I'm Sisay Mehari. I build web and mobile apps that solve real problems for real people — from AI-powered platforms to tools for local communities.
An AI-powered biodiversity reporting platform for the UK. Citizens photograph wildlife or environmental threats — the AI identifies the species, reports appear on a live map in real time, and each one is routed to the organisation best placed to act. 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 full-stack developer based in London. I taught myself to code and have built and deployed real products.
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.
