I’m a senior Java backend developer with 16 years of experience, specializing in Java, Spring Boot, and Maven. I focus on backend architecture, modularization, and the modernization of legacy systems - delivering clear, maintainable, and production-ready code. I’ve built and maintained systems in banking, trading, and internal enterprise tools. I’m particularly experienced in cleaning up large, outdated codebases: refactoring, extracting modules, and introducing structure where it’s lacking. Beyond Java, Spring, and Maven, I regularly work with: - Persistence & Databases: Hibernate, Blaze-Persistence, Liquibase, Flyway, SQL (PostgreSQL, H2) - Web & Integration: JSF, PrimeFaces, REST APIs, gRPC, Protocol Buffers - Testing: JUnit, Mockito, PowerMock, Testcontainers - Build & DevOps: Jenkins, Docker, Git - Reporting & Documentation: JasperReports, PlantUML Whether you need to break a monolith into modules, modernize a legacy system, or get a chaotic project back under control, I deliver practical solutions without overengineering. I work independently, communicate clearly, and build solid software that lasts. My spoken English is limited. I prefer written communication. Please expect text-first collaboration; I can join brief voice calls for kickoffs or clarifications.

I am interested in: - Cordova Plugin development - Capacitor Plugin development - Hybrid app development (React Native/Ionic/Cordova) - React JS development - AWS, Firebase, - API development - Android native app development - iOs native app development(Objective-C/C++) - Integrating/migrating your legacy (C/C++) lib to Android (JNI, NDK) - ME(R/A)N(Mongo/Express/React Native/Angular/Node) projects Whether it is a project of 15+ or of a single developer you can count on my 15+ years of experience in the mobile/embedded industry, ps: I am sorry that I haven't taken any tests, but having sites with all the solutions for the tests makes them quite difficult to rely on.
