What I'm looking for

I seek roles where I can design and operate scalable, well-governed data platforms, lead cloud migrations, automate infrastructure and pipelines, and improve observability and reliability within collaborative, engineering-driven teams.

I am a Lead Data Engineer with 10 years of experience building end-to-end data solutions across on-prem and cloud environments. I design scalable pipelines, data models, and cloud infrastructure while emphasizing automation, observability, and cost efficiency.

I have led migrations to cloud platforms, implemented IaC with Terraform, and managed ELT with dbt and orchestration with Airflow, improving uptime, performance, and reducing manual effort. My work spans data ingestion, transformation, modeling, orchestration, data quality, and governance for analytics, BI, and data science.

I focus on delivering reliable, documented, and testable data platforms, driving improvements in operational response and stakeholder automation—eliminating manual processes and stabilizing production systems.
