| Highlights: 1. Implementation of microservices architecture in four projects (automotive, logistics, public transport) including CI/CD pipelines and container deployment. 2. Migration of monolithic ERP system to REST services based on Spring – reducing the time to implement new features by 35%. 3. Creation of testing frameworks (JUnit, Mockito, FIT) and automated regression testing; reducing production errors by more than 40%. 4. Optimization of database access performance (Hibernate and stored procedures) – response times cut in half with more than 10,000 concurrent requests. 5. Training and mentoring of developers on clean code and best practices in Spring. |
