Open Source Evangelist, Back-end Architect, Systems Integrator and a Python Developer

With over 10 years of Information Technology (IT) development experience, I have demonstrated strengths in several activities, this includes, but not limited to, excelling and recording success in architecting and managing one of the largest databases in Africa (over 100 million voter records with biometrics​). I have also played a significant role in several other IT projects in government, education, and leading a team of developers in the development of an Electronic Medical Record (EMR) System used for HIV management in 94 primary, secondary, and tertiary facilities in south-eastern Nigeria. My industry expertise includes being a seasoned Django/Python/FastAPI Developer, Machine Learning and Computer Vision Implementer, Everything Data (BigData, ORDBMS, RDBMS, NoSQL) Advisor, and a Systems (Virtualization, HA, HCI, Cloud) Integrator.
