I'm Saurabh Sharma, a software engineer based in London with 14+ years spent taking products from zero to one — at startups I helped found and at companies like Google and Grab. Today I'm the founding engineer at Havenwise, building the backend platform, mobile app and AI features behind smarter home heating. Before that I co-founded Championfy, a competitive casual gaming startup we scaled across Southeast Asia and sold to Ampverse.
