PROFESSIONAL EXPERIENCE
Java Developer | PrivatBank | Sep 2024 - May 2026 | Ukraine / Remote
 Developed and maintained Java/Spring Boot microservices for enterprise backend systems, focusing on REST APIs, service
integration, persistence, security, and production stability.
 Implemented Kafka/RabbitMQ-based asynchronous communication, including message publishing/consuming, error handling, and
service decoupling.
 Built transaction-aware persistence layers with Spring Data JPA, Hibernate, PostgreSQL/MySQL; optimized queries, indexes,
pagination, and Redis caching to reduce database load.
 Contributed to secure backend endpoints using Spring Security/JWT concepts, input validation, role-aware business logic,
exception handling, and reliable request processing.
 Worked through GitLab merge requests, code reviews, JUnit/Mockito testing, debugging, log analysis, and production issue
investigation.
Java Developer | DataMan | Mar 2023 - Aug 2024 | Ukraine / Remote
 Developed backend services for internal business applications and data-management systems using Java, Spring Boot, Spring
MVC, Spring Data JPA, Hibernate, and REST APIs.
 Designed JWT-secured REST endpoints for frontend-backend integration, DTO validation, structured responses, and consistent
error handling.
 Worked with Java EE, Servlet API, JDBC, and Tomcat to support server-side web components, database access, and deployment
workflows.
 Integrated PostgreSQL, MySQL, MongoDB, and Redis based on persistence, caching, and performance requirements.
 Improved maintainability by applying layered architecture, OOP/SOLID principles, reusable components, Git/GitLab workflows, Jira,
and code reviews.
Java Developer / Backend Projects | Mate Academy | Sep 2022 - Feb 2023 | Ukraine / Remote
 Built backend projects focused on REST APIs, authentication, persistence, validation, and maintainable layered architecture.
 Implemented business logic with Spring Boot, Hibernate/JPA, JDBC, SQL, Collections/Stream API, OOP/SOLID, and clean code
practices.
 Wrote JUnit/Mockito tests for service logic and optimized simple data-processing flows by reducing inefficient operations and
avoidable object creation.
KEY STRENGTHS
 Backend ownership: independent implementation of features from API contract and business logic to persistence, tests, review,
and release support.
 Database/performance mindset: transaction boundaries, indexes, SQL optimization, Redis caching, pagination, and JPA/Hibernate
tuning.
 Delivery maturity: GitLab merge requests, CI/CD workflows, code review culture, production troubleshooting, and remote Agile
collaboration.
