Zain Sarwar

At Sayeon, I lead the design and delivery of scalable data pipelines, ETL/ELT workflows, and cloud data platforms for enterprise analytics, reporting, and operational requirements.

I build production data solutions with Python, SQL, PySpark, Apache Spark, Azure Data Factory, Databricks, Snowflake, and dbt. My work includes Lakehouse and dimensional models, governed datasets, automated validation, monitoring, and performance optimization.

Previously at Tier1 IT and Redtech, I developed enterprise ETL pipelines, SSIS packages, SQL transformations, Power BI dashboards, analytical datasets, and reporting data models. I’ve integrated APIs, databases, cloud storage, CRM platforms, and third-party systems into reliable centralized data environments.

I also lead cloud modernization efforts, establish Git-based CI/CD and deployment practices, and work closely with analysts, data scientists, BI teams, engineers, and business stakeholders to turn requirements into dependable data products.
