About Andriy
PHP | Yii2 Backend Developer | Custom Web Services & REST API
Kyiv, Ukraine - 8:27 am local time
Hi, friends! My name is Andriy. I am a Strong Middle Backend Developer with strong experience in PHP and Yii2.
💼 What I Do:
☑️ Developing web services (Telegram chatbots, parsers, comparison systems, management systems).
☑️ Building and enhancing websites: landing pages, corporate websites, online stores, blogs, and portals.
☑️ Designing and implementing REST APIs from scratch.
☑️ Integrating with various third-party APIs, including payment gateways and data exchange systems.
⚙️ Tech Stack:
1) PHP & Yii2
My primary stack. I work extensively with Yii2, using it to build complex web services, APIs, admin systems, and ecommerce platforms.
PHP is my main programming language — I follow clean architecture, OOP, and SOLID principles.
I also have light experience with WordPress — minor plugin tweaks, custom feature adjustments, and client-requested modifications when needed.
2) HTML, CSS, JS, jQuery, Bootstrap
I can handle frontend integration tasks: fix layouts, adjust CSS, modify components, or connect forms and data with backend logic.
I don’t create designs from scratch, but I can easily maintain and enhance existing UI tied to backend functionality.
3) MySQL
Daily work with relational databases — from schema design and query optimization to migrations and data structuring.
I ensure clean, consistent database logic and optimized queries in every project.
🧰Tools & Services:
Composer, Redis, Git (GitHub / GitLab / Bitbucket), Postman, Docker, REST API testing tools, basic Linux server setup.
