What I'm looking for

I’m seeking remote international opportunities as a Java Backend Developer, focused on backend execution, system reliability, and scalable cloud-based solutions—building dependable services with clear APIs and fault-tolerant integrations.

I’m a Java Backend Developer with over 6 years of experience building Java-based backend systems in production environments, with a strong foundation in enterprise and financial software development. I focus on backend logic, data processing, and system reliability, evolving toward scalable and maintainable services.

Currently, as an Individual Contributor, I develop and maintain core order management systems, achieving 99.9% uptime across critical P0/P1 availability requirements. I’ve built backend microservices using Java 21 and .NET, integrated REST APIs with AWS SNS and AWS SQS for asynchronous communication, and architected recalculation engines that significantly reduce pricing errors. I also run CI/CD pipelines and improve deployment reliability, including a 25% decrease in failure rates during deployments.

Previously, I delivered critical Java 21 microservices for financial and payment systems, including an ABECS file-processing microservice that enabled automatic MCC updates and eliminated client fines, generating savings of millions in penalties. I’ve also supported migration from legacy to cloud-based architectures and contributed to frontend features using React.js when required, bringing a practical, fail-safe mindset to both reliability and performance.
