What I'm looking for

I’m looking for a Java backend role where I can build Kafka-based microservices for high-volume banking workflows, improve performance with SQL, own integrations, and deliver reliable, test-covered systems and reports.

I’m a Java Developer with 2 years of experience building backend solutions for banking and financial systems. I develop scalable microservices with Java and Spring Boot, and I design Kafka-based asynchronous pipelines for high-volume transaction processing.

I strengthen reliability and performance by optimizing complex Oracle SQL queries across datasets with tens of millions of records, writing unit tests with JUnit, and resolving production issues and security vulnerabilities. I also deliver regulated workflows using scheduled batch jobs for reconciliation, secure file handling with AWS S3/SFTP, and report generation with JasperReports.
