Ali Usman

I'm a Java Backend Engineer with 3+ years of professional experience developing enterprise-grade backend applications using Java, Spring Boot, Hibernate, JPA, PostgreSQL, MySQL, REST APIs, and Microservices. I specialize in designing scalable backend systems, optimizing SQL performance, integrating third-party services, implementing secure authentication with Spring Security and JWT, and maintaining production applications on Linux. I have hands-on experience with production deployments, troubleshooting, batch processing, scheduled jobs, and performance optimization. I enjoy solving complex technical problems, writing clean and maintainable code, and collaborating with remote teams to build reliable, high-performance software. I'm currently looking for remote Java Backend Engineer opportunities where I can contribute to scalable enterprise systems while continuing to grow as a backend engineer.
