At Polestar Global, I build and own distributed backend integration services for real-time maritime intelligence, processing continuous global ship-position streams with Java, Spring Boot, Apache Kafka, PostgreSQL, Redis, and AWS.
I architected a high-throughput ship-position platform managing more than 16 TB of historical and live geospatial data, achieving sub-50 ms query latency through PostgreSQL partitioning, indexing, and query optimization.
I also built an AI-powered support automation and document-processing platform using Amazon Bedrock, Textract, Step Functions, Lambda, and DynamoDB. It automates 350–450 monthly support and document-extraction cases and reduced average resolution time by 83%.
I deliver secure, fault-tolerant microservices and RESTful/SOAP integrations with OAuth 2.0, JWT, IAM, Terraform, CloudFormation, Docker, Kubernetes, CloudWatch, and X-Ray.
