What I'm looking for

I am seeking a senior data modelling/architecture/engineering/SQL role where I can design cloud data platforms, lead migrations, enforce governance and improve data processing efficiency.

I am a hands-on Data Architect and Data Engineer with deep experience designing and implementing data warehouses, data lakes, and ETL pipelines across cloud and on-prem platforms. I have led data modeling, migration and governance efforts while applying best practices for security, availability and performance.

I have delivered measurable results including a 20% improvement in data processing efficiency by building scalable data solutions and automating data load and lineage processes using Python, SQL and orchestration tools. I design logical and physical data models with Erwin/IBM tools and implement solutions in Snowflake, Azure, and other RDBMS environments.

I seek to apply my experience in data modeling, data migration to cloud platforms, master data management and analytics enablement to help organizations turn disparate systems into reliable, governed data assets. I prioritize clear documentation, naming standards, data quality and collaboration with stakeholders.
