What I'm looking for

I seek senior roles building cloud-native data platforms and streaming systems where I can lead architecture, mentor teams, and improve reliability, performance, and compliance.

I am a Senior Data Engineer and Cloud Data Architect with 9+ years building scalable, secure, production-grade data platforms across healthcare, finance, and enterprise SaaS.

I design and operate cloud-native lakehouse architectures (Delta Lake, Iceberg, Hudi) and build large-scale ETL/ELT pipelines using dbt and Spark, as well as real-time streaming systems with Kafka, Flink, Spark Streaming, and Kinesis to support analytics, ML, and AI-driven pipelines.

I have led cloud migrations, platform modernization, and data mesh adoption in regulated environments, improving reliability, reducing data latency by 50%, cutting runtimes by 45%, and maintaining 99.9% SLA reliability while reducing incidents and costs through observability and governance.

I partner closely with product, analytics, and ML teams, provide hands-on technical leadership and mentorship, and implement DevOps, security, and cost-optimization practices to deliver trusted, timely, and compliant data solutions.
