I will develop scalable, secure, and high performance backend applications using Java and Spring Boot. With more than four years of professional experience, I specialize in building RESTful APIs, microservices, and enterprise level backend systems that are reliable and production ready.

My expertise includes authentication and authorization using JWT and OAuth, database integration with MySQL, PostgreSQL, and MongoDB, and system optimization for better performance and scalability. I also work with tools like Docker, Redis, RabbitMQ, and AWS to ensure smooth deployments and efficient system communication.

When you work with me, you will receive clean, well structured, and maintainable code following best development practices. I focus strongly on security, performance optimization, proper documentation, and clear communication throughout the project lifecycle.

Whether you need to build a new backend from scratch, improve an existing system, integrate third party APIs, or design a scalable microservices architecture, I will deliver a solution tailored to your business requirements.

My goal is to provide production ready backend solutions that are stable, scalable, and built for long term success. Let’s work together to build a powerful and reliable backend system for your application.
