SOPHINIUS KOECH
@sophiniuskoech
I build secure software, optimize databases, and maintain reliable network infrastructure.
KenyaWhat I'm looking for
I've supported public-sector ICT operations at Kenya National Highways Authority, maintaining and optimizing regional LAN and WAN connectivity while providing tier-1 support and endpoint security compliance.
At the National Environment Management Authority, I optimized SQL queries for environmental compliance logs, reducing report generation time by 90%. I also helped maintain the Licensing and Compliance Portal and implemented authentication and role-based access control for more than 100 users.
Through freelance software engineering, I've delivered custom software solutions focused on scalable architecture and efficient database management. I built an E-Housing web application with Node.js and React for house booking, management, payment-outcome monitoring, and booking-trend tracking.
I'm grounded in software engineering, databases, network integrity, web security, and data intelligence, and I focus on improving system availability, data integrity, and organizational workflows.
