Great professional growth with my latest work. 

I managed to optimize the calculation of some functions while working on my latest project. One such optimization was tough and required deep investigation and extremely accurate implementation for its complex logic and wide relationships with other components. 

Also, I successfully realized a report generation script for a very critical customer with a complex requirements list and database structure in a short period.
From newest to oldest.
My latest project was the development of a multifunctional candidate evaluation system. It's an international high-load system with high accuracy and stability requirements. The data structure of the project is very complex, its database is enormous, and it's built using Plain PHP. So, the maintenance of this project wasn't easy. For this project, I was:
- developing new features and refactoring the old ones;
- optimizing database requests and process execution;
- integrating with third-party API;
- researching problematic issues with produced results;
- performing hotfixes;
- deploying on production;
- using PostgreSQL, PHP 7, RabbitMQ, Redis, Nginx

Before.
My work experience with Yii/Yii2 frameworks.
I tried myself as a full-stack developer while working alone on two projects in parallel. One of them was a kind of office CMS, and another was a site that provided some tourist services. Both of them were almost at the startup stage. I was glad to learn new skills: Yii frameworks, Bootstrap, Ajax, and jQuery. Also, I've tried to implement integration with some public APIs (PayPal, uLogin).

Before.
My work for a real estate project.
I developed an import/export system for realty announcements. In detail, this system gathers/publicizes realty estate object data from/to the websites, parses it, determines its GPS coordinates using third-party API, and stores all of it in a database. My scripts perform all of these tasks automatically, and they are integrated into Rieltor CMS. I used PHP 5, and MySQL for this project development

In the beginning.
I developed 3 e-shop sites and one of them includes self-written CMS. Work alone with the trial-and-error method. I was studying several skills simultaneously: PHP, Javascript, CSS, HTML, and MySql.
I always tend toward professional growth. I want to practice new skills: Symfony, Docker, Microservices, and maybe others. I like to deal with complex tasks in web development and not only.
