What I'm looking for

I’m seeking a Java/backend role focused on building scalable microservices and secure payment systems within an Agile, collaborative team that values clean code and continuous learning.

I am a Java developer with hands-on experience building Spring Boot microservices and secure payment systems.

During a Java Developer Trainee role I contributed to a Stripe Payment Integration project, implementing modular payment-processing and stripe-provider services, security mechanisms (Stripe Basic Auth, HmacSHA256), payment status tracking, and robust error handling.

I have practical experience with RESTful APIs, MySQL (Spring JDBC), ActiveMQ for asynchronous messaging, and AWS services such as EC2, RDS, and Secrets Manager, and I explored Spring AI with OpenAI LLM for dynamic error handling.

I write modular, production-ready code, apply design patterns (Factory, Builder), follow Agile/Scrum practices, and seek a Java/Backend Developer role where I can contribute to scalable systems and continue growing my backend and cloud skills.
