Hey all, I'm Rui. 7+ yrs building web apps and AI stuff, based in the Philippines. Before freelancing I did on-device body tracking at Nex. Lately it's mostly LLM features and AI agents. The model is rarely the hard part. Getting it to say "I don't know" instead of guessing takes most of the time. What are you all working on right now? My work: ruijin2026.vercel.app
