I worked on a URL checker service that parses URLs, handles redirects, user data, and notifications. Migrated the system from PHP 7.4 to 8.3, Symfony 5.6 to 7.1, and updated MySQL Percona. Refactored legacy code using modern patterns, optimized old and new RESTful APIs, replaced constants with enums, and automated migration from annotations to attributes with Rector. Integrated services like VirusTotal, AdSec, AdBlock, YandexSafeBrowsing, and others.

I contributed to three major projects across frontend and backend: Built scalable microservices for crypto operations and trading developed a secure authorization module with 2FA and RBAC and created a communication layer using RabbitMQ for reliable service interaction. Developed frontend with React/Vue.js, backend with Node.js/Laravel and integrated Zoom API for virtual consultations. Delivered responsive UI, secure transaction handling, and integrated banking systems for streamlined financial operations.

At TCO Team, I built a time tracking system using Laravel, React.js, and MySQL. Developed backend features like user management and reporting, and created an admin panel in React. Integrated with a Python microservice for real-time check-in/out via hardware. Built a notification system using Telegram bots and WebSocket. Ensured seamless integration across all components for reliable, high-performance operation.

I developed and optimized e-commerce platforms, focusing on product management, orders, and user experience. Used Laravel, Symfony, React, Vue.js, MySQL, and PostgreSQL to build scalable APIs and dynamic UIs. Optimized EAV models and SQL queries, improved database performance, and enhanced system scalability to ensure fast, reliable, and efficient operations.
