Yuvraj Singh — Software Engineer | Full-stack, AI and real-time systems

Software Engineer · Full-stack & AI/ML
SDE at Innovativus · B.Tech CSE, VIT · Uttarakhand, India

LinkedIn   /   Email   /   Recruiter overview   /   Open source   /   Selected projects

I build LLM agents, retrieval systems and real-time web applications. My work spans Python and TypeScript backends, React interfaces, model evaluation, and Solana/Ethereum integrations. At work, my focus includes voice AI, speech synthesis and conversational assistants.

Open Source

Eight projects, about 600k stars between them. Eight of my patches are merged upstream, and five more are in review.
Mostly small correctness fixes in code I hit while building something else.
