What I'm looking for

Seeking a remote Java Developer role to build scalable Spring Boot microservices , high-throughput APIs, and Angular interfaces

I’m a Java Developer with 5 years of experience building scalable enterprise applications using Java, Spring Boot, microservices, REST APIs, and Kafka. I focus on clean system design, secure implementations with Spring Security, and reliable integrations that help internal teams ship faster.

At OSTTRA, I architected and built a centralized Data Extraction Microservice from the ground up for multi-tenant enterprise use. I developed Spring Boot REST APIs, integrated AWS S3 for secure report storage, and implemented efficient batch processing with PostgreSQL-backed persistence.

At Netcracker, I delivered both backend and frontend capabilities for the CCI platform using Spring Boot and Angular 17. I reduced API response time by 40% through caching, database query optimization, and asynchronous processing, while increasing unit test coverage from 55% to 75% with JUnit, Mockito, and JaCoCo. I also contributed to Kubernetes-based CI/CD pipelines, cutting deployment time by 60%.

I’m especially energized by GenAI-enabled production work. I built an AI-powered Production Support Assistant with Spring AI, Kafka, and PostgreSQL, using RAG with PgVector for semantic incident support and implementing workflows for incident summarization and root-cause identification.
