My name is Boris, and I am a Java backend engineer. This is my GitHub profile, where you can find my Java projects and code. I specialize in Java, Spring, SQL, and containerization, focusing on building scalable, high-performance containerized microservices.

FinTech Web Application

• Developed CSV import microservice with an event-driven architecture, integrating it with existing microservices and implementing Kafka for reliable messaging
• Designed the PostgreSQL database schema and a flexible CSV template structure (predefined, auto-generated, AI-assisted), enabling faster template creation and efficient CSV content parsing and import
• Ensured containerization with Docker, performed code reviews improved Mailing microservice for better notifications, and implemented Elasticsearch indexing for emails and attachments to enhance search and retrieval

Digital Asset Management Platform

• Designed and implemented the IPim Validator for metadata and digital asset validation
• Improvements in code coverage and standardized testing practices across the platform
• Collaborated with Angular frontend developers and QA to ensure Date&Time field consistency, improving overall system reliability

Cloud-Based Construction Reporting Tool

• Developed and integrated features for report exporting, emailing, and cloud storage within a microservices architecture
• Leveraged AWS S3 for secure and scalable storage of daily construction reports
• Contributed to bug fixes and overall system stability during the development lifecycle
• Resulted in a more efficient, automated process for generating and sharing field reports

Warehouse & Sales Management System

• Maintained and enhanced the warehouse information system by developing REST endpoints (Java, Spring Boot, Hibernate), fixing bugs, and optimizing queries against AWS RDS databases
• Assisted in transitioning backend services from GraphQL to REST and contributed to event-driven features with Apache Kafka for near real-time stock synchronization across warehouses
• Improved reliability and delivery by writing unit/integration tests and supporting deployments with Docker, GitLab CI/CD
