Biography

I'm a senior Flutter and mobile developer with over 4 years of hands-on experience building production-grade, offline-first applications. Based in Accra, Ghana, I specialize in spatial data collection, clean architecture, and field-ready mobile solutions. I have built and shipped apps to the Google Play Store and I work with clients and businesses across Africa and beyond to turn complex problems into simple, reliable software.

Experience

  • Afarinick Company Limited
    ( 2024 — Present )

    Mobile App Developer

    Developed and maintained production Flutter mobile applications that collect spatial data — including GPS points and multipolygon farm boundaries — from remote field locations and sync them to the cloud for geospatial analysis. Implemented offline-first architecture to ensure full functionality in areas with limited connectivity.

    Additionally built backend services in Python/Django and Golang to support cloud-based manipulation, storage, and analysis of spatial datasets. Two apps built at Afarinick are live on the Google Play Store with active users.

Education

  • Kwame Nkrumah University of Science and Technology
    ( 2020 — 2022 )

    Computer Science

    Gained proficiency in Python, Dart, C/C++, Java, Visual Basic, and Assembly Language. Developed a strong foundation in software development methodologies including Agile and Scrum, which continue to shape my approach to building reliable, maintainable software.

  • Achimota School
    ( 2017 — 2020 )

    Agricultural Science

    Built strong foundations in analytical thinking, leadership, and teamwork. These experiences developed my ability to collaborate effectively in diverse, fast-paced environments — skills that translate directly into how I work with clients and development teams today.
