What I'm looking for

I’m looking to lead end-to-end data ingestion and ETL-to-API platforms in cloud-native environments, partnering with ML and product teams, and owning secure, reliable delivery with Docker/Kubernetes, AWS, and strong CI/CD practices.

I’m a Senior Systems Engineer with ~13 years building ETL systems, APIs, and cloud-native applications using Java and Python. I lead technical designs and deliver reliable, secure data-processing solutions by combining batch and near-real-time ingestion with RESTful service APIs.

In my recent work, I architected message-driven ingestion with RabbitMQ, containerized services with Docker, and deployed on Kubernetes in AWS. I also partner with data scientists and ML engineers to design data contracts and schema-on-read views, while applying OWASP guidance and coordinating CVE remediation through CI/CD pipelines.
