About

Professional summary

I am a PHP developer with experience building and supporting web applications, backend systems, and e-commerce functionality. I have worked on import modules, payment integrations, administrative panels, and PDF catalog generation with QR codes.

I most recently worked on a high-load backend project where I developed secure product review functionality, built APIs for data exchange with multiple services, and optimized Magento modules. I also contributed to frontend improvements using ReactJS.

Earlier, I worked for SANDI+ trading company, where I developed and supported import modules for partner websites and created a web application for displaying and playing back IP telephony calls from call centers.

My technical background includes PHP, JavaScript, Laravel, Yii2, CodeIgniter, Vue.js, Magento, ReactJS, MySQL, PostgreSQL, GraphQL, Redis, RabbitMQ, Varnish, and API integrations. I also use tools such as Git, Docker, Vagrant, and OpenServer.

I have experience working with CMS platforms such as OpenCart and Okay CMS, and I am comfortable developing both backend and frontend features when needed.

I am based in Kharkov and speak Russian natively and English at an intermediate level. I am looking for opportunities where I can continue developing scalable web applications and backend solutions.
