NigeriaWhat I'm looking for
I am a Senior Data Engineer with over 10 years of experience in architecting scalable data solutions across both on-prem and cloud environments. My journey has been marked by a proven expertise in MPP databases, SQL performance tuning, and distributed computing with Spark. At Rightship in Malta, I designed and led the end-to-end architecture for scalable ETL pipelines using Azure Databricks and Delta Lake, processing millions of shipping data records daily. My work has consistently focused on transforming complex requirements into performant pipelines, ensuring high reliability and data quality.
Throughout my career, I have developed and optimized complex SQL workloads involving CTEs, window functions, and partitioned joins across terabyte-scale datasets. I have also engineered robust ETL frameworks using Python and Spark on Azure cloud for farmer-level data processing across East Africa during my tenure at One Acre Fund. My leadership extends to mentoring junior developers and introducing a data quality validation layer that significantly reduced pipeline errors by 40%. I am passionate about leveraging my skills to drive impactful data initiatives and contribute to organizational success.
