👋 About Me

I'm a versatile software engineer who builds across the full stack, AI/ML, Web3, and cloud-native infrastructure — going deep, not surface-level. I've shipped production web apps, LLM-powered systems and autonomous agents, on-chain Solana & Ethereum programs, and DevOps pipelines that ship and scale. I build things that run at scale and stay running.

🔭  Currently    →  SDE Intern, building real-time + AI systems
🌱  Learning     →  LLM internals, RAG, agentic systems
🤝  Open source  →  GSoC · p5.js · n8n
💬  Ask me about →  LLMs · RAG · Next.js · Solana · Kubernetes
📫  Reach me     →  yuvrajsingh9027249999@gmail.com
⚡  Fun fact     →  I train & fine-tune LLMs for fun
