About this gig

You will get a modernized, production-ready Java application with a cleaner, more maintainable architecture and Spring Boot modernization where appropriate .


With 6+ years of Java and Spring development experience , I specialize in improving existing Java applications while keeping business logic, functionality, security, and production stability in focus.


I can help modernize legacy Java applications, upgrade outdated frameworks, refactor backend code, improve API and database performance, resolve technical issues, and move suitable components toward modern Spring Boot and microservice architectures.


My experience includes working on enterprise applications, complex backend systems, REST APIs, financial software, and large business applications, including an IFRS 9 Credit Risk Analytics platform built with Java, Spring Boot, and MySQL.


Whether you need legacy Java modernization, Spring Boot migration, backend refactoring, performance optimization, or gradual migration toward microservices, I focus on a safe and practical implementation that improves your application without unnecessary disruption to existing functionality.
