About this gig

You will get a legacy Java application modernized toward a scalable microservices architecture, with a focus on clean service boundaries, maintainability, performance, security, and production readiness.


With 6+ years of Java and Spring development experience, I specialize in Legacy Java Modernization, Spring Boot, Microservices, REST APIs, Hibernate/JPA, database integration, and backend performance optimization.


I can assess your existing application, identify suitable components for migration, refactor legacy code, develop independent Spring Boot microservices, design REST APIs, integrate databases, and maintain existing business functionality during the modernization process.


My experience includes working on enterprise applications, complex backend systems, financial software, and multi-service architectures, including an IFRS 9 Credit Risk Analytics platform built with Java, Spring Boot, and MySQL.


Whether you are moving from a legacy Java application or monolithic architecture to microservices, I will focus on a practical and controlled modernization approach that improves maintainability and scalability while minimizing disruption to your existing system
