I’m a Java Full Stack Engineer with 3+ years of experience building production-grade REST APIs, microservices, and cloud-ready systems. I focus on scalable application design, performance optimization, and reliability in real production environments.

At Allianz Technology, I developed and maintained multiple REST APIs using Java and Spring Boot, improving API performance by ~30% through query optimization and reducing unnecessary DB calls. I automated CI/CD pipelines with Jenkins, cutting deployment time by ~60%, and containerized services with Docker and Kubernetes for smoother releases and operations.

I also strengthened platform security and system robustness by implementing Spring Security with JWT-based authentication and role-based authorization across microservices, integrating Kafka for asynchronous communication, and adding monitoring with Prometheus and Grafana. I’m motivated by roles where I can design fault-tolerant microservices, standardize API contracts, and continuously improve quality (including raising automated test coverage to 90%).
