Hello,
my name is Sergei Iamskoi and this is my resume/cv

About Me

PHP is my main development language. I consider myself to be a backend developer mainly. Although I also have frontend development experience (AngularJS, jQuery). Also I’m familiar with Java, C#.
I study and use C ++ as a hobby.
I have experience in designing a system architecture from scratch and in designing individual components, as well as further their implementation. Experience in design and implementation services. Experience in developing Uber-like systems in the b2b sector.
I take an active part in the discussion of decisions, I can explain and defend my point of view and be responsible for the decision.
I know the full cycle of work with tasks from the discussion of the idea to its realization (transferring it to analysts, decomposition, evaluation).
When writing code, I practice OOP and use design patterns as needed (I read the book «Gang of four Design patterns»). I try to follow best practices like SOLID/KISS/DRY and strive for the beauty of a code.

  • Huge experience with PHP framework Yii 2.0
  • Good understanding MVC
  • Web Application Life Cycle
  • Knowledge of how web applications and servers work
  • Knowledge of Postgresql, MySQL at the database design level, writing complex queries, query optimization. Work with transactions.
  • I know Javascript: language itself and libraries / frameworks
  • I did a couple of projects in Angular
  • Using Redmine, Jira as bug / issue tracker.

I am constantly improving as a developer. I try to develop not only in known stack of technologies, but also in related. I work freely in Windows, Linux (Ubuntu / Debian), MacOS (preferred). Extensive experience with the console, setting up the local environment and interacting with remote servers via SSH, server configuration: debian, nginx, php-fpm, deploying a DBMS, setting up a mail server, monitoring, setting up system security. Quickly learn new technologies, usually by myself by documentation. I like to program, discuss and solve complex problems. To create a truly useful and necessary services for society.

My hobbies are related to IT and development. I am fond of circuit design, microcontrollers, learning different languages and technologies. Also I like to ride a bike, to read Habr. I love nature.

What I'm looking for I want to find a professional web / mobile development team. A team that loves its job and does it well. And where a entire development process is adjusted.

Or I will gladly join to a company that needs my help in organizing this development process and creating a strong development team. If this is a cool interesting startup - then write too!
