I'm Dr. Osasenaga David Evbayiro, a veterinary doctor, software engineer, researcher and founder of $E-Network, based in Nigeria. My work spans clinical software, election systems, commerce and tools for research.
I work across product architecture, Python backends and React/TypeScript interfaces. My clinical and research background shapes how I approach data, explain decisions and design software for the people using it.
Open to senior software engineering opportunities.
