Full version

I’ve been working in web development for 10 years, the last 6 of which I’ve been specializing in Ruby on Rails. Before that I’ve been creating web projects with .Net C#. Currently I’m getting more and more interested in mobile development, so since the summer of 2016 I participate in mobile app development with React-Native.

In my previous job I started as an apprentice programmer. With time I became the head of a software development and testing department, in the company’s startup branch. I gathered project development teams, where after development of initial projects’ versions we passed them to another team and began new ones. Many times I’ve been a scrum-master in various teams. At the same time I learned Rails and offered the management to change the platform we use. The idea was approved, I gathered a new team and since 2013 all new projects in our department were implemented in Rails. During 2014 we also taught RoR to one more team (3 people).

After I quit there were 3 small fully autonomous teams remaining, each of them working in 4 task flows by creating new projects and supporting existing ones. We usually produced 1-2 big systems per year, which was a decision of our holding’s management.

Also during the year I worked in a small company engaged in various startups at the CTO (remote). I’m currently working as a freelancer (remote, since the spring of 2017) and also making several projects on my own.

More information about these below.

I also have experience working with the finances. At first I was one of the developers, and later an author of all billing projects in service. I optimized and improved a non-stop working billing system with a several million dollars monthly turnover. I also designed and developed a billing system distributed between multiple servers. In the billing I used an interesting approach to aggregate a huge amount of operations using indexed view in MsSql. After transferring to RoR in all projects we use our own standardized billing with financial reports for accountants and everything needed in the document flow - acts, closing documents and etc.

Shortly on my RoR skills: full stack, a little closer to the backend part.

I usually use: rails4/5, ruby2+, coffee, sass, slim, rspec, sidekiq, unicorn, capistrano, pusher/faye, activeadmin, postgresql

In mobile development: React-Native For automated server setup: chef Environment: mac, vim, github

I’m a Kanban fan. In my free time I work on the Agile Season service ( - the code is available, so one can see examples of my work here). I also do my best to estimate time requirements professionally, a couple of times I taught my colleagues - product managers and lead developers (

I’m paranoid when it comes to testing, in my work projects test coverage is usually 96-98%. I promoted this approach in the company I worked at and also taught it to the programmers there. Here’s a presentation I used, with examples and tasks: (it’s in C# which is still used in the company).

I’m rather impatient when it comes to reccurring tasks, so in the teams I worked in we automated everything, from CI/CD to server setup. Well, there was no other way: lots of projects, many servers, a few people, so we had to make the support take as little time as possible.

I graduated an art school (beside my main degree in IT), ride a longboard. All the time that I don’t spend with my family (a wife and a son) - I code, mostly hobby projects. I learned touch typing when I was studying at the university, by spray painting my keyboard. A comfortable typing speed for me is 220 characters per minute (Cyrillic and Latin keyboards).

I’m not actively searching for a new job at the moment, but I keep an eye open for interesting remote opportunities.

Here’s a list of my latest projects (both main job and hobby ones), with a short description of the project itself and my role in it.

Thank you for reading it all to the end :) It turned out to be rather long. Alexander.
