukraine (UTC+2)

I have overall 18 years in the IT industry and 11 years in software development and development operations. I worked at product, outsourcing, and out-staffing companies which are present at the Ukrainian and global markets. I occupied the next positions of Networking Engineer, System Administrator, Software Engineer, Senior Systems Engineer, IT Department Lead. Industries where I did provide development services are Logistics, Financial technologies, E-commerce, Electronic education systems, psychological healthcare, entertainment, restaurants and hotels. Sometimes I'm developing open source software. As option I'm looking for switching to the Python as main language, ideally at projects where present Ruby. Also I’m developing my own projects, prototyping software architecture solutions, developing technical solutions for interesting engineering tasks, learning interesting and perspective for me technologies. Familiar with electronics, microcontrollers and development of firmware, using it as a hobby. My technological expertise includes: * Backend software development with Ruby and any Rack frameworks or built from scratch Rack applications, development of gems, libraries and utilities. My program code is written by best practices and style guides using Rubocop(for every technological part of application) and other required linting tools. I'm auditing code for security vulnerabilities and maintainability on a regular basis as part of my development cycle. Also I am able to use Python, Elixir, C/C++, Lua as secondary languages. * Frontend software development with Node.js, JavaScript and nowaday transpillable languages such as EcmaScript 6 and 7, TypeScript. I'm using webpack, rollup, babel and any other bundlers, transpillers and asset compilers. Using ESLint, TSLint at my work. * Development Operations and System Administration. At my work I'm using AWS, Heroku, Azure and other cloud solutions. I'm using Hashicorp Terraform for infrastructure provisioning, Ansible and shell script for deployment of system tasks and delivery of software building blocks to server, Capistrano and similar tools for application deployment to the server. Familiar with Kubernetes and Docker swarm container orchestrators. Familiar with virtualisation hypervisors such as libvirt, KVM, Zen, VMware vSphere, bhyve/xhyve. Familiar with next CI/CD tools: Github Actions, GitLab pipelines, CircleCI, Semaphore CI, [Drone.io](http://drone.io/) CI. I have experience of building bare metal virtualized clusters and physical networks within virtualized zones. * Testing. I prefer to use RSpec or minitest for Ruby tests. Jest, Cypress or ViTest for JS testing. I'm implementing Unit tests, Acceptance tests, Requests tests, Integration and scenario tests, black-box tests. I prefer to cover applications as maximum as possible, but within adequate limits to not lose maintainability and scalability of the system. * I am practicing Agile methodologies such as XP, Scrum, Kanban. Even for my own solo projects.

Alex S.

Vetted Ruby developer in Ukraine (UTC+3)

Software engineer with over 12 years experience in developing web and mobile apps. UnitedDevForces was the company I founded with a friend of mine, and while working there I’ve learner not just how to code better, but generally how make projects successful. My duties included full cycle of communications with client starting from gathering business requirements and up to handling over finished product. All projects I worked on got some benefits. Somewhere it was just coding, somewhere project management, but without me working there I don’t think they’d be as good as they are. But most benefits got my own product - [https://planlike.pro](https://planlike.pro/) I was leading it all the way from group up and all aspects were either created by me or implemented by me. In my everyday work use variety of languages and tools such as Ruby(Rails), Go, Elixir, JS(Vue, Ember, Angular and others), Flutter(Dart). I am good at Planning, CodeReviews, and Problem Solving.
