You will get Add or improve a Java Spring Boot feature
Project details
I will add or improve one clearly defined feature in an existing Java Spring Boot application.
This can include a new back-end action, a feature improvement, a filter/search option, an export/download action, a business rule adjustment, or a connection between an existing UI flow and Spring Boot back-end logic.
I focus on practical business application work: clear scope, readable code, safe changes, and a short summary of what was changed. This project is best for defined feature work in an existing application, not for building a full new system or large multi-screen module from scratch.

I can help with both existing Java/Spring Boot systems and new development work, including APIs, integrations, business logic, database-backed features, internal tools, and full-stack features when needed.
* Java, Spring Boot, APIs, integrations, SQL databases, Git, Docker, and front-end work when needed
* Experience with business applications, back-end services, database work, internal workflows, and practical feature development
* Can help build new features, improve existing applications, fix bugs, refactor code, clean up APIs, and support legacy Java/Spring systems
* Full-stack experience when needed, including Angular, but my main focus is Java/Spring back-end work
* Available for defined tasks, ongoing hourly work, and longer-term support
* I work best with clear written communication, task descriptions, and regular async updates
