What I'm looking for

I seek backend roles focused on secure, scalable systems using Java/Spring Boot, collaborative Agile teams, opportunities to improve performance and observability, and clear paths for technical growth.

I am a Backend Developer with over 3 years building secure, high-performance server-side systems across fintech, CRM, and eCommerce domains. I specialize in Java and Spring Boot, delivering RESTful APIs, authentication systems, and payment gateway integrations.

I apply Test-Driven Development, Clean Architecture, and SOLID principles to improve reliability and maintainability, and I have experience optimizing performance, debugging production issues, and deploying services with Docker and CI/CD pipelines.

I collaborate well in Agile teams, document APIs with Swagger/Postman, and focus on compliance, security, and high availability to meet fintech-grade requirements.
