What I'm looking for

I'm looking to design and improve cloud data architectures, models, pipelines, governance, and quality practices while solving complex data challenges and supporting teams with practical technical guidance.

At DataSeal Kenya, I design data warehouse, data lake, and data vault architectures across Snowflake, AWS Redshift, Azure, Databricks, Teradata, and GCP platforms.

I translate business needs into conceptual, logical, and physical data models, data marts, warehouses, and vaults. I build ETL and ELT pipelines with SSIS, Azure Data Factory, Matillion, and Snowflake Tasks while improving data quality, reducing redundancy, and supporting database performance.

My work includes reverse-engineering legacy systems, mapping on-premise databases to cloud platforms, documenting source-to-target flows, and defining data architecture standards. I also work with governance and quality teams on reference data, master data, metadata, cleansing rules, and regulatory compliance.

Earlier, I supported ERP customers, developed backend solutions in .NET, C#, and SQL, customized Acumatica, and built API-driven application integrations. I bring over five years of experience across data architecture, data modeling, analysis, security, and cloud data platforms.
