Prakhar Porwal, 21

I'm Prakhar Porwal, a Full-Stack & AI Engineer specializing in LLM-powered systems, scalable backend architectures, and workflow automation using MCP and n8n.

Previously fine-tuned LLMs at Ethara AI (MultiMango). Before that: built scalable full-stack apps serving 10,000+ monthly users at The Social Artist.

I work primarily with Next.js, TypeScript, Node.js, PostgreSQL, and LangChain, and adapt to whatever the problem requires.

10+ Projects shipped. 200+ DSA problems solved on LeetCode. Research paper co-authored at ICDPN-2025 (Springer).

Open to Work: Full-Time, Freelance, or Collabs. Let's talk.
