Project details

will build secure, scalable, and production-ready backend systems using Java Spring Boot and REST APIs for web and business applications.

This service is designed for startups, businesses, and teams that need clean backend architecture, reliable APIs, and long-term maintainability. I focus on writing well-structured code, implementing secure authentication (JWT & role-based access), and ensuring smooth database integration.

Whether you need a single API endpoint, full CRUD operations, or a complete backend system, I follow best practices for performance, security, and scalability. My approach includes clear requirement analysis, structured API design, proper validation, and thorough testing.

You will receive clean source code, clear communication throughout the project, and predictable delivery aligned with the selected package. I treat every project as a production system, not a quick demo, ensuring the backend is easy to extend and maintain in the future.

Communication Styles survey functionality This was my first time using Upwork and Soniya not only sheparded me through the process, she was technically competent, professional and able to refine the project as I updated details not originally in the scope. I highly recommend her and will reach out to her again!

"Enterprise-grade Java systems. Delivered on time."
I've built and maintained production microservices at Optum (UnitedHealth Group) — platforms serving millions of users. Now I bring that same reliability to freelance clients who need backend systems done right the first time.
What I work with: Java · Spring Boot · REST APIs · React.js · MySQL · Microservices
Whether you need a new API built from scratch, a bug squashed in production, or a full-stack feature delivered — I can turn it around fast and clean. Open to both fixed-price and hourly. Let's talk.

Backend Development & API Implementation

I develop secure and scalable REST APIs using Java Spring Boot, including business logic, database integration, and authentication where required.
