I will build Java Spring Boot microservices and REST API backend

I offer professional Java Spring Boot development services for businesses that need fast, secure, and scalable backend systems. With over 6 years of experience building fintech and SaaS platforms, I can help you with REST API development, microservices architecture, database design with PostgreSQL or MySQL, payment gateway integrations, JWT authentication and role-based access control, Apache Kafka event-driven systems, and Redis caching for high performance.
I've built production systems, including a fintech platform with 21 microservices processing 5M+ daily messages, PCI-DSS compliant card payment integrations, and report generation systems handling 500,000+ rows of data. Whether you need a new backend built from scratch, an existing Spring Boot application improved or debugged, a third-party API integrated securely, or a monolith migrated to microservices — I deliver clean, well-documented, production-grade code.
What you get when you work with me: honest communication, realistic timelines, maintainable code following best practices, and support after delivery. Message me with your project details, and I'll get back to you within a few hours with a clear plan.
