What I'm looking for

I seek roles where I can build scalable, production-grade data and AI infrastructure, work with cloud-native tooling, and deliver measurable latency and reliability improvements.

I am a data engineer and AI infrastructure specialist with production experience designing scalable ELT pipelines and real-time AI-powered data systems.

I have built low-latency inference workflows and fault-tolerant streaming pipelines, provisioning cloud-native infrastructure on AWS and GCP and deploying reproducible environments with Terraform.

My hands-on projects include a RAG-based intelligence system on Google Cloud Run serving sub-300ms inference requests and a high-throughput crypto ingestion pipeline processing ~500,000 events per six-hour window, with anomaly detection latency under 3 seconds.

I focus on turning fragmented data into reliable, automated intelligence systems, implementing observability with Prometheus and Grafana, and delivering measurable improvements such as 50% reductions in data delivery latency and elimination of 20+ hours of manual reporting weekly.
