Full Stack Java/Angular

Senior full stack developer.English fluent (B2+).Strong production experience with Java 21 and Spring Boot 3.x (REST, JPA/Hibernate, Spring Security, transactions, async/virtual threads).Solid Angular 21 experience, or demonstrated ability to adopt Angular’s latest patterns: signals, new control flow, standalone-first architecture.Hands-on experience with PostgreSQL (schema design, Flyway migrations, query optimization) and MongoDB (document modeling, aggregations, Spring Data).Comfort working with XML-heavy systems: XSD schemas, XSLT, parsers, or metadata-driven logic; experience with custom DSLs or rule engines is a strong plus.Familiarity with Redis for caching and session state.Understanding of hexagonal / clean architecture and domain-driven design in multi-module Maven projects.Experience with GitHub Actions or similar CI/CD, SonarQube quality gates, and container-based workflows (Docker, Kubernetes/Helm).Strong testing discipline: JUnit 5, Testcontainers, and ideally BDD (Cucumber/Gherkin, Playwright).Fluent with Git, code review culture, and agile delivery.Requested task to perform: Build and enhance frontend features in Angular 21 (signals, standalone components, new control flow syntax, RxJS, state management, ngx-ndbx/ng-aquila component libraris).Work with and extend the proprietary PEL-PC XML DSL - including XSD schemas, ANTLR grammar logic, XSLT/Saxon transformations, and XStream serialization.Develop new Spring Boot modules that replace DSL-driven logic with maintainable, testable standard code#J-*****-Ljbffr
