Elizabeth Osunsanwo
Full-Stack Software Engineer | Civic Technology & Digital Public Infrastructure
I'm a Full-stack Software Engineer
About
I am a full-stack software engineer with an MSc in International Relations, specialising in civic technology and digital solutions for public-interest challenges.
My work sits at the intersection of technology, public policy and people. I build systems that help communities engage with civic issues, navigate public services and turn real-world problems into structured, actionable information. My civic-tech work includes StreetLens, a housing and renters' rights platform, and EcoScan+, a smart-city sustainability and civic-engagement application.
I moved into technology because I wanted to bridge the gap between people, policy and implementation. My long-term interest is in using technology to make public systems more accessible, transparent and responsive.
