What I'm looking for

I seek a senior data-platform role building secure, scalable Lakehouse and streaming solutions in a collaborative, product-focused team that values reliability, cost optimization, and enabling analytics/ML.

I am a hands-on Senior Data Engineer and Data Architect with 10+ years designing, building, and owning large-scale cloud-native data platforms across healthcare, SaaS, analytics, and regulated industries. I deliver Lakehouse and data warehouse architectures, high-volume ETL/ELT and streaming pipelines, and enable analytics, BI, and AI/ML workflows while mentoring engineers and collaborating with product and business stakeholders.

I have led multi-cloud implementations using Databricks, Spark, Snowflake, AWS, Azure, and GCP, implemented CDC and real-time ingestion, applied DataVault2.0 and dimensional modeling, and drove cost optimization, data reliability, security, and governance practices. I consistently own end-to-end deployment, monitoring, performance tuning, and infrastructure-as-code for scalable, compliant data platforms.
