What I'm looking for

I seek senior roles building scalable cloud-native data platforms, applying AI/ML and real-time pipelines, with strong governance and collaborative, growth-focused teams.

I am a Lead Data Engineer and Data Architect with 10+ years designing and scaling cloud-native, AI-powered, analytics-ready data ecosystems across AWS, Azure, and GCP.

I have built Lakehouse and DataMesh platforms, real-time streaming pipelines, and integrated LLMs and vector databases to drive fraud detection, predictive models, and cost-optimized ML workflows, delivering measurable latency and training-time reductions.

I lead governance, compliance (HIPAA, GDPR, SOC2, PCI-DSS) and observability efforts, mentor engineering teams, and champion self-service BI and modern data stacks to accelerate enterprise digital transformation.
