I build scalable backend microservices, data pipelines, and serverless systems using Java, Python, AWS, and ELK.

I'm building serverless backend systems at The Grid Solutions, using FastAPI, AWS Lambda, API Gateway, EventBridge, SQS, SNS, and PostgreSQL on AWS RDS to ingest, transform, analyze, and distribute client data.

Previously at Persistent Systems, I developed Spring Boot microservices and real-time data pipelines for a SIEM platform. I transformed multi-source logs for dashboard integration, improved performance with PostgreSQL and Redis, and supported large-scale ingestion with Elasticsearch, Logstash, Kibana, Docker, and JUnit.

I've been recognized with two Bravo team awards and a high-five award, and I bring a clean-architecture, reliability-focused approach to backend engineering.
