I'm Sisay Mehari. I build web apps that solve real problems for real people — from AI-powered platforms to mobile apps. My work is live, not just on slides.
An AI-powered biodiversity reporting platform for the UK. Citizens report wildlife sightings and environmental threats — the AI identifies species, maps reports in real time, and sends alerts directly to local authorities. Built from scratch and deployed live.
The companion mobile app for NatureTrace. Report wildlife sightings and environmental threats directly from your phone, with AI species identification and real-time map updates. Built with React Native and Expo for both iOS and Android.
An open-source platform where local charities post what they need — volunteers, food, clothing, equipment, or skills — and community members can offer to help. Built as the foundation of a larger Community OS vision for the charity sector.
I'm a frontend developer based in London. I taught myself to code and built real, deployed products — not just tutorials and toy projects.
My biggest project is NatureTrace — a full-stack AI platform I built from scratch that's live on the web and as a mobile app. It won 1st place at the Tech4Positive Futures: Youth Voices competition at Google London in 2026.
I'm available for freelance projects — particularly for charities, NGOs, and small organisations that need a developer who cares about impact, not just code.
I'm open to freelance work, collaborations, and conversations. If you have something you want to build, reach out.
