Data Engineer @VFD TECH
Apr 2023 - till date | Lekki, NGAs a data engineer, I significantly enhanced operational efficiency by refactoring production code to leverage Spark for big data processing, reducing processing time from 3 hours to just 15 minutes. I developed a containerized Streamlit application that empowered cross-functional teams to independently access needed data, decreasing reliance on the data team by 40%. I established robust documentation practices using Confluence to ensure continuity of knowledge across all data workflows and system configurations. Working closely with Finance, Product, and Audit teams, I delivered scalable data solutions utilizing Databricks, Azure Blob Storage, and Redshift. Throughout these initiatives, I maintained data integrity by implementing comprehensive validation processes that verified destination database accuracy against source data.
Data Engineer Trainee @Core Data Engineer
Aug 2024 - Oct 2024 | Berlin, Germany.I implemented robust data orchestration solutions leveraging AWS cloud infrastructure and Docker containers, creating scalable and reproducible data engineering environments. By designing sophisticated data modeling and transformation strategies with DBT, I developed modular and maintainable data pipeline architectures that significantly enhanced both team productivity and data reliability. Additionally, I created comprehensive documentation for data operations procedures and system configurations, facilitating seamless knowledge transfer and operational continuity across teams.
Data Engineer Consultant @Blaitware
Oct 2023 - Dec 2023 | FCT, Abuja.I built and deployed ETL pipelines that reduced data processing time by 40%, enabling faster client reporting. I also collaborated with the software engineering team to integrate backend APIs with data pipelines, ensuring real-time data synchronization. Additionally, I optimized database schema and indexing strategies, significantly improving query performance for analytics use cases.
Data Engineer Instructor @Roar Nigeria
Mar 2022 - Oct 2023 | UNN, Nsukka.I trained over 200 students in foundational data engineering concepts such as data pipelines, ETL, and cloud tools through an intensive university-based technical program. I delivered hands-on sessions on building and querying relational databases using real-world datasets and guided trainees through structured projects to apply their knowledge and develop portfolio-ready work.
Data Engineer(Freelance) @Upwork
Jan 2021 - Dec 2022 | California, US.I partnered with a fintech startup to architect and deploy a scalable data pipeline utilizing Apache Kafka and AWS Cloud Services, enabling real-time financial data processing and analysis. For a healthcare client, I engineered a comprehensive data integration solution using Python and Apache Spark that successfully consolidated disparate data sources, substantially improving data accessibility and decision-making capabilities. Additionally, I developed customized ETL workflows for an e-commerce platform by leveraging Airflow and Redshift, which streamlined data transformation processes and delivered actionable business intelligence insights that drove strategic decision-making.
