Я разрабатываю Java backend-сервисы с Spring Boot, PostgreSQL и Docker.

Russian Federation

Я разрабатывал backend-сервисы на Java и Spring Boot для AdaptixBot, включая серверную логику Telegram-бота, обработку данных и управление состоянием приложения.

В коммерческом проекте Parser Rubli Reviews самостоятельно создал и развивал многопоточный Java-парсер для автоматизированного сбора, обработки и подготовки отзывов. Оптимизировал параллельную обработку и архитектуру приложения.

Для StockForecasting разработал Java-приложение для обработки и прогнозирования биржевых данных, спроектировал реляционную модель PostgreSQL и подготовил ERD и IDEF1X-схемы. Работаю с SQL, Redis, Docker, Gradle, асинхронной обработкой и мониторингом сервисов.
