Experience

  • Data Engineer @Moniepoint

    August 2025 - till date | London, UK

    As a data engineer, I quickly added value by authoring a comprehensive technical and business guide for the loan data engineering team within my first two weeks. This documentation streamlined environment setup, accelerated onboarding for new team members, and enhanced understanding of end-to-end business workflows.      I also optimized a critical long-running Airflow workflow by restructuring its logic, improving task dependencies, and eliminating unnecessary bottlenecks. These improvements reduced execution time from several days to under one hour, significantly accelerating reporting cycles and boosting overall system performance.

  • Data Engineer @VFD Tech Limited (Contracted to VFD Microfinance Bank)

    Apr 2023 - August 2025 | Lekki, NG

    As 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.

Education

  • Bachelor of Science in Computer Science

    2019-2023 | University Of Nigeria, Nsukka (UNN)

    Relevant courses included Data Structures and Algorithms, Computer Systems Engineering, and Artificial Intelligence.
