Sagar Tamang

Sagar Tamang is an AI engineer and builder based in Bangalore, better known online as sagar builds, where he ships working software to an audience of nearly 150,000+ followers on Instagram. He builds real-time multimodal agents in the open - systems that listen, see, and act on real hardware rather than staying inside a chat window. F.R.I.D.A.Y., his voice assistant that lives inside the computer with hands, has passed 1,500+ stars on GitHub and been watched over 10 million times. Its successor ULTRON - a voice agent that unlocks and operates physical Android devices over the Model Context Protocol - drew 5 million-plus views and 230+ stars within a week of release. Both are fully open source: architecture, code, and the parts that broke.
